Background technique

With the development of the Internet, people are increasingly demanding network reliability. For example, taking a local area network as an example, it is very important for LAN users to be able to keep in touch with the external network at all times.

Generally, all hosts in the LAN internal network set an identical default route to the egress gateway to implement communication between the host and the external network. When the egress gateway fails, communication between the host and the external network is interrupted. Therefore, configuring multiple egress gateways is a common method to improve system reliability. When one of the egress gateways has a problem, it will quickly switch to another egress gateway. To ensure the user's access to the external network. The implementation of the above-mentioned system to improve the reliability of the system introduces another problem, that is, the switching between the egress gateways, and the protocol for processing the two-layer redundancy switching in the related art, for example, the virtual router redundancy protocol (Virtual Router Redundancy Protocol, referred to as: VRRP)+Multiple Spanning Tree Protocol (MSTP), or VRRP+Bidirectional Forwarding Detection (BFD) protocol.

The network in this embodiment may be a local area network or other network. The Layer 2 redundancy system of the device can work normally. It can be divided into Layer 2 redundancy protocol, path detection protocol, and MAC or ARP learning. For example, the Layer 2 redundancy protocol is used to handle redundancy detection. With the active/standby switchover, the link detection can be used to quickly detect the link status and notify the redundancy protocol processing module to perform fast switching. After the port is switched, the MAC address or the corresponding ARP processing is re-learned on the backup port. The main implementation manner of the handover method of the redundant port provided by the embodiment of the present invention is the processing of the MAC or ARP learning part.

The key fields include but are not limited to the instance number, the VLAN, the redundant port list, the main port number, and the data specified by the command line. The callback function that is sent is switched, and the corresponding processing function is hooked according to the information configured by the client. When the redundant port data is switched, the callback is called to complete the deletion of the related data. For example, to modify the MAC table, you can attach the MAC maintenance processing function provided by the MAC module. According to the command line configuration, it is determined whether to listen to the protocol packet or synchronize the current device entry. Listens to the protocol packets before and after the master and backup, and parses the key fields in the packets and writes them to the database.

The uplink port of the Layer 2 access device D includes: port1_2, port2_2, port3_2, and the entry on the redundant switching port or the received packet on the Layer 2 access device D. After the file is parsed, it is saved to the fast switch database. Because device A, device B and device C are redundant, only one device is the master device and can be connected to the external network. When the redundancy protocol finds that there is a problem with the link and needs to perform link switching, the BFD can discover the link problem within a few milliseconds. The selected new master device sends a switch message to the Layer 2 access device D. Finally, Device D clears the information of the other two ports, and then restores the redundant information of the backup from the database to the new primary port.
