Having spent the day chasing something identical.....for us is was that the traffic was being redirected to another router on the inbound VLAN - every packet needing a redirect gets punted. A few changes to topology and the redirect requirement was removed and the traffic returned to being hardware routed.
We also had span the RP before we worked out why the traffic was being punted.

Howdy, I've been having some issues with queue drops/CLI sluggishness on a 6500 and I wanted to check what kind of volume of traffic I was getting punted to the RP. I made a span session and began checking out the traffic with tethereal. It seems like a huge (30,000) or so packets every few seconds of just UDP traffic is being punted. The system is a Sup720-3BXL. Does anyone know how to determine what kind of traffic should be punted to the RP and more importantly why this UDP traffic is hitting the RP? It almost looks like p2p traffic, but I also see other types of traffic, tcp 445, DNS, port 80, etc. thanks, -Drew _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
