IPv6 PBR on Catalyst 6500
The lesson of the day is: Better avoid IPv6 PBR on Cisco Catalyst 6500. It will be handled in software on Sup720/VSS720 if you assign a policy route-map to a Switch Virtual Interface (SVI) according to the documentation. Which only leaves routed ports as ones where hardware switching is supposed to happen. L3 VLAN interfaces and sub-interfaces are both SVIs and hence all IPv6 traffic that matches the PBR rules will be punted to the RP. The Sup2T supervisor does not support IPv6 PBR at all at this time.
