Hello @jewfcb001 

Restrictions are depended upon the various things like the IOS version you are running on 6500 and SUP engine etc. For example:

According to the below document, On Cisco IOS Release 15.0SY has the following restrictions:

Policy Based Routing (PBR) (cisco.com)

The PFC and any DFCs provide the hardware support for the following:
• These IPv4 PBR commands:
– match ip address
– match length
– set ip next-hop (2,000 instances)
– set ip default next-hop
– set interface null0
– set default interface null0
– set ip vrf
– set ip default vrf
• If the RP address falls within the range of a PBR ACL, traffic addressed to the RP is policy routed in hardware instead of being forwarded to the RP. To prevent policy routing of traffic addressed to the RP, configure PBR ACLs to deny traffic addressed to the RP.
• Local PBR.
• IPv4 PBR recursive next-hop with load balancing.
• IPv6 PBR is supported in software.
• IPv6 PBR recursive next-hop is not supported.
Note: IPv4 PBR recursive next-hop with reload balancing is not supported on Supervisor Engine 720.
Note: Local PBR does not support routing of distributed Netflow Data Export
