Hello all !
I just want to know that can we use mGre with our legacy P2P Gre?
What if i configure mGre on the HUB side & P2P on the spoke side's of my network. Should it work?

Sample hub configuration:
interface Tunnel1
ip address 192.168.241.254 255.255.254.0
tunnel source a.b.c.d
tunnel mode gre multipoint
tunnel key xxx
ip nhrp authentication xxxx
ip nhrp map multicast dynamic
ip nhrp network-id xx
ip nhrp nhs 192.168.247.1
Sample spoke configuration:
interface Tunnel5
ip address 192.168.24x.xxx 255.255.254.0
tunnel source e.f.g.h
tunnel destination a.b.c.d
tunnel key xxx
ip nhrp authentication xxx
ip nhrp map 192.168.241.254 a.b.c.d
ip nhrp network-id xx
ip nhrp nhs 192.168.241.254
ip nhrp server-only

Yes, that is valid, for spoke to hub traffic.
All the tunnel interfaces need to be in the same subnet.

A bundle of thanks ! ! it worked !
just one thing, i dont think that the HUB should have the "ip nhrp nhs" command.. should it??
