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

[Derick Winkworth]

There are virtual-switches on Juniper MXs which do precisely what you are asking 
for.  Each virtual-switch has the entire VLAN space and their own spanning-tree 
configuration.

Could something like the UNI/NNI port types that are used on ME-switches
like the ME3400 be a possibility? If you have a switch with several
ports configured as UNI ports in the same VLAN, they won't be able to
talk to each other, even though they are in the same VLAN. All traffic
is required to go out via NNI uplink ports ... (not sure whether this
feature is available on the 6500 series though)
