We are building a Multiple DMVPN Clouds. These are 2 single hub DMVPN clouds and 1 dual hub DMVPN cloud. The dual hub VPN cloud is in a seperate VRF as the other 2 singles.
For both single- and the dual- hub DMVPN cloud we use EIGRP as our routing protocol. We have first configured the 2 single DMVPN Clouds with EIGRP and the work fine. All routes are displayed correctly.
When we use the "address-family ipv4 vrf DUALHUB" command within EIGRP to configure the networks for the VRF, we see the adjaceny popup but no hello's are exchanged. Finally the Spoke drops the adjencency and immediately builds one up again.
Why the 'normal' non VRF DMVPN tunnels work fine and the Dual Hub Tunnel does not, is beyond me. Does anyone have similar problems.
We are running on 4x2851 - 12.4.24T2(ED) for the Hubs and 12.4.24T2(ED) on a 1841.
