RE: [isp-bgp] fast backup for BGP

["Darrell Hyde" <DHyde@...>]

I'm actually doing the same thing. I have 2 7206 VXR's, each with its own Internet transit links, and a direct connection between them. They each peer BGP with their providers and with each other. This way I can take advantage of all of my providers no matter which router is the active member. The hiccup you're seeing might be because you have your timers set too high. I have mine set to 5 second intervals with a 15 second holdtime and my transitions are always quite smooth (while pushing 100 or so mb/s to the net no less). Setting each member to preempt is also key to having smooth transitions. We've even taken the fire problem into account as well (well sorta) by putting our routers at physically diverse points in our datacenter. This has at times made wiring and troubleshooting cumbersome however.
