I have a 3800 series router with a DS3 interface that will be terminating my DIA. One G1 interface will connect to my ASA. I need to configure this 3800 router into a vircual router so that I can use two other Gi interfaces to serve as a router in front of my ASA. This is referenced as Cisco's version of the Netscreen Virtualization.
Normally, you would have an outside router to terminate the LEC Inetrnet circuit, a firewall, then an inside router. I need to double up and use one router as the outside and inside router.
Does anyone have any reference on how to set this up?
