We Just pulled a Maxxwave Vengence CHR from an edge router role. Had
some major major issues with iBGP route convergence with another x86
based mikrotik router where each router had a full table from an
upstream and they needed to synchronize between them. Even when we moved
the upstreams to all be on the Vengence and pulled out the full routes
downstream to reduce that convergence, it still was running out of CPU
at about 3.5 Gbps, causing packet loss under heavier network load times.
We went to Juniper. I am far from a routing expert but once you get into
multiple full table upstreams or > 2Gbps I would strongly look at real
routing hardware. Even a small ISP could lease one and it should be
affordable. It is probably the single most critical piece of your
infrastructure after all.

Decoupling forwarding and management tasks means that even if the
management side is swamped (i.e. processing BGP updates) it has no
affect on forwarding performance.
