EIGRP Interface PEER-TERMINATION received

[Juicz17]

Dear All,

Kindly assist with EST: %DUAL-5-NBRCHANGE: EIGRP-IPv4 16600: Neighbor 192.168.2.53 (Port-channel2) is down: Interface PEER-TERMINATION received. This happens every day between 7 pm - 8:30 pm then become stable. When it happens internet connectivity becomes unstable and I have to go into the server room physically.

between 7 pm - 8:30 pm   << this case i would investigate what is happening that time in the network.

is the network fully utilized  or do you have any CPU process high, many reason, enable debug or collect some logs to verify what is wrong on that time

check any errors on Port-channel (is this L3 port-channel ?), also put monitoring on this IP  192.168.2.53 to verify you have connection available 100%

To me the most significant part of the message is this "Interface PEER-TERMINATION received"  . Your EIGRP neighbor took down the neighbor relationship and sent you a notification about it. What is going on with that neighbor?

HTH
