Tiered DMVPN

[depadua_chris]

Can anyone help me find a configuration example of a two tiered dmvpn network?

I've attached a picture of what I'm looking for so that it's clear. I was able to find several documents that say that this is possible but none that will give me a configuration example. I'd like to know if the tiers are accomplished through seperate dmvpn networks (two Tunnel interfaces at the regional level) or through route manipulation.

Any help would be greatly appreciated!

The dual tier architecture does not allow tunnel profiles to be implemented. The crypto configurations on the branch require manual mapping to both possible crypto head ends.
