I have 9 6500+SUP720-3BXL boxes with a mix of CFCs & DFCs running 
ADVIPSERVICESK9_WAN-M 12.2(33)SXI1, 12.2(33)SXI4a, & 12.2(33)SXI5 doing BGP, 
IS-IS, & OSPF for IPv4 & IPv6 with good results except:
    o  uRPF for IPv6 kills the CPU; do ACLs instead
    o  RA guard at 12.2(33)SXI4a seems broken;  I haven't tried it in anything
