Something to consider. Although the 3600 can support a HSSI port you need
to think about how much throughput will be going through the router. We had
a 3640 with about 80 BGP entries and about 50 lines of ACL on it with 128MB
of RAM. It had 10-12MB sustained throughput on one of its interfaces and it
would shut the interface down every few hours due to overflowing. Cisco
said that we could use it a little longer with 256MB of RAM but that the
3640 really just can't handle that much sustained throughput. Heck, it ran
60% cpu utilization all the time. IMHO, if you really need the T3 then the
3600 may not be the right router for the situation. We replaced the 3640
with a 7513 and it runs at 5% now. For all the T3s we get now we don't use
anything less than a 7000 series. Just my $.02
