I am having a problem with a DMVPN tunnel I recently created. I have done some torubleshooting on this and discovered the tunnel to be up between both sites, but they are not passing any traffic between each other. To create this tunnel I used code from a working tunnel and modified for the needs of this new tunnel. In my research i have not found a configuration example similar to what is configured on my routers. I feel like the problem is with either EIGRP or an access list
Here is the config of the spoke router (Cisco 1921 Running 15.4) that is not passing traffic over the tunnel, internet works.
interface Tunnel0
bandwidth 10000
ip unnumbered GigabitEthernet0/1
tunnel source Cellular0/0/0
tunnel mode ipsec ipv4
tunnel destination (IP Removed)
tunnel path-mtu-discovery
tunnel protection ipsec profile Mesh-VPN
router eigrp 1
network 192.168.154.0
passive-interface default
no passive-interface Tunnel0
Here are the results of the show commands EIGRP neighbor and ip access-lists on the Spoke Router that is not passing Traffic
