That’s actually config that will work with all Supervisors, wrong example :)

I understand Patrick is looking for a way to distinguish switched VLANs from
routed VLANs, and indeed VLANs can be reused to forward different traffic with
VLAN local significance on 6500/7600 starting from Sup2T.

For that (Patrick) needs bridge domains, so EVC infra - which is available
on Sup2T with all ports, even with classical “LAN” cards - no SIPs needed.

Config examples for different scenarios - google found it:
