What's the BCP for BGP timers at exchange points?
I imagine if everyone did something low like 5-15 rather than the default
60-180, CPU usage increase could be significant given a high number peers.
Keeping in mind that "bgp fast-external-failover" is of no use at an
exchange since the fabric is likely to stay up when a peer has gone down,
and BFD would need to be negotiated peer-by-peer, is there a
recommendation other than the default 60-180?
Would going below 60-180 without first discussing it with your peers, tend
to piss them off?
Chris
