I've trying to investigate a BGP flapping that showing different neighbors going down at different times.
It seems like there's something causing the link to go down but I cannot make any sense of the logs or what they are trying to tell me. I'm going to post the logs from today where the BGP peers flapped several times.
If anyone can point me in the right direction or give me some insight as to what's causing these flaps I'd greatly appreciate it.
