iBGP over DMVPN - question on neighbor peer

Hi All,

I have a question regarding using iBGP in my core and solitary routing in a hub and spoke network that uses DMVPN's.  I constructed a lab, which I'll sketch out below:

Hub Router (iBGP 65000 & DMVPN Tu1 simulating ISP cloud (static routing)-------Spoke Router (iBGP 65000 & DMVPN tu1

Now, what I want to do is set the neighbor statements in the BGP configs on both hub and spoke routers to the tunnel addresses of each's peer:


router bgp 65000

neighbor remote-as 65000

network mask


router bgp 65000

neighbor remote-as 65000


Now, assuming my DMVPN configs are correct, (and they are, because I tested the tunnel before implementing the BGP test), I would think the tunnel would establish, essentially making the devices appear to be one hop away from each other, and the tunnel IP's would form the BGP neighborship.

However, I could not get this to work, and I am guessing it is because you can't BGP peer a virtual interface to a virtual interface if your routers are not physically adjacent.

Is this correct? Does the BGP peering have to be done between routers that are physically next to each other from a layer 3 perspective?
