If the amount of paths are under 40,000, you can take full routing
tables from two providers. The problem comes into play when one link dies. A
68030 can't handle it. Oh, and by taking full routes, your cpu on a 2500 goes
to about 97%

And if you have the other routers, 32 megs is just fine for now.

cisco 4700 (R4K) processor (revision B) with 32768K/4096K bytes of memory

BGP table version is 3280358, main routing table version 3280358
41880 network entries (83195/83826 paths) using 7282924 bytes of memory
6719 BGP path attribute entries using 783464 bytes of memory
3206 BGP route-map cache entries using 51296 bytes of memory
8414 BGP filter-list cache entries using 134624 bytes of memory
Dampening enabled. 546 history paths, 214 dampened paths

And we are seeing 41,880 network entries with just 32megs with free
memory with enough free memory

So you are only going to have it in the PM3? What CPU is in the PM3?
How much memory can it handle?

Thanks, now back to livingtson......
