- This embodiment includes the method for forwarding access traffic applied to the first dual-homing device as shown in FIG. 1 and the method for forwarding access traffic applied to the second dual-homing device as shown in FIG. 2.
- the first dual-homing device and the second dual-homing device are dual-homing devices in a dual-homing device group, the first dual-homing device is connected to the main network card of the server, and the second dual-homing device is connected to the backup network card of the server.
- the method for forwarding access traffic applied to the first dual-homed device includes: according to pre-configured operating mode control parameters, detecting whether the network card operating mode of the server is a static active/standby mode; wherein the value of the operating mode control parameter is used It indicates the working mode of the network card of the server; if the working mode of the network card of the server is a static active/standby mode, after receiving the unicast traffic on the network side, the unicast traffic on the network side is set as the application protocol synchronization interface The peerlink link interface is synchronized to the first dual-homing device for the first dual-homing device to send unicast traffic on the network side to the server.
- the method for forwarding access traffic applied to the first dual-homed device in this embodiment is shown in FIG. 1, and specifically includes:
- Step 110 Obtain pre-configured working mode control parameters. Among them, the value of the working mode control parameter is used to indicate the working mode of the network card of the server.
- the dual-homing device group includes a main device and a backup device that perform traffic forwarding.
- One side of the dual-homing device group is connected to the server, where the main device is connected to the main network card of the server, and the backup device is connected to the standby network card of the server; the other side of the dual-homing device group is connected to the router.
- the main device is the first dual-homing device
- the backup device is the second dual-homing device.
- the above-mentioned basic parameters include: the main and standby parameters of the dual-homing device group, static and dynamic parameters, priority, system ID, peerlink related configuration parameters, and keepalive link related configuration parameters.
- the MC-LAG device is the main or backup device
- the MC-LAG group is static or dynamic
- the priority of the MC-LAG group is the system ID of the MC-LAG group
- related configurations such as peerlink and keepalive.
- the main and backup devices are determined according to the specific parameter configuration of the two devices in the dual-homing device group. Under normal circumstances, there is no difference in the traffic forwarding behavior of the main and backup devices, and both the main and backup interfaces can carry out traffic. Load sharing and forwarding. In the event of a failure, the behavior of the main and backup devices is different.
- the link supports ordinary Ethernet interfaces and aggregate interfaces.
- the peer-link link is a Layer 2 link used for the exchange of ICBG synchronization information and the transmission of part of the traffic. After an interface is configured as a peer-link interface, no other services can be configured on the interface.
- Peerlink has an isolation function for BUM packet forwarding. When the MC-LAG network is normal, BUM packets received from the peerlink link will no longer be forwarded to the MC-LAG member port, which is the so-called isolation. When the MC-LAG member port is located When the link fails, the isolation function is released, that is, the BUM message received from the peerlink link will be forwarded by the MC-LAG member port.
- Keepalive links heartbeat links, carrying heartbeat data packets, are mainly used for MC-LAG negotiation, active/standby election, and dual-active detection.
- This link and peerlink are two different links and have different functions.
- the keepalive link can be carried by an external network. For example, when MC-LAG is connected to the IP network in the uplink, two dual-homing devices can communicate with each other through the IP network, and this link can be used as a keepalive.
- a single link can be configured as a keepalive link.
- the value of the working mode control parameter is used to indicate the working mode of the network card of the server. For example, when the value of the working mode control parameter is 1, it means The network card of the server works in a static active/standby mode. When the value of the working mode control parameter is 0, it means that the network card of the server works in a load sharing mode. In this step, it is necessary to read the value of the working mode control parameter.
- Step 111 Detect the working mode of the network card of the server, and determine whether it is a static active/standby mode. If the server's network card works in a static active/standby mode, step 112 is executed to synchronize the received network side unicast traffic to the first dual-homed device through the peerlink link interface; if the server's network card works in load sharing In this way, step 113 is executed to forward the traffic in a traditional way.
- the above-mentioned working mode control parameter is represented by the FLAG parameter, and the value of the FLAG parameter includes 0 and 1.
- the obtained FLAG parameter value is 0, it means that the network card of the server is running in load sharing mode. At this time, the dual-homing device group is running in the default MC-LAG working mode, and traffic is forwarded normally.
- the obtained FLAG parameter value is 1, it means that the network card of the server is currently running in a static active/standby mode.
- the server has a primary network card and a backup network card respectively connected to the first and second dual-homed devices, there is only one network card for traffic forwarding at the same time. Therefore, if the traditional MC-LAG mechanism is used for processing, when the upstream and downstream traffic paths are inconsistent, a part of the downstream traffic will be forwarded to the backup network card, resulting in loss of traffic. Therefore, in the embodiments of the present disclosure, the FLAG is set to indicate different traffic forwarding modes of the dual-homing device group.
- Step 112 Synchronize the received unicast traffic on the network side to the first dual-homing device through the peerlink link interface.
- the interface of the peerlink link is set as the synchronous interface of the application protocol; for BUM packet traffic , Let go of the port isolation function of the peerlink link. That is, when the network card of the server is running in static active/standby mode, the processing scheme for traffic forwarding is as follows: First, the two devices in the dual-homing device group are named MC-LAG first dual-homing device and MC-LAG second dual-homing device.
- the member port on the first dual-homing device of MC-LAG is called the first member port of MC-LAG
- the member port on the second dual-homing device of MC-LAG is called the second member port of MC-LAG.
- only the peerlink port is set as the synchronization interface of the application protocol.
- the MC-LAG first dual-homing device synchronizes the source media access control address of the unicast traffic to the synchronization interface through the peerlink link.
- MC-LAG second dual-homed device and forward unicast traffic to the network side;
- MC-LAG second dual-homed device after receiving the unicast traffic sent by the network side, passes the network side unicast traffic through the peerlink chain The path is forwarded to the first dual-homing device of MC-LAG, for the first dual-homing device of MC-LAG to send to the server.

- the flow forwarding process is as follows: When the first member port of MC-LAG receives data flow, it obtains the MAC (source media access control address) of the network side device of the data flow received by the first member port of MC-LAG, and synchronizes the MAC to the pair On the peerlink port of the second dual-homed device of MC-LAG at the end, it forwards data traffic to the network side at the same time. When the data traffic from the router on the network side reaches the first dual-homing device of MC-LAG, it directly queries the MAC table. The traffic is forwarded from the first member port of MC-LAG to the server Serve A, and the data traffic from the network side reaches the MC-LAG.

- the BUM packet traffic from the network side reaches the second dual-homing device of MC-LAG, it will be broadcast to other ports in the same VLAN.
- it is forwarded to the server Serve A from the second member port of MC-LAG, but because the server Server The network card corresponding to A is standby, and the traffic is dropped.
- it broadcasts from the peerlink port to the first dual-homing device of the opposite MC-LAG.
- the traffic When the traffic reaches the first dual-homing device of MC-LAG, it broadcasts to Server B of the same VLAN on the one hand, and ServerB is single-homed to the MC.
- -LAG's first dual-homed device is another server in the same VLAN as ServerA. At the same time, it is forwarded from the first member port of MC-LAG to the same server ServerA. This ensures that the server ServerA finally receives only one BUM packet flow in both the uplink and the downlink.
- step 113 the traffic is forwarded in a traditional manner.
- the processing scheme for traffic forwarding is as follows: For known unicast traffic, set MC- The member port of LAG is the synchronization interface of the application protocol.

The interface relies on the ICCP channel established on the LDP basis. Based on the needs, different synchronization information can be defined.
- the MC-LAG member port fails, point the synchronization interface of the application protocol to the peerlink interface to allow the upstream and downstream traffic paths to be inconsistent; for BUM packets, when all member ports of MC-LAG are normal, the peerlink has ports Isolation mechanism, that is, BUM packets received from the peerlink port are no longer forwarded to the MC-LAG member ports. If the MC-LAG member port fails, the port isolation mechanism of the peerlink is released and BUM packets are allowed to be forwarded to the MC-LAG member port.
