In DMVPN Phase 3, I need to deny Spokes to reach each other, except a certain Spoke I will name it here SPOKE-X.
I need all the Spokes to communicate with SPOKE-X, but all the Spokes must not communicate with each other.
With DMVPN Phase 1, the answer is turn of split-horizon on tunnel interface and to use Distribute-List in the EIGRP (My interior routing protocols).
I will upgrade My DMVPN to Phase 3, to Save the Bandwidth on the HUB for the Traffic from Spokes to SPOKE-X
I need your help please.
