Thanks for your information, but can you tell me if EIGRP or OSPF is supported to run across the VPN tunnel and passw routing updates. I currently have two ASA and we are running an IPSEc tunnel as our backup connection in case our metro e connection goes down.

IPsec VPN tunnel doesn't support multicast. So EIGRP appears not fit. OSPF has one mode p2p no-broadcast can work via VPN on ASA. see doc.

Could you post a brief summary of your ASA EIGRP configuration? It would be helpful to see the config of your interfaces (ASA side and switch/router side), and EIGRP statements. There are not many ASA-related examples to be found as this is a new capability on the ASA. Thanks!
