The log buffer of the NE5000E reports BGP peer down.
It is found out that after the interface POS 5/0/0 becomes Down, the next hop of one of the equal-cost routes is interface NULL0.
After POS 5/0/0 of the NE5000E is Down, the routes to the public network and the status of the corresponding BGP neighbors are as follows:
Before the interface POS 5/0/0 is Down, the routes to the public network are as follows:
[M-NN-LANGDONG-R-NE5000E-01]DISP IP ROU 188.8.131.52
Routing Table : Public
Summary Count : 2
Destination/Mask Proto Pre Cost NextHop Interface
BGP 100 0 10.0.0.1 Pos5/0/0
In VRPv5.3, the route iteration is implemented as the preceding mechanism and is enable by default. In networking, we must analyze whether route iteration can cause results that are not expected.
