Our network setup looks like the following:-
ASA 5510 --->> E0/1 (1841 ISR) E0/0 --->> VLANS / Catalyst Switch
We've recently added ASAs to our network. Our intention is to setup a VPN tunnel to our branch office. The head office setup shown above has many VLANs on the E0/0 interface one of which is a voice VLAN that handles our VoIP phone system traffic.
When we setup the VPN tunnel, we want to have the voice VLAN available at the branch office.
How would I go about doing this?
Currently the E0/1 interface of the ISR is configured with the IP address 192.168.15.254. The ASA's IP address for the lan/inside interface is 192.168.15.250.
Would I need to configure the ISR's E0/1 interface for sub interfaces instead?
