Hi All ,
Does any body done following thing either on lab or on a production network.
DMVPN with hub configured for GRE Multipoint and Spoke configured as P2P gre tunnel.
I did refer to some of the Cisco documentation , it did say this is possible . However I am not able to make it work . Any help on this front will be very very helpful.
THanks and Regards
Arun

Arun,
Because mGRE reflects NBMA network, NHRP must be configured on Spokes so the HUB has the Logical->Physical mappings for them. Use static mappings to solve it. The Hub needs “ip nhrp map multicast dynamic” so it would know how to proceed with packets it does not have a mapping for.

Hi All ,
I got this working. It was simple mistake that gave me all the pain.
I have not configured NHS details on the P2P GRE spokes and hence the Spoke was not registering the IP address to the hub.
Its all sorted now. Thanks very much for helping me with this.
Thanks and Regards
Arun
