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
