Well, me changing the keepalives to 'keepalive 3' seems to shorten the
time in which the interfaces times out to the time it pings ok. What we've
noticed today is that we had an issue with eBGP and the link between the two
sites were fine. As soon as I fixed the eBGP to our carrier, the link went
sporatically bad again. Now I'm not a BGP guru so if anyone could help,
I'd appreciate it.
