I'm planning on setting up a DMVPN (over the Internet) as a backup to our MPLS WAN connections. There will be a couple of sites with two MPLS (T1) connections and one Internet (DSL) connection.
I would like to load-balance (via GLBP)the MPLS traffic ,but failover to the Internet DMVPN (Cisco 800 series DSL router) in case both MPLS circuits fail.
Is it possible to load-share the two MPLS circuits but then fail-over to the DMVPN if the MPLS circuits fail? Could this be done via GLBP?
Thanks for the help.
