We have a 7200 router with the VAM2+ card, and one functional GRE/IPSec DMVPN tunnel. We are trying to create another one since these are in an MPLS environment and cant be shared between customers.
I believe I may have the answer to my problem, but I need verification before proceeding. The new tunnel created appears to be accepting phase 1 & 2, tunnel comes up, and I see inbound packets, no returns. When I do a show crypto ipsec sa peer for the tunnel in question, the crypto map is the other tunnel.
crypto map: Tunnel199-head-0
I should be seeing this
Crypto map tag: Tunnel300-head-0,
First can there be multiple DMVPN tunnels on one core router, and second, if so, does each one require s separate IP address to work?
