一种通告路由的方法和网络设备
By identifying the number of interface switching in EVPN VPLS networking, obtaining ESI values, and advertising routes, traffic-balanced multicast forwarding is achieved during primary/standby UP switching, solving the packet loss problem caused by MAC migration and ensuring network stability.

AI Technical Summary
In EVPN VPLS networking, due to different PE devices being misconfigured with the same MAC address, the PEs continuously synchronize MAC address information, forming a loop, consuming link bandwidth, and causing unstable user traffic migration during fault recovery, resulting in packet loss.
When the number of interface switching attempts reaches a threshold, the system obtains the administrator-defined ESI value and sends it to the aggregation device and other Leaf devices via an announcement route. This enables balanced multicast forwarding of packets and ensures that no packets are lost during primary/standby UP switching.
It effectively solves the problem of forwarding failures of user traffic under MAC migration and migration suppression conditions, ensuring stable traffic transmission and avoiding packet loss.
