All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
First, the term "and" in the embodiment of the present application is only one kind of association relationship describing an associated object, and means that three kinds of relationships may exist, for example, a and B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
When the present application refers to the ordinal numbers "first", "second", "third" or "fourth", etc., it should be understood that this is done for differentiation only, unless it is clear from the context that the order is actually expressed.
The scheme of the present application will be described in detail by specific examples, but the present application is not limited to the following examples.
For example, referring to fig. 1, a schematic structural diagram of a network device provided in the present application is shown, in an embodiment of the present application, the network device may be a Spine device (e.g., a core Switch) in a VXLAN networking, the network device includes at least one line Card (LineCard, LC) and a plurality of network boards (Switch Fabric cards, SFCs), and the plurality of network boards of the network device are configured as at least one network board group. As shown in fig. 1, the network device includes a line card 1, a line card 2, … …, and a line card n, wherein 4 screens (screen 1, screen 2, screen 3, and screen 4) are configured on the network device, and the 4 screens are configured into 2 screen groups according to the distance description of the line card 1 and the screen 1, the screen 2, the screen 3, and the screen 4, wherein the screen 1 and the screen 2 form the screen group 1, and the screen 3 and the screen 4 form the screen group 2. The line card 1 is connected with the network of the network boards 1 and 2 through the aggregation group 1 of the HG ports of the local pointing network board group 1 (the network boards 1 and 2), and the line card 1 is connected with the network of the network boards 3 and 4 through the aggregation group 2 of the HG ports of the local pointing network board group 2 (the network boards 3 and 4).
Further, in this embodiment of the present application, a line card of a network device and a switch chip used by a network board may be the same, and then, a host routing table entry on the network board may be used to expand a forwarding table entry of the network device. Specifically, forwarding table entries on a line card of the network device may be configured as a first-class forwarding table entry, and forwarding table entries on a mesh board of the network device may be configured as a second-class forwarding table entry, where each mesh board of the network device is configured as at least one mesh board group, and then, each mesh board group may be further configured as second-class forwarding table entries corresponding to different communication address characteristics, respectively, that is, messages with different communication address characteristics, and the messages are forwarded through different mesh board groups.
Exemplarily, referring to fig. 2, a schematic flow chart of a message forwarding method provided by the present application is shown, where the method is applied to a network device, where the network device includes a line card and a plurality of network boards, the plurality of network boards of the network device are configured as at least one network board group, the line card of the network device is configured with a first type of forwarding table entry, and each network board group of the network device is configured with a second type of forwarding table entry corresponding to different communication address features, and a detailed flow of the message forwarding method is as follows:
step 200: and the line card of the network equipment judges the message type of the received target message and determines the communication address characteristic of the target message when judging that the target message is the second type message.
Further, in this embodiment of the present application, the forwarding and sending of the packet further includes the following steps: when the line card of the network device determines that the target packet is a first packet, the line card forwards the target packet based on the communication address of the target packet and the first forwarding table entry, where in this embodiment, the first packet refers to an IPV6 packet, and the second packet refers to an IPV4 packet or a two-layer packet.
In the embodiment of the present application, a network device is taken as a Spine device (core switch) in VXLAN networking. Specifically, a preferred implementation manner is that the first-type forwarding table entry is a MAC table entry and/or an IPV4 host route, and the second-type forwarding table entry is an IPV6 host route.
That is, the host routing table entries on the line cards of the core switches are configured as MAC entries and/or IPV4 host routing table entries for forwarding IPV4 messages, while the host routing table entries on the net boards of the core switches are configured as IPV6 host routes for forwarding IPV6 messages. That is, the MAC address and the IPV4 host route may be issued on a line card of the core switch (i.e., the core switch maintains the learned MAC address table entry and the IPV4 host route on the line card), and the IPV6 host route may be issued on the network board of the core switch (i.e., the core switch maintains the learned IPV6 host route on the network board).
Certainly, when the network device is a core switch and is used as a Spine device, a large number of local users do not need to be accessed, and a large number of MAC address table entries are not needed, so that the host routing table on the network board can be used as the MAC address table entries without being expanded.
Further, each screen of the core switch is configured as at least one screen group, for example, when the core switch is configured with 6 screens, the number of the screen groups may be configured as 1 group, 2 groups or 3 groups, that is, 6 screens may be regarded as 1 screen group, or 3 screens may be regarded as 1 screen group, or 2 screens may be regarded as 1 screen group. For another example, when the core switch is configured with 4 network boards, the number of the network board groups may be configured as 1 group or 2 groups, that is, 4 network boards may be used as 1 network board group, or 2 network boards may be used as 1 network board group.
It should be noted that a message forwarding rule needs to be configured on a line card of the core switch, that is, when receiving the IPV6 message, the IPV6 message needs to be redirected to a corresponding network board group, and the network board group queries an IPV6 forwarding table entry to forward the IPV6 message.
In this embodiment of the present application, different network board groups on a core switch are used for carrying and forwarding IPV6 messages with different characteristics (e.g., characteristics of a destination communication address carried by an IPV6 message), and a specific packet forwarding policy is described in detail below.
Step 210: and the line card of the network equipment sends the target message to a target network board group based on the communication address characteristic of the target message, wherein the target network board group is configured with a target second-class forwarding table entry corresponding to the communication address characteristic of the target message.
In this embodiment of the application, when the line card of the network device sends the target packet to the target network board set based on the communication address characteristic of the target packet, a preferred implementation manner is that the line card of the network device determines the target network board set corresponding to the communication address characteristic of the target packet based on the communication address characteristic of the target packet; and the line card of the network equipment sends the target message to the target network board group through the aggregation group of the link HG port which locally points to the target network board group.
In practical applications, the network board of the core switch is configured as at least one network board group, and then the core switch may equally distribute the learned IPV6 host routes to the corresponding network board group based on the learned characteristics of the IPV6 host routes.
For example, assuming that 2 mesh groups are configured, the IPV6 host routing table can be divided into 2 according to certain characteristics, and assuming that 3 mesh groups are configured, the IPV6 host routing table can be divided into 3. In a preferred implementation, when the number of the otter board groups is 2, the IPV6 hosts are divided based on the parity row of the last bit, the IPV6 host with the odd number of the last bit is routed to the otter board group 1, and the IPV6 host with the even number of the last bit is routed to the otter board group 2. And when the number of the screen plate groups is 3, taking the last 4 bits of the last 1 byte of the IPV6 host routing, dividing by 3 to obtain remainder, issuing to the first screen plate group when the remainder is 0, issuing to the 2 nd screen plate group when the remainder is 1, and issuing to the 3 rd screen plate group when the remainder is 2.
Further, in this embodiment of the present application, the line card of the core switch is connected to each network board group through the aggregation port of the link HG port that points to each network board group locally, for example, assuming that the network board group 1 includes the network board 1 and the network board 2, on the line card 1 of the core switch, the link HG port 1 and the link HG port 2 aggregate to form the aggregation group 1 of the link HG port, the line card 1 is in communication connection with the network board group 1 through the aggregation group 1 of the link HG port, where the link HG port 1 is in communication connection with the network board 1, and the link HG port 2 is in communication connection with the network board 2.
To sum up, when a line card of a network device receives a host message, it first needs to determine the message type of the host message, that is, determine whether the host message is an IPV6 host message, if the host message is determined to be an IPV6 host message, determine a feature of a destination IPV6 address based on the destination IPV6 address of the IPV6 host message, and determine a target network board group (that is, a network board group for forwarding the IPV6 host message) corresponding to the feature of the destination IPV6 address based on the feature of the destination IPV6 address, and then redirect the IPV6 message to the target network board group by using an aggregation group pointing to a link HG port of the target network board group locally, and forward the IPV6 message by using a network board lookup table in the target network board group.
In practical application, the line card of the network device is in communication connection with each network board through the local link HG port, that is, a plurality of link HG ports for connecting each network board in the network board group 1 are aggregated to form an aggregation group. Then, in the embodiment of the present application, when forwarding an IPV6 packet to a corresponding target network board group, it is preferable to forward the IPV6 packet to one network board in the corresponding network board group, for example, each network board in the network board group forwards IPV6 packet traffic that it is responsible for forwarding in a load balancing manner. When any one screen plate in the screen plate group has a fault, the rest normal screen plates in the screen plate group can be adopted for load sharing. Specifically, the load sharing method is not described herein again.
Step 220: and the target network board group of the network equipment forwards the target message based on the communication address of the target message and the target second-class forwarding table entry.
Specifically, in this embodiment, when the target network board group of the network device forwards the target packet based on the communication address of the target packet and the target second-type forwarding table entry, a preferable implementation manner is that the line card of the network device sends the target packet to a target network board in the target network board group through a target link HG port of an aggregation group which locally points to a link HG port of the target network board group, where the target network board is any one network board in the target network board group.
That is to say, when one network board group is used to forward IPV6 messages, it is essential that one network board in the network board group is used to forward IPV6 messages, and preferably, each network board in one network board group can forward IPV6 message traffic that needs to be forwarded by the one network board group in a load balancing manner.
