EIGRP wierd issue

[karthikeyan gopinathan]

Hi

my network is running completely with EIGRP . today  one particular layer 3 device went down and came backup automatically by itself. when i see the logs i found that only that particualy layer 3 device went down. everything else was connected. i dont know why it that particular device alone went down and came backup

below are the logs

Oct  6 13:57:19.889: %DUAL-5-NBRCHANGE: EIGRP-IPv4 1: Neighbor 172.22.11.5 (GigabitEthernet1/37) is down: Interface PEER-TERMINATION received

can anyone give me suggestions what may be the root cause

Hi

According to the message, it appears that the neighbor has terminated the connection (PEER-TERMINATION received)

have a look at the log in the neighboring router.
