I believe what you're looking for is a way to load balance traffic to
your web servers. You also wish to achieve a degree of fault tolerance
in case one server goes down. If both servers have the same content and
the content is static, you could use a feature called DNS round-robin
which basically returns a list of IP addresses to a querying client for
any single hostname. If one server becomes unavailable the client can
use the other IP addresses given by the DNS server to access the same
site. There's no routing protocol involved here and I don't think it's
possible to do what you need using a routing protocol. The good thing
about DNS round-robin is that the IP addresses of the web servers could
be totally unrelated.
This seems to be more of an application specific need for fault
tolerance. If this is possible using a routing protocol I'd be happy if
someone pointed out the error of my ways. I'm always open to
suggestions.

Subject: BGP for 2 T1's to one LAN [7:7511]
We are trying to have the web servers in our LAN accessible to the
internet via 2 T1's from different providers -- more for redundancy than
load sharing, though that matters too. Currently we have 2 T1's, each
giving us a different set of IP addresses. That just lets us put some
sites on each T1 -- doesn't give us an ounce of redundancy.
I've been told that if we get a router with 2 WIC's that can speak BGP
(Cisco 2600 or better) that may solve our problem. I'm very new to
routing, so can someone answer some basic questions?
Is the idea with this solution that we will be running just one set of
IP addresses? And that, because of BGP on our router, either ISP will
be able to route traffic to that set of IPs on the T1 it provides?
Thanks in advance.
