Hi,

So you'll not use anything BGP based, then?

(Upstreams going down usually lead to transient loops and ICMP unreachables,
and those usually kill TCP sessions, at least if Windows stacks are 
involved)

Dual-/48 + shim6 actually reconverges *faster* on outage than anything
BGP based.  Just sayin'
