DMVPN OVER MPLS

[mandeep62]

Hello Everyone,

I'm trying to understand DMVPN over MPLS network. I have attached a topology where I want to use DMVPN as a backup when MPLS goes down. What would I need to implement on HQ and Branch routers so that they would connect using DMVPN if MPLS goes down. Considering, HQ and BRANCH is connected to internet as well.

You need IPSLA to track the connection, if the primary go down then the secondary route become active and route the traffic automatically use secondary route.

Below Example documentation help you to understand more.
