I'm having trouble with mgre configuration of a spoke using point-to-point gre and a hub router, EIGRP does not seem to work and does not show in routing table for r7 and have it ping to r12 through mgre. Note: There are other routes for Hub router at are also not working, but want to focus on int Tunnel0 for mgre. No static routes can be used, so I'm not sure why it's not working as I followed the guide from https://community.cisco.com/t5/security-knowledge-base/mgre/ta-p/3115315.
