Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one.
Specifically, in the related art, the operation mode of the policy routing under the general condition is as follows: configuring ACL matching entries and configuring a redirected forwarding path thereof, wherein the path is generally a local forwarding outlet Internet Protocol (IP) address; and generating an ACL rule from the ACL matching entries and binding a port or VLAN, wherein a message received by the port or the VLAN is matched with the ACL rule, and if the matched entry is hit, forwarding the matched entry according to a redirection forwarding path of the matched entry. The operation mode of the policy routing can only configure and match local IP addresses, but can not match and search for remote IP addresses which cannot be found locally and can be reached through a tunnel.
For the above defects, in this embodiment, when a target IP address of a packet to be transmitted is unreachable through a local route, a target virtual node corresponding to the target IP address is determined, where a first correspondence relationship is preset between the target virtual node and reachable path information of the target IP address, the reachable path information includes an egress next hop address of a reachable path of the target IP address, and the packet to be transmitted is forwarded to the egress next hop address through the target virtual node based on the first correspondence relationship; therefore, the target virtual node corresponds to the target IP address, and the target virtual node corresponds to the reachable path information of the target IP address, so that the message to be transmitted can be forwarded to the next hop address of the outlet of the reachable path through the target virtual node, and at the moment, the target IP address can reach through the reachable path, namely, the message to be transmitted can be transmitted to the target IP address through the next hop address of the outlet of the reachable path, so that when the target IP address is the unreachable remote IP address of the local route, the pointing setting of the policy route to the remote IP address can be completed, the message to be transmitted can be transmitted to the target IP address, and the target address of the policy route can be pointed to the remote outlet.
The following describes in detail a message transmission method provided in the embodiments of the present application with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Fig. 1 shows the flow steps of a message transmission method provided by an embodiment of the present invention, where the method may be executed by an electronic device, and the electronic device may include: a server and/or a terminal device. In other words, the method may be performed by software or hardware installed in the electronic device, the method comprising the steps of:
step 101: and under the condition that the target IP address of the message to be transmitted cannot be reached through the local route, determining a target virtual node corresponding to the target IP address.
A first correspondence relationship is preset between the target virtual node and reachable path information of the target IP address, where the reachable path information includes an exit next hop address of a reachable path of the target IP address.
Specifically, in this embodiment, when the target IP address of the packet to be transmitted is unreachable through the local route, the reachable path of the target IP address may be determined first, and a first corresponding relationship between the target virtual node and reachable path information of the target IP address is established, so as to implement binding between the target virtual node and reachable path information of the target IP address; in addition, the target virtual node has a corresponding relationship with the target IP address as well.
Therefore, when the IP address of the message to be transmitted is determined to be the target IP address, the target virtual node corresponding to the target IP address can be determined, and at the moment, because the first corresponding relation exists between the target virtual node and the reachable path information of the target IP address, the reachable path information comprises the next hop address of the outlet of the reachable path of the target IP address, the message to be transmitted can be forwarded to the next hop address of the outlet through the target virtual node when the message to be transmitted points to the target virtual node, and the accurate forwarding process of the message to be transmitted through the target virtual node is realized.
Step 102: and forwarding the packet to be transmitted to the outlet next hop address through the target virtual node based on the first corresponding relation.
The first corresponding relation is preset between the target virtual node and the reachable path information of the target IP address, so that the message to be transmitted can be forwarded to the next hop address of the outlet of the reachable path of the target IP address through the target virtual node based on the first corresponding relation, at the moment, the message to be transmitted can be continuously transmitted to the target IP address after being forwarded to the next hop address of the outlet of the reachable path because the reachable path can reach the target IP address, and the target IP address of the message to be transmitted can be pointed to the target IP address under the condition that the target IP address of the message to be transmitted cannot be reached through a local route.
Specifically, in an embodiment, before determining the target virtual node corresponding to the target IP address, the method further includes the following steps:
determining a reachable path to the IP address based on the IP address and a preset routing table, wherein the reachable path pointing to the IP address is stored in the routing table;
and establishing a second corresponding relation between the IP address and reachable path information of the reachable path, wherein the IP address comprises the target IP address.
Specifically, the routing table stores reachable paths pointing to the IP addresses, so that the reachable paths to the IP addresses can be determined by querying the routing table based on the IP addresses, and a second correspondence between the IP addresses and reachable path information of the reachable paths is established.
In addition, in an embodiment, before determining a target virtual node corresponding to a target IP address, the exit of the reachable path may be set as the virtual node, and a corresponding relationship between reachable path information of the IP address and the virtual node may be established.
Specifically, by setting the outlet of the reachable path as a virtual node, and because the IP address includes the target IP address, that is, the outlet of the reachable path of the target IP address is the target virtual node, the target virtual node corresponding to the target IP address can be determined according to the target IP address and the reachable path information corresponding to the target IP address, so that if the local route of the configured IP address is found to be unreachable when the policy route is configured, the policy route can be directed to the virtual node corresponding to the IP address, and the direction setting of the policy route to the IP address can be completed. In addition, by establishing the corresponding relationship between the reachable path information of the IP address and the virtual node, since the IP address includes the target IP address, that is, the corresponding relationship includes the first corresponding relationship between the reachable path information of the target IP address and the target virtual node corresponding to the target IP address, the first corresponding relationship between the reachable path information of the target IP address and the target virtual node corresponding to the target IP address is obtained through the corresponding relationship, so that the packet to be transmitted can be forwarded to the next hop address of the outlet of the reachable path of the target IP address.
In addition, the reachable path of the IP address may be changed, and in one embodiment, when the reachable path of the target IP address is changed, the first corresponding relationship may be updated to a third corresponding relationship between the target virtual node and reachable path information of the reachable path after the change.
It should be noted that the change of the reachable path may include deletion, addition, reconstruction, and the like of the path, so that the first corresponding relationship is updated to the third corresponding relationship between the target virtual node and the reachable path information of the reachable path after the change when the reachable path of the target IP address is changed, thereby implementing a process of maintaining real-time update of the reachable path information corresponding to the target virtual node, and ensuring that the pointing path of the target virtual node is correct.
Furthermore, an exit next hop address of the reachable path of the IP address may change, and in an embodiment, when the exit next hop address of the reachable path changes, the exit next hop address included in the reachable path information in the first corresponding relationship may be modified to the changed exit next hop address.
Specifically, if the reachable path is not changed, but only the egress next hop address of the reachable path is changed, the egress next hop address included in the reachable path information in the first corresponding relationship may be modified into the changed egress next hop address, so that the target virtual node does not need to perform any action, and the egress information of the target virtual node can be directly changed along with the change of the egress information of the reachable path.
In addition, the target virtual node may be a virtual port or a loopback port, the reachable path may be a tunnel, the reachable path information further includes tunnel information, and the packet to be transmitted may be forwarded to the egress next hop address by the target virtual node based on the first correspondence in different manners for different target virtual nodes. This will be explained below.
In an embodiment, when the target virtual node is a virtual port and the reachable path is a tunnel, the reachable path information further includes tunnel information, and forwarding, by the target virtual node, the packet to be transmitted to the egress next hop address based on the first correspondence may include the following steps:
and based on the first corresponding relation, encapsulating the tunnel information and the message to be transmitted, and transmitting the encapsulated message to the tunnel through the virtual port and directly reaching the next hop address of the outlet corresponding to the tunnel.
Specifically, if the device chip supports the virtual port function, the virtual port may be directly used as a target virtual node, that is, the reachable path information of the virtual port and the target IP address is bound, and when the outlet issued by the policy routing is the target IP address, a virtual port is first allocated to the policy routing, the policy routing is directly directed to the virtual port, and the relationship between the virtual port and the target IP address is recorded. Meanwhile, the reachable path is searched in the device, and after the reachable path is found, the next hop address of the reachable path is directly written into the virtual port table of the virtual port, namely, the virtual port directly points to the outlet which can reach the target IP address. Thus, after the message to be transmitted hits the policy route, the message to be transmitted is directed to the virtual port for forwarding, and the virtual port directly directs the message to be transmitted to the real next hop outlet capable of transmitting the target IP address.
In addition, since the virtual port supports direct encapsulation of tunnel information, when the packet to be transmitted is forwarded to the exit next hop address through the target virtual node, the tunnel information and the packet to be transmitted can be encapsulated, and the encapsulated packet is transmitted to the tunnel through the virtual port and reaches the exit next hop address corresponding to the tunnel.
In an embodiment, when determining the exit next hop address of the tunnel, the exit next hop address of the tunnel may be determined based on a preset tunnel table, where the exit next hop address of the tunnel is stored in the tunnel table.
This case is explained below by a specific example. Referring to the information query diagram shown in fig. 2, in one embodiment, it is assumed that 10.10.10.1 is redirected to 1.1.1.1, the target IP address is 1.1.1.1, and the target IP address 1.1.1 needs to be reachable through a Multi-Protocol Label Switching (MPLS) tunnel 1.
Assuming that the target virtual node is a virtual port, the message forwarding can be performed through the following processes:
step 21, the policy routing issues 10.10.10.1 redirection to target IP address 1.1.1.1.
And step 22, the device searches for 1.1.1.1 in the routing table, and if the device is found to be unreachable, the iterative search process is started.
And step 23, the device searches for the reachable path of 1.1.1.1 through the routing table in an iterative manner, and finds that the MPLS tunnel1 is reachable.
Step 24, a virtual port (VP 1) is allocated to the target IP address 1.1.1.1, and the policy route 10.10.10.1 is redirected to VP1.
Step 25, looking up the next hop address of the exit of the MPLS tunnel1 through the tunnel table, and finding out that the exit in the chip is the next hop nexthop1001.
Step 26, directing the outlet of VP1 to the outlet nexthop1001 of MPLS tunnel1, that is, establishing a corresponding relationship between the virtual port and reachable path information, which may also be referred to as a virtual port table; in addition, a next hop (nexthop) table can be established, and the table contains specific exit information, tunnel information and the like of the tunnel.
And 27, recording the corresponding relation between the VP1 and the 1.1.1.1, and refreshing the new nexthop pointing relation of the VP1 if the tunnel deletion addition or reconstruction of the 1.1.1.1 is reached.
Through the above steps, all actions of the whole policy routing to the target IP address 1.1.1.1 are completed, and it can be seen from the above operation that the exit of the tunnel1 of MPLS is the chip exit nexthop1001, and at the same time, the exit of VP1 also points to this nexthop1001, so if the tunnel exit information of MPLS changes (not the deletion or addition of the tunnel itself), there is no need to process VP1, and the exit information of VP1 automatically changes with the change of nexthop1001. If the tunnel reaching the target IP address 1.1.1.1 changes (adds, deletes, and rebuilds), the tunnel pointing information of VP1 needs to be refreshed according to the correspondence between 1.1.1.1 and VP1.
In another embodiment, when the target virtual node is a loopback port and the reachable path is a tunnel, the reachable path information further includes tunnel information, and forwarding, based on the first correspondence, the packet to be transmitted to the egress next hop address through the target virtual node includes:
based on the first corresponding relation, transmitting the message to be transmitted to the tunnel through the loopback port; and encapsulating the tunnel information and the message to be transmitted, and sending the tunnel information and the message to be transmitted to the next hop address of the outlet.
Specifically, if the device chip does not support forwarding of the policy routing and encapsulation of the tunnel at one time, that is, iteration of tunnel encapsulation cannot be supported (some chips consider that forwarding of the policy routing is a primary forwarding behavior, encapsulation of the tunnel is another primary forwarding behavior, and the chip cannot perform two behaviors in one-time forwarding), at this time, the loopback port can be used as the target virtual node. If the tunnel information corresponding to the target IP address is found, the tunnel information can be processed separately, that is, firstly, the policy routing outlet with the target IP address as the target IP address points to a loopback port, and the related information of the tunnel is configured on the loopback port, so that after the message to be transmitted is matched with the policy routing with the target IP address as the target IP address for the first time, the message to be transmitted is transmitted to the loopback port to finish the forwarding action of the first policy routing, then the message to be transmitted enters the tunnel from the loopback port in a loopback mode, the tunnel information is encapsulated, the message is transmitted from the real outlet of the tunnel found by the target IP address, and the forwarding action of the second tunnel encapsulation is finished.
This case is explained below by a specific example. Referring to the information query diagram shown in fig. 3, in one embodiment, assume that 10.10.10.1 is redirected to 1.1.1.1, the destination IP address is 1.1.1.1, and the destination IP address 1.1.1.1 needs to be reachable through MPLS tunnel 1.
Assuming that the target virtual node is a loopback port, the message can be forwarded through the following processes:
step 31, the policy routing issues 10.10.10.1 redirection to the target IP address 1.1.1.1.
Step 32, the device searches for 1.1.1.1 in the routing table, and if the device is found to be unreachable, the iterative search process is started.
And step 33, the equipment iteratively searches for the reachable path of 1.1.1.1 through the routing table, and finds that the MPLS tunnel1 is reachable.
And step 34, allocating a loopback port loopback1 for 1.1.1.1, and redirecting the policy route 10.10.10.1 to loopback1.
Step 35, finding the exit next hop address of the MPLS tunnel1, and finding that the exit in the chip is the next hop nexthop1001.
Step 36, setting the loopback1 port to access the MPLS tunnel1, and at this time, an access table may be established, that is, only the message entering from the loopback port loopback1 will directly enter the MPLS tunnel1 for tunnel encapsulation, and is sent from the nexthop1001 at the exit of the tunnel 1.
And step 37, recording the corresponding relation between the loopback1 and 1.1.1.1, and refreshing the port access relation of the new MPLS tunnel of the loopback1 if the tunnel deletion addition or reconstruction of 1.1.1.1 is reached.
All actions of pointing the whole policy route to the target IP address 1.1.1.1 are completed, and it can be seen from the above operations that when the chip does not support the completion of policy route forwarding and tunnel encapsulation at one time, the policy route pointing can be completed by means of loop back of the loopback1, and the process of pointing the message to the exit nexthop1001 of the MPLS tunnel1 is completed by using the tunnel1 of which the loopback1 accesses the MPLS, and since the loop back1 is pointed to the MPLS tunnel1 itself, the change of the exit of the tunnel1 can be directly reflected to the policy route pointing. If the tunnel reaching the target IP address 1.1.1.1 changes (adds, deletes, and rebuilds), the tunnel pointing information of the loopback1 needs to be refreshed according to the corresponding relationship between 1.1.1.1 and loopback1.
In this way, in this embodiment and related technologies, when the outlets to which the policy routing points are all local reachable IP addresses but cannot point to remote IP addresses, the reachable tunnel information of the target IP address can be directly searched through iteration, the information is bound with the virtual node, and then the policy routing points to the virtual node, so that the pointing setting of the policy routing to the remote target IP address can be completed. Meanwhile, the relation between the virtual node and the far-end target IP address is maintained, so that when the tunnel pointing to the far-end target IP changes, the policy routing does not need to adjust the configuration (always points to the far-end target IP address), and the pointing direction of the policy routing can automatically change. The embodiment expands the use range of the policy routing.
