Dear All,
We have around 10 different locations and there is a full mesh connectivity between them, now I need to encrypt the traffic between these sites, now if i create a static tunnel between each locations then it will not be scalable so how can i achieve this, can i achive this by mGRE and DMVPN, but again this works fine in case of hub and spoke environment but in any to any kind of a scenario will it be useful.
Please help.

Not sure I actually posted this yesterday?
But the EIGRP configuration has been used for over three years and works well, note the EIGRP timers pushed out to what you see, it was because the defaults are too sensitive.
The OSPF is proving somewhat irksome; there are lots of OSPF adj changes in the logs, even with the timers adjusted.
