DMVPN spoke to spoke connection

[mahesh18]

Hi Everyone,

Need to confirm on DMVPN say  if R1 is hub and R2 and R3 are spoke.

IF R2 need to talk to R3 it will use NHRP and will go to R3 via  R1 ?

Is there any way that R2 can talk to R3 directly using NHRP?

Regards

You mix some functionalities here:

NHRP is used in DMVPN to register the spokes on the hub and give them the possibility to ask the hub for actual spoke-addresses. With that, NHRP is always between the spokes and the hub. just see this as control-traffic. There is no need to takl spoke-to-spoke here.

When the spoke is aware of the public IP of a different spoke it want's to talk to, then the IPSec-connection is buid directly between the spokes.
