BGP keepalive/hold timers are configurable even down to granularity of link or PVC level keepalives, but for session stability reasons, it appears that most ISPs at GigE exchanges choose not to tweak them down from the defaults. IIRC, Juniper is 30/90 and Cisco is 60/180. My gut feel was that even something like 10/30 would be reasonable, but nobody seems compelled that this is much of an issue.

Endpoint liveness. A IPv4 host on a VLAN has no idea if the guy on the "other end" died until the BGP timer expires. FR has LMI, ATM has OAM. (and ILMI) Pete
