In order to multi-home effectively you need to have the full routing table
on your router. Last time I looked the full routing table takes up 40MB
of RAM. I don't even think the PM-3 can support that much RAM. The CPU
can probably handle it though.

We have a Cisco 7010 with 64MB RAM, it uses a 68040 CPU. I don't have my
second T1 installed yet so I'm not running BGP yet. This machine will
definately handle it.
