With above configuration, only Branch1-Edge2 router sends traffic to Branch1-Edge1 router if the main route to MPLS fails (as only Edge2 has the default route to Edge1). Therefore we have to configure the TLOC Extension under subinterface ge0/2.704 of Branch1-Edge1 with the command "tloc-extension ge0/1". Note: We change the mtu to 1496 to accommodate for the dot1q tag.
