Morning!
I have an OT question...
I have two 40mbps internet connections from the same ISP today, each one
runs into a 2921 router. I receive a default route via eBGP with ISP and
the two routers peer via iBGP with each other. I'm going to be dropping one
internet connection soon and picking up a second ISP, same bandwidth. We're
just doing this to diversify.
Question is: Would the 2921s have enough resources to accept full internet
tables from each ISP?
The way I look at it, each router would store the BGP table from the ISP,
and also store the table from its iBGP peer... with soft-reconfiguration
enabled, It then stores a second copy of each peer's updates. Basically
requiring the router to store the entire internet BGP table 4 times... Am I
looking at this correctly?

I know my current ISP has an option for them to advertise their originated
routes (core routes) and a default, so that would significantly decrease
the update size from that peer, but I don't know if my incoming ISP has
that option.

Routers are default hardware spec, 1g RAM, 256mb Flash
IOS 15.2(4)M3

Thoughts??
