GMT: %BGP-5-ADJCHANGE: neighbor xxx.xxx.xxx.xxx Down Interface flap

[guildwars1987]

Ever since we have established communications in our area we have had an issue with the BGP Neighbor Flapping. We have "bump" our crypto device to get the neighbor to combe back up.

Error when it went down
Apr 3 10:00:56.691 GMT: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/2/0, changed state to down
Apr 3 10:00:56.691 GMT: BGP: xxx.xxx.xxx.xxx resetting - interface Serial0/2/0 down
Apr 3 10:00:56.691 GMT: BGPNSF state: xxx.xxx.xxx.xxx went from nsf_not_active to nsf_not_active
Apr 3 10:00:56.691 GMT: BGP: xxx.xxx.xxx.xxx went from Established to Idle
Apr 3 10:00:56.691 GMT: %BGP-5-ADJCHANGE: neighbor xxx.xxx.xxx.xxx Down Interface flap
Apr 3 10:00:56.691 GMT: BGP: xxx.xxx.xxx.xxx closingshow int s0/2/0

This is where we then "bump" the crypto device.
