Re: OT-How many IPV4 routes Cisco 3900 can handle?

Well that's different. For one your traffic pattern's probably won't grow
that large. I'm still not sure I understand exactly why you need full
tables though. For example your other ISP could only advertise you the
routes you need. You could also allow them to send you the full table and
filter so if you want more all you have to do is update your filters. I
wonder if any carriers are willing to do ORF? I guess it's moot though.
When I referred to bw and throughput running out I was talking about
growth. There is enough memory to support the full table and growth so
the ceiling the original poster should be worried about is the circuit or
LAN throughput since the 3800/3900 are mainly DS3 routers.

Redundant ISP connection and I want to route traffic to a couple specific
AS
numbers out the other link (for remote management purposes).
