2 circuits failover????

Unanswered Question

Can you guys tell me what is the best way to set this up.

We have 2 circuits connected to our DMVPN router.

a) Primary circuit is used for DMVPN/internet browsing (38.99.x.x on port gi0/1)

b) secondary circuit will be used for internet browsing should primary goes down. (206.191.x.x on port fa0/0/0).

I am not sure how to configure it so when the primary fails the secondary circuit will allow internet browsing only.

I configured the tunnels etc to use the primary circuit.

Any suggestions?

Hello Kimraj,

if the second circuit is not to be used to provide access to the intranet via a second DMVPN cloud; all you need is a floating static route that will not used until better (with lower AD) default routes exist either received in the DMVPN or pointing to primary circuit.


ip route 206.191.x.y 201

this should be enough.

You probably need to configure NAT to provide internet access.

Hope to help
