Catalyst Supervisor Engine 32 PISA Cisco IOS Software Configuration Guide, Release 12.2ZY

Catalyst 6500 series switches do not support:
Integrated routing and bridging (IRB)
–
Concurrent routing and bridging (CRB)
–
– Remote source-route bridging (RSRB)
Use bridge groups on VLAN interfaces, sometimes called fall-back bridging, to bridge nonrouted
protocols. Bridge groups on VLAN interfaces are supported in software on the PISA.
Catalyst 6500 series switches do not support the IEEE bridging protocol for bridge groups.
Configure bridge groups to use the VLAN-bridge or the DEC spanning-tree protocol.
These features are supported on LAN port subinterfaces:
IPv4 unicast forwarding, including MPLS VPN
–
IPv4 multicast forwarding, including MPLS VPN
–
6PE
–
EoMPLS
–
