Maybe.  And maybe I'm using worst-case synthetic test sets in addition
to real routing sets.

And I'm unaware of Cisco 2600-class routers that handle anywhere close
to 10 Gbps.

Ideally the forwarding would be done with ASICs.  The Cisco asr1000
class router seems to be what I'm looking for.

Perhaps the OP can clarify whether his omission of these was accidental,
because such features were assumed, or because he does not need them.


I don't need any of that stuff, just BGP, OSPF and fast packet
forwarding for IPv4.  But the point is that I need only routing
functionality, I don't need switching functionality like on a Cisco
6500-class system.
