Hey Community,
This KB article explains a frequent use case of configuring an MPLS to VPN failover using dynamic routing between a Head and a Branch office.
This document focuses on one Branch office as shown in the figure below, but it is also feasible for a full mesh topology of a distributed remote office environments as we implement OSPF and BGP. This document uses BGP and OSPF to trigger the failover between the MPLS and VPN, also a GRE tunnel is created between the HO and BO embedded inside an IPsec tunnel.
