Hi, I've deployed Dynamic Multipoint VPN (DMVPN) technology with one Hub (7206VXR GP2) and one Spoke (C2801) each one have a Tunnel0 interface and use EIGRP to pass route back and forth⦠When the DMVPN interfaces were configured and NHRP registration occurred, all looked good but within 10 sec, randomly it down and up again, the output console logs indication of failure is the EIGRP neighbor down. Can someone help me? I've done everything but the problem steel remaining. Thanks

I'm sorry for the inconvenience, but I have resolved the problem creating a new EIGRP autonomous system on Hub and adding a network using wild card mask.
router eigrp 100
redistribute static
network 10.0.0.0
network 172.31.0.0
no auto-summary
### new router autonomous system ####
router eigrp 90
network 10.0.0.0 0.0.0.255
no auto-summary
Other trouble that I had was that RDP (think client) on the âspokeâ side can't connect to a RDP Server. I've corrected it modifying the MTU and mss values.
Interface Tunnel0
ip mtu 1372
ip tpc adjust-mss 1332
Once again, thanks for answer me..
