I’m going to be setting up over a dozen new ASA5510s in front of preexisting 2821 routers. I currently have EIGRP running in GRE tunnels between the sites.

I have heard that the ASAs do not support GRE tunnels…yet you need a GRE tunnel for EIGRP to work because of the multicast hellos.

What do you think is the best solution to the problem? I was thinking perhaps the EIGRP neighbor command could help me because of the fact that it sends unicast to static neighbors instead of multicast and I could get around the fact that I don’t have a GRE tunnel.

This has been dogging me for a while and I would really appreciate any help you could provide. Thank you,
