Hello, I'm working on an issue with a customer failing to failover from MPLS to their DMVPN cloud. It's a single router that has both an MPLS and internet connection. On the MPLS line they're running BGP and on the DMVPN tunnels they're running EIGRP.
For some reason the routes between the spokes are being exchanged. DMVPN is running is phase 3 and here's the config for the hub and the 2 spokes. Can you please take and look to see if I'm missing anything. Thank you so much.
