n't imagine you could effectively perform stateful
inspection, access lists, maybe VPN services, and BGP for a 100Mb+ internet
connection on even a 5585. They just aren't that powerful.

trust the second isp to advertise the SWIP block correctly if
they are not a tier 1. Even though they may advertise it for you to their
upstream, they don't always have the appropriate procedures in place to get the
LOAs to the upstream so your block just gets filtered out.

IFRC, the 19xx and 18xx are slower than the new 89x series. We are
transitioning away from 18xx because of limitations on the platform that the

You question has many caveats. Just having two providers does not necessarily
get you more resiliency. If you have two providers and they are terminating on
the same router, then you still have a SPOF problem. You also need to look at
pysical paths as well. If you have two (or three) providers
