Policy Based Routing in vrf on Cat6500 Sup720

We are utilizing PBR on SVIs that are in a vrf on cat6500/Sup720B. An route-map with an acl like "<ip-net> to any" is configured and a match sets ip next-hop to a gateway on a directly connected network. This works most times fine and we can send traffic from specified source addresses to a different next-hop than the routing table dictates.

But we now suspects that this traffic is cpu-proccessed since the cpu is rather high on the Sup720.

The questions are: Are PBR in a vrf CPU-processed? Any improvements to be done on PBR in vrfs?

Re: Policy Based Routing in vrf on Cat6500 Sup720

I think when the TCAM is running out of space, VRF processing is changed from hardware to software.

This Can increase the CPU utilization.

A IPSec VPN Services Module is recommended, or tuning the ACL of the PBR can improve the situation.
