DMVPN: Multiple physical interfaces on spoke

[eirikalim]

Hi,

I have a scenario were i have to implement a solution which allows for dual ISP redundancy on spoke into dual hubs in a dmvpn environment.

I have created two tunnel interfaces, both have tunnel source set at each respective physical interface, the problem is that i can only have one tunnel active at any time, the other will never get past ike phase one and vice versa.

If i source both tunnels from one of the physical interfaces, both tunnels comes up, no problem.

I have tried using different vrf´s for each tunnel and corresponding phy. Interface. 

Any known limitations using 2 physical interfaces in an active/active role at the spoke site?

Both hub and spoke running same Denali 16.3.7 release.

Kind regards,

Eirik

Hi

I understand that tunnel source is different in both Tunnels. What about the destination hub? Do they terminate to the same hub?

Can you share your config please?
