re: sub-interfaces - VLAN - Multiple contexts.

Ok so here is the scenario.

1) create 3 sub-interfaces on a physical interface.

2) create a VLAN and assign the same VLAN to sub-interfaces.

3) create 3 contexts and assign them to sub-interface.

Unfortunately I cannot assign the same VLAN to the 3 sub-interfaces as in step 2).

Therefore I am looking for an alernative solution.

Thanks, gordon

It would appear that your alternative solution would be to use another device, based on the information you have provided.

Ok I have some alternative solutions:

The most cost effective although not standard is to use the management interface and implement VLAN bridging to overcome the conflict in step 2.
