DMVPN after NHRP resolution
in this nice post: http://blog.ine.com/2008/08/02/dmvpn-explained/
I am qouting this part:
At this point, R2 receives the original data packet from R3 (ICMP echo) and tries to send a response back. The problem is that the destination IP address for the echo reply is “10.0.3.3” and the next-hop is “10.0.0.3”, which has “glean” CEF adjacency. Again, R2 replies back across the hub and send a Resolution Request packet: first, directly R3 – this attempt fails – then it sends the resolution request to the NHS.
the question is if NHRP was ARP-like protocol, then after R3 resolve the real IP address of of R2 and send first ping echo packet, R2 has to requets from the Hub the real IP of R3 (through NHRP resolution request), but is not this address included in the packet received from R3 (source address) !?
in ARP the sender put its MAC address as the L2 source, then the recived will use it as L2 destination.
