FRR nhrpd do not support multicasting over GRE tunnels so OSPF or EIGRP don't work since they use multicast addresses to discover neighbors

As i remember the lack of multicast replication was the reason this stopped up last time it was discussed... And as ospf and eigrp is the most used protocols run over dmvpn i think this is a showstopper for implementimg nhrpd

Perhaps I'm one of the minority. but BGP is our predominant DMVPN routing protocol.

@hammerstud that would work for you - but it will break everyone elses implementation ;)
