You manage a single-hub DMVPN deployment with EIGRP running over the mGRE tunnels. Spokes register successfully with the hub, and spoke-to-hub and hub-to-spoke traffic works fine. However, you want spoke-to-spoke traffic to be forwarded directly between spokes instead of always transiting the hub, while keeping the hub's routing table summarized. Traffic between two spokes currently always passes through the hub. Which combination of NHRP configuration commands enables the desired direct spoke-to-spoke forwarding in this Phase 3 design?
