Description

60kv4 + 60kv6 route------>A------>B
There are two physical ports Ethernet58 and Ethernet122 between A and B. Ethernet58 is added to Vlan101 to Vlan132, and Ethernet122 is added to Vlan133 to Vlan164.

Each vlan is configured with a v4 address and a v6 address。
Create 64 v4 peers and 64 v6 peers.
64k v4 routes and 64k v6 routes are poured into device A and published to device B through 64 peers.
Ethernet58 remains up. Then Ethernet122 is shut down first and then starts up again after a while.

Shut down port 122 on device A, and then startup

Expected behavior

32 peers related to Ethernet122 can be established quickly

Actual behavior

The 32 peers related to Ethernet 122 are established while learning routing. As a result, it takes 3 minutes for some peers to be established.
