Newbie here so trying to understand some of this vpn features.
I currently have 2 WAN site (SJ and NJ) which have a /30 address ptp Router(with AIM) VPN to each other in case our WAN goes down. The routers are behind a ASA-FW with static NAT.
We will be adding a 3rd WAN site (London) that has similar topology (Router w/VPN-AIM) and a ASA and I was wondering what would be the best design.
I was reading up on DMVPN/mGRE and wonder if I should migrate to DMVPN or do I just setup a full mesh ptp btwn SJ,NJ, and London.
