Hi! I am having some trouble with EIGRP adjacency flapping over my DMVPN network.
*Dec 5 12:55:29.412: %DUAL-5-NBRCHANGE: EIGRP-IPv4 1: Neighbor 192.168.0.5 (Tunnel0) is down: retry limit exceeded
*Dec 5 12:55:32.919: %DUAL-5-NBRCHANGE: EIGRP-IPv4 1: Neighbor 192.168.0.5 (Tunnel0) is up: new adjacency

I am not getting the HUBs loopback (5.5.5.5/32) on R1 and vice-versa in the routing tables either.
1.0.0.0/32 is subnetted, 1 subnets
C 1.1.1.1 is directly connected, Loopback0
10.0.0.0/8 is variably subnetted, 4 subnets, 2 masks
C 10.10.1.0/24 is directly connected, GigabitEthernet0/0
L 10.10.1.1/32 is directly connected, GigabitEthernet0/0
D 10.20.1.0/24 [90/3072] via 10.10.1.2, 00:20:58, GigabitEthernet0/0
D 10.50.1.0/24 [90/3072] via 10.10.1.2, 00:20:58, GigabitEthernet0/0
192.168.0.0/24 is variably subnetted, 2 subnets, 2 masks
C 192.168.0.0/24 is directly connected, Tunnel0
L 192.168.0.1/32 is directly connected, Tunnel0
