Cisco – Configuring Dynamic Multipoint Virtual Private Networks DMVPN
DMVPN KB ID 0000954 Problem A while back I uploaded a run through on how to deploy GRE tunnels and protect those tunnels with IPsec. That point-to-point GRE tunnel is a good solution, but if you have a lot of sites it’s not a solution that scales very well.
