Description
Technical Field
The present disclosure relates to the field of network devices, and in particular, to a method and an apparatus for routing information distribution and gateway device switching.
Background
An enterprise deploys two gateway devices, a main gateway device and a standby gateway device of the main gateway device for monitoring whether the main device fails or not and taking over the failure.
Generally, a gateway device has a plurality of Virtual Local Area Network (VLAN) interfaces for transmitting and receiving a packet, and a standby gateway device backs up routing information between VLAN interfaces learned by a primary device. Each VLAN interface corresponds to one or more member ports, which may be ordinary physical ports or dynamic aggregation ports aggregated by a plurality of physical ports. The state of the VLAN interface depends on the state of the member interface, if the member interfaces are all in the inactive state, the corresponding VLAN interface is also in the inactive state, and if one member interface is in the active state, the corresponding VLAN interface is also in the active state.
After monitoring that the main gateway device fails to transmit, the standby gateway device suspends message transmission and reception, and the standby gateway device releases the silent mode. After the standby gateway device releases the silent mode, the dynamic aggregation port determines the state of the dynamic aggregation port by negotiating with an opposite terminal device, wherein the state of part of the VLAN interfaces depends on the state of the dynamic aggregation port and is changed from an inactivated state to an activated state, the standby gateway device monitors that the VLAN interfaces are changed from the inactivated state to the activated state, and relevant routing information is issued aiming at the VLAN interfaces. After the routing information is issued, the standby gateway device completes the active-standby switching with the main gateway device.
However, when the standby gateway device issues the routing information related to a certain VLAN interface, it will issue the routing information related to the VLAN interface to each VLAN interface in an active state that needs the routing information of the VLAN interface.
Disclosure of Invention
In order to overcome the problem of long interruption time of the message forwarding service, the present specification provides a method and an apparatus for issuing routing information and switching gateway devices.
The present description provides a method for issuing routing information, which is applied to a standby gateway device and includes:
aiming at each VLAN interface of the standby gateway equipment, judging whether a member port set corresponding to the VLAN interface comprises a dynamic aggregation port or not;
if the judgment result is yes, setting the VLAN interface to be in an activated state, and removing the state dependency relationship of the VLAN interface to the corresponding member port set;
and sending routing information to each VLAN interface in an activated state.

and the gateway equipment switching module is used for starting to execute the active-standby switching between the gateway equipment and the main gateway equipment and determining the state of the dynamic aggregation port through a Link Aggregation Control Protocol (LACP) message.
In the technical solution of the embodiment of the present specification, when the main gateway device operates normally, the standby gateway device traverses all VLAN interfaces, forcibly sets a VLAN interface including a dynamic aggregation port to an active state for a corresponding member port set, and removes a state dependency relationship of the VLAN interface on the corresponding member port set, and when the standby gateway device monitors that a VLAN interface is changed from an inactive state to an active state, issues routing information for the VLAN interface. When the standby gateway device detects that the main gateway device fails, the main gateway device suspends message receiving and sending, the standby gateway device releases the silent mode and starts switching between the main gateway device and the standby gateway device, and because the corresponding member port set including the VLAN interface of the dynamic aggregation port is forcibly set in an activated state, the related routing information is completely issued, and the standby gateway device can start to forward the message after determining the state of each dynamic aggregation port through the LACP message.
According to the technical scheme of the embodiment of the specification, when the main gateway device fails, the standby gateway completes the issuing of the required routing information in advance, so that the standby gateway device can complete the main-standby switching with the main gateway device only after determining the state of the dynamic aggregation port, replaces the original main gateway device and starts to forward the message service, the switching efficiency between the main gateway device and the standby gateway device is improved, the time for the standby gateway device to issue the routing information in the switching process of the main gateway device and the standby gateway device is shortened, and the interruption time for forwarding the message service is shortened.

Detailed Description
A dual-configuration synchronous interface and a dual-heartbeat interface exist between main and standby gateway devices deployed by an enterprise, the standby gateway device can receive and transmit heartbeat messages through the dual-heartbeat interface to determine whether the main gateway device fails, and routing information between VLAN interfaces learned by the main gateway device can be backed up through the dual-configuration synchronous interface.
The VLAN interface corresponds to one to multiple member ports, that is, the VLAN interface corresponds to a member port set, the set at least includes one member port, and the member port may be a common physical port or a dynamic aggregation port in which a gateway device aggregates a plurality of common physical ports. Each member port has two states, an activated state (also called up state) and an inactivated state (also called down state), and each VLAN interface also has two states, an activated state and an inactivated state, the state of the VLAN interface depends on the member port set corresponding to the VLAN interface, if all the member ports are in the inactivated state, the corresponding VLAN interface will also be in the inactivated state, and if one of the member ports is in the activated state, the corresponding VLAN interface will also be in the activated state. When monitoring that a certain VLAN interface changes from an inactive state to an active state, the gateway device issues routing information including VLAN interface information to each VLAN interface in the active state that needs the VLAN interface information. Similarly, when the gateway device detects that a VLAN interface changes from an active state to an inactive state, it deletes the routing information associated with the VLAN interface from the routing information table corresponding to each VLAN interface.
Before the standby gateway device does not monitor that the main gateway device fails (or is abnormal), the standby gateway device is in a silent mode, and the remaining physical ports except the physical ports corresponding to the dual-configuration synchronous interface and the dual-heartbeat interface cannot receive and transmit messages. Since the dynamic Aggregation interface needs to negotiate the state of the dynamic Aggregation interface with an opposite device to receive and transmit a Link Aggregation Control Protocol (LACP) message, the dynamic Aggregation interface of the standby gateway device in the silent mode is inevitably in an inactive state. For a normal physical port, the state is not affected by the silent mode. Therefore, the state of some VLAN interfaces may depend on the state of the dynamic aggregation port, for example, the member port set includes only a VLAN interface of the dynamic aggregation port, such as VLAN interface 3 shown in fig. 1, or includes both a normal physical port and a dynamic aggregation port, but the normal physical port is in an inactive state, such as VLAN interface 2 shown in fig. 1.
When the standby gateway device detects that the main gateway device fails, the main gateway device suspends message sending and receiving, and the standby gateway device releases the silent mode and starts the active-standby switching with the main gateway device. After the standby gateway device releases the silent mode, the standby gateway device can receive and transmit the LACP message through a common physical port in the dynamic aggregation port, thereby negotiating the state of the dynamic aggregation port with the opposite terminal device. Most dynamic aggregation ports are in an activated state after negotiation, and for a VLAN interface of which the state depends on the state of the dynamic aggregation port, the state is changed from an inactivated state to an activated state, and when the standby gateway device monitors that the VLAN interface of which the state is changed from the inactivated state to the activated state exists, the standby gateway device issues related routing information aiming at the VLAN interfaces.
However, when a certain VLAN interface changes from an inactive state to an active state and routes information is delivered to the VLAN interface, route information including the VLAN interface is delivered to each VLAN interface requiring the route information of the VLAN interface, such as the three VLAN interfaces shown in fig. 1, assuming that VLAN interface 1 and VLAN interface 2 are both in an active state and VLAN interface 3 changes from an inactive state to an active state, when routes information is delivered, all routes information related to VLAN interface 3 is searched and delivered, routes information related to VLAN interface 1 forwarded to VLAN interface 3 is delivered to VLAN interface 1, routes information related to VLAN interface 2 forwarded to VLAN interface 3 is delivered to VLAN interface 2, and routes information related to VLAN interface 3 forwarded to VLAN interface 1 or VLAN interface 2 is delivered to VLAN interface 3.
In addition, the member port sets corresponding to some VLAN interfaces are the same, as shown in fig. 1, it is assumed that both VLAN interface 3 and VLAN interface 4 use the member ports of the member port set to transmit and receive messages, and the member port sets corresponding to VLAN interface 3 and VLAN interface 4 are both the member port set 3. The member port set 3 only includes the dynamic aggregation port 2, and therefore, the states of the VLAN interface 3 and the VLAN interface 4 are both dependent on the state of the dynamic aggregation port 2 of the member port set 3.
If a lot of VLAN interfaces or a lot of routing information exist, the routing information is issued very slowly, and in the process of switching the master and standby gateway devices, a lot of VLAN interfaces change from an inactive state to an active state along with the state of the dynamic aggregation port, which results in that many routing information need to be issued, therefore, the switching time of the master and standby gateway devices is prolonged, and the interruption time of the message forwarding service is long.
In one or more embodiments of the present disclosure, when the primary gateway device operates normally, the standby gateway device may traverse all VLAN interfaces, force a VLAN interface including a dynamic aggregation port to an active state for a corresponding member port set, and remove a state dependency relationship of the VLAN interface on the corresponding member port set, and issue routing information for the VLAN interface after the standby gateway device monitors that the VLAN interface is changed from an inactive state to an active state. When the standby gateway device detects that the main gateway device fails, the main gateway device suspends message receiving and sending, the standby gateway device releases the silent mode and starts switching between the main gateway device and the standby gateway device, and because the corresponding member port set including the VLAN interface of the dynamic aggregation port is forcibly set in an activated state, the related routing information is completely issued, and the standby gateway device can start to forward the message after determining the state of each dynamic aggregation port through the LACP message.
By using one or more embodiments of the present disclosure, when a failure occurs in a main gateway device, because a standby gateway completes issuing required routing information in advance, the standby gateway device only needs to determine the state of a dynamic aggregation port to complete the main-standby switching with the main gateway device, and replaces the original main gateway device to start a message forwarding service, thereby improving the switching efficiency between the main gateway device and the standby gateway device, reducing the time for the standby gateway device to issue routing information during the switching process of the main gateway device and reducing the interruption time of the message forwarding service.

For example, the first information may also be referred to as second information, and similarly, the second information may also be referred to as first information, without departing from the scope of the present specification. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
The following provides a detailed description of examples of the present specification.
The method or the device of the specification is applied to the standby gateway equipment in the dual-computer hot standby, and the gateway equipment can be a router, a three-layer switch, firewall equipment and the like.
As shown in fig. 2, fig. 2 is a schematic flow chart of a routing information issuing method according to an exemplary embodiment in this specification, and includes the following steps:
When the standby gateway device is initialized, each VLAN interface of the standby gateway device may be traversed first, and whether the member interface corresponding to the VLAN interface is assessed to include a dynamic aggregation port is determined.
Of course, it may also be that each VLAN interface of the gateway device is periodically traversed, and whether the member interface corresponding to the VLAN interface is assessed to include the dynamic aggregation port is determined.
In addition, when a VLAN interface is created, every time a VLAN interface is created, it may be determined whether the member port set corresponding to the VLAN interface includes a dynamic aggregation port.
if the member port set corresponding to the VLAN interface is judged to include the dynamic aggregation port, it is described that the state of the VLAN interface depends on the state of the dynamic aggregation port in the member port set corresponding to the VLAN interface, so that the VLAN interface is set to an activated state, and the state dependency relationship of the VLAN interface on the corresponding member port set is released.
In practical application, when it is monitored that all the member ports in the member port set corresponding to the VLAN interface are in an inactivated state, the state of the VLAN interface is rejected from being changed, so as to release the state dependency relationship of the VLAN interface on the corresponding member port set. Specifically, when all the member ports of the member port set are in the inactive state, a prompt is given to the system, and after receiving the prompt, the system responds to the prompt and changes the VLAN interface corresponding to the member port set to the inactive state. If the VLAN interface is forced to be in the activated state, the system does not respond any more when receiving the prompt of the aggregation interface corresponding to the VLAN interface, and the VLAN interface is not changed into the inactivated state.
Furthermore, in some cases, it is necessary to change the attribute of the VLAN interface, that is, change the member port in the member port set corresponding to the VLAN interface. If the member port set port corresponding to the changed VLAN interface does not include the dynamic set port, a dynamic aggregation port is newly added to the member port set during the change, and at this time, the VLAN interface may be set to an active state, and the state dependency of the VLAN interface on the member port set is released.
It should be noted that as long as the standby gateway device is in the silent mode, all the dynamic aggregation ports are necessarily in the inactive state, and even if the VLAN interface corresponding to the dynamic aggregation port is forced to be in the active state, the dynamic aggregation port is still in the inactive state because the silent mode cannot receive and transmit a message.
And step 206, sending the routing information to each VLAN interface in the activated state.
When the standby gateway device detects that a certain VLAN interface is changed from an inactivated state to an activated state, the standby gateway device issues related routing information aiming at the VLAN interface. Specifically, assuming that there is a VLAN A, VLAN B, VLAN C, VLAN interface D, a VLAN A, VLAN interface B is in an activated state, and a VLAN C, VLAN interface D is in an inactivated state, at this time, the VLAN interface D is changed from the inactivated state to the activated state, after monitoring that the VLAN interface D is changed from the inactivated state to the activated state, the standby gateway device searches for routing information for the VLAN interface D, that is, searches for routing information between the VLAN interface D and each VLAN interface in an activated state, including routing information between the VLAN interface D and the VLAN interface a, and routing information between the VLAN interface D and the VLAN interface B, and then issues the searched routing information to the VLAN A, VLAN interface B, VLAN interface D. Certainly, if there is no corresponding routing information between VLAN interface D and VLAN interface a, it is not necessary to issue relevant routing information to VLAN interface a.
It should be noted that the routing information issuing method shown in fig. 2 is executed by the standby gateway device when the main gateway device operates normally.
Based on the routing information issuing method, the present application also provides a gateway device switching method, as shown in fig. 3, including the following steps:
Before the standby gateway device does not detect that the main gateway device fails, the standby gateway device is always in a silent mode, when the standby gateway device detects the main gateway device, the main gateway device can suspend message receiving and sending, and the standby gateway device can remove the silent mode.
After the standby gateway device releases the silent mode, it starts to execute the main/standby switch with the main gateway device, at this time, all physical ports can receive and transmit messages, so the standby gateway device can determine the state of the dynamic convergence port by receiving and transmitting the LACP messages with the opposite device. Before the standby gateway device is not switched, the VLAN interfaces of the corresponding member port set including the dynamic aggregation ports are all forced to be in an activated state, and relevant routing information is issued and completed, so that the standby gateway device and the opposite device can start to forward the service of the packet after negotiating and determining the state of each dynamic aggregation port.
When determining the state of the dynamic aggregation port, the determined state may be an activated state or an inactivated state.
After the standby gateway device becomes the master gateway device, because the standby gateway device is no longer in the silent mode, the state of each dynamic aggregation port is not affected by the silent mode, and therefore, after the standby gateway device becomes the master gateway device (after the standby gateway device determines the state of the dynamic aggregation port), the state dependency relationship of the VLAN interface on the corresponding member port set can be restored for each VLAN interface of the corresponding member port set, where the corresponding member port set includes the dynamic aggregation port. That is, if all the member ports in the member port set are in the inactive state, the corresponding VLAN interface will be in the inactive state, and if one of the member ports in the member port set is in the active state, the corresponding VLAN interface will be in the active state.
In practical application, if the master-slave switching between the master gateway device and the slave gateway device is started, the state dependency relationship of the VLAN interface on the corresponding member port set is restored, and part of the dynamic aggregation ports have not yet determined the state, so that part of the VLAN interfaces that have been forced to be in the activated state before are affected by the dynamic aggregation ports that have not been determined to be in the inactivated state, and after the state of the part of the dynamic aggregation ports is determined, some of the dynamic aggregation ports determine to be in the activated state, so that some VLAN interfaces are affected and changed from the inactivated state to the activated state, at this time, some routing information needs to be re-issued, and the switching time between the master gateway device and the slave gateway device is also delayed.
Therefore, a timer can be created when the standby gateway device starts to execute the main-standby switching with the main gateway device, and when the timer is triggered, the state of the dynamic aggregation port is judged and determined; and when the timer is not triggered, judging that the state of the dynamic aggregation port is not determined. Specifically, when the standby gateway device starts to execute the main-standby switching with the main gateway device, timing is started, after a preset time period, the standby gateway is considered to be switched to the main gateway device, and then the state dependency relationship of the VLAN interface on the corresponding member port set is recovered for each VLAN interface of the corresponding member port set including the dynamic aggregation port. The timer or the preset time length is an estimation for determining the time length of the dynamic aggregation port of the standby gateway equipment. Therefore, the situation can be effectively avoided.
In practical application, after the standby gateway device is switched to the main gateway device, each VLAN interface may be traversed, and the VLAN interfaces in which all the member ports in the corresponding member port set are in the inactive state are set to the inactive state.
The present specification also provides a routing information issuing apparatus, as shown in fig. 4, where the apparatus is applied to a standby gateway device, and includes:

and the member port set changing module is used for setting the VLAN interface to be in an activated state and removing the state dependency relationship of the VLAN interface on the corresponding member port set when a dynamic aggregation port needs to be newly added to the member port set corresponding to the VLAN interface aiming at the VLAN interface of which the corresponding member port set does not comprise the dynamic aggregation port.
