Abstract

The invention provides an MAC (Media Access Control) route updating method, equipment and system, and belongs to the technical field of networks. In the scheme provided by the invention, after a first network device updates an MAC table item according to an MAC address of a target device learned from a second network device, a message including indication information can be sent to a third network device so as to indicate the third network device to delete a first MAC route stored in the third network device. Since the MAC table entry before updating is obtained by the first network device according to the first MAC route, the first network device instructs the third network device to delete the first MAC route after updating the MAC table entry, and it can be ensured that the third network device can send the MAC route of the MAC address to the first network device again after learning the MAC address again. Therefore, it can be ensured that the first network device can update the MAC table item corresponding to the MAC address in time based on the MAC route which is sent again.

Description

technical field [0001] The present application relates to the field of network technology, and in particular to a method, device and system for updating a media access control (media access control, MAC) route. Background technique [0002] During the evolution process from a virtual private LAN service (VPLS) network to an Ethernet virtual private network (Ethernet virtual private network, EVPN) network, a networking state in which EVPN and VPLS coexist will appear. In a network where EVPN and VPLS coexist, a provider edge (provider edge, PE) device that is deployed with both a VPLS instance and an EVPN instance may also be called a converged PE device. The VPLS service can be carried between the converged PE device and the first PE device deployed with the VPLS instance, and the EVPN service can be carried between the converged PE device and the second PE deployed with the EVPN instance. In the scenario where EVPN and VPLS coexist, the traffic of the VPLS service and the ...
