I have a question about ISR2821 as a BGP router. Here is the info,
We have a customer currently having one ISP (20MB) with ISR2821 as edge router running BGP accepting only default route from current ISP. They will soon bring up another 100MB link from 2nd ISP. To better utilize both links, I want to do load sharing using BGP attributes (local preference and as-path prepend). To realize this, I want ISP to advertise their directly connected customers (partial routes) plus a default route.
The question is "can ISR2821 handle this", will 2821 have high CPU utilization and memory issue?
As default, 2821 has 256MB memory.
Anyone had experience in a similar situation?
PS: I am considering ISR G2 for the 2nd BGP router, ASR 1000 series may be a budget issue.
