Is it possible to create a neighbor relationship between an ASA and a router on the external interface? I would like to have the ASA receive the default route from our external DS3 router so that I can reroute to our secondary provider should an outage occur.
I worked on this last night for a couple of hours with no luck and can't find any documentation showing the solution. I went as far as statically configuring neighbor relationships, allowing eigrp on the ACL attached to the Outside interface etc and had no luck. The ASA does not appear to send any EIGRP traffic out the external interface. Any suggestions? Anyone done this?
