multi context / multi sub-ints -- route to single interface

Unanswered Question
Apr 16th, 2008

config is similar to multiple context using "shared interface".

Can multiple inside sub-interfaces (VLANS) route to a single interface on L3 switch? or does each sub-int need to route to a physical interface?

L3 vlans not config'd on core switch to keep lab pc's isolated from rest of network

Config attached for clarification

I have this problem too.

No you can't do this. Multiple vlans means multiple vlan interfaces on your L3 switch or you make the connection between your L3 switch and the inside interface of your ASA a L2 trunk link.
