No BGP, Yes OSPF, Yes ACLs, Yes CEF, Yes PIM,

Let me know what else you want.

So in my case, I don't quantify it's performance in terms of bandwidth, but rather in terms of the volume of packets. I would see it die at or above 50k PPS forwarding through two interfaces. I now use line-rate devices (ASR1002's) in this role and the 7200/7300 series are on the test rack.
