Cisco DMVPN - EIGRP Neighbor Issue

Hi;

 

I have two Cisco 1921 Routers setup with a DMVPN. The tunnel comes up no problem and the routers exchange a new adjacency. However, the adjacency they form is for the tunnel network (172.16.0.0). On both routers, I have used the following network statements in the AS:

 

172.16.0.0 (tunnel interface)

x.x.x.x (local subnet)

 

The routers do not build an adjacency for each side's local subnet, only the the tunnel subnet. So communication obviously fails. If I create a static route on each router to route between local subnets, it only works from Spoke to Hub, not from Hub to spoke.

 

Why is EIGRP not forming the adjacency for the local subnet behind each router?

 

Thanks!

PM me please. We will setup a webex to review it together and put back on the forum what are our findings.

Thanks
