Hello Max

Yes, you can do this. Take a look at this post, which is in the DMVPN Phase 3 BGP Routing forum topic, but the same principle applies here too:

DMVPN Phase 3 BGP Routing

Hello Rcscullado It is possible to create a DMVPN topology where you have spoke routers assigned to different BGP AS’es. You can use the neighbor peer-group remote-as multiple times with different peer groups referencing different routers, and each one in a different AS. This configuration is fine if you have two, or five or even 10 spokes, but what if you have 500? It’s not that scalable. So in general, the rule of thumb for larger networks is to either use iBGP across all of your DMVPN to…

I hope this has been helpful!
