Problems solved by technology

[0004] However, when the DF device restarts in the EVPN multi-homing access network, the DF device will send a route withdrawal instruction to the neighbor VTEP device, so that the remote VTEP device (a VTEP device that is different from the DF device in the multi-homing network) revokes the DF device Synchronized forwarding list. At this time, the remote VTEP device cannot forward data packets to the VM.
At the same time, the DF device is re-elected from the neighbor VTEP devices in the same multi-homing network as the DF device. After the new DF device dynamically learns the MAC-IP address entry of the VM, it synchronizes the MAC-IP address entry IP address entry, the remote VTEP device generates a new forwarding list after receiving the new MAC-IP address entry synchronized by the DF device, and can continue to forward data packets to the VM according to the newly generated forwarding list, but the entire cycle consumes The time is long, resulting in serious loss of data packets

Abstract

The embodiment of the present invention relates to a routing processing method and device, including: receiving a multi-homing routing revocation instruction message sent by a second VTEP device as a DF device in a multi-homing network; When inside, re-elect the DF device in the multi-homing network according to the multi-homing routing revocation instruction message; Convert to the dynamically learned second MAC-IP address entry; send the first address synchronization message to all VTEP devices in the multi-homing network and the third VTEP device outside the multi-homing network. According to the routing processing method and device provided by the embodiments of the present invention, the problem of data packet loss during the restart of the second VTEP device as the DF device in the multi-homing network can be alleviated, and the transmission quality of the data packet can be improved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a route processing method and device. Background technique [0002] Ethernet Virtual Private Network (English: Ethernet Virtual Private Network, referred to as: EVPN) is a two-layer VPN technology. In order to improve the reliability of the access side, the protocol stipulates the EVPN multi-homing access network, thereby improving the reliability of service data packets. In the EVPN multi-homing access network, a virtual machine (English: Virtual Machine, referred to as: VM) can access different scalable virtual local area network tunnel endpoints (English: VXLAN Tunnel EndPoint, referred to as: VTEP) through multiple links at the same time. ) devices, different VTEP devices can back up each other and share loads. Multiple links connecting the VM to different VTEP devices form an Ethernet segment (English: Ethernet Segment, ES for short). An Ethernet Segment Id...
