DMVPN over multi area OSPF

HannyKhasawneh · ‎10-07-2009

We have single ospf area running over DMVPN and the number of branches keep increasing , I need help to divide ospf to muli-areas, our IP address allocated to branch offices are designed according to geographic locations.

I have the exact same issue... Did you find a way to configure this ?

Although there is an excelent white paper on DMVPN here, I don't see how you can have multiple mGRE tunnels at the hub. Perhaps with the "tunnel protection....shared. The shared keyword indicates that mutiple mGRE interfaces will use the IPSec encryption with the same source IP address".

Thank you.
