I set up DMVPN using a 7600 with VPN SPA as the hub router. I used crypto-connect mode on the 7600 with tunnel protection on the Hub MGRE and also tunnel protection at the spoke GRE. There is a static route to the outside interface that points to the provider while the tunnel ip and the lan addree is advertised into EIGRP. The ipsec is up and shows so but the EIGRP neighborship is down. What can be the problem. The remte site uses a 2811 router and the DMVPN Design is hub and spoke.
