Trying to configure DMVPN as redundant link, A hub with four SPOKE,Wireless is the primary link and DMVPN is configured over ADSL link for redundancy,such that when the primary wireless link goes down EIGRP should select the alternate link and data traffic should flow through ADSL/VPN GRE tunnel
The issue is when the wirelss link is teared down, the SPOKE route goes down and can't reach the SPOKE, ADSL is a P2P interface with /30 IP address,
I missed the tunnel config while copy+paste, attached the complete config of hub & spoke, still no luck, i could not understand why the tunnel interface goes down when wireless link is dropped. though the tunnel source interface is BVI which is bridged to ATM0/0/0(DSL) interface
