DMVPN Single Hub failover

[rawiramdhan]

Hi All,

I have my hub (HQ) and spoke (RO) network. My RO has several WAN links which are extremely unreliable. I get an IP-address via DHCP on those interfaces and I'm behind a NAT.

However I would like to monitor the devices in my RO so DMVPN would be a good sollution. When I configure my DMVPN I cant specify my source address/interface because I have multiple and those might be non-routable addresses.

How can I solve this? Is it possible to solve? If not, is it possible to solve when all my WAN addresses are routable (still behind NAT and DHCP).

I did some research and if i'm corrent there are three ways to solve this issue;

1: Multiple tunnels (one for each uplink).

2: Interface state tracking

3: Something with vrf or nhrp

If someone could push me in the right direction It would be much appreciated.
