[c-nsp] VRF-ish solution for L2 interfaces?

[randal k]

NSP'ers,

For unfortunate reasons I am asking the collective if there is a way to do
VRF-lite style segragation for layer-2 interfaces. Situation is that I have
a 6509, and I need to make a single blade on the chassis have a completely
separate VLAN database from the rest of the chassis, effectively letting me
use a VLAN twice on the chassis without allowing them to talk to each other.

I dig that this can be done with protected ports or PVLANs, but am hoping
for a more "assign all the ports to a new VRF"-style solution.

Thanks in advance!
