I have mpls-vpn connection and internet connection from same service provider.Both links are terminated on the same router.
Inerface hand off is Ethernet in both cases
Now I want to configure a seperate Internet access using same vpn last mile but which should act as a back up for my existing internet connection.Service provider can deliver internet and mpls vpn using same last mile(different VLAN+VRF configuration).What are the configuration changes need to be done for this set up.
do i need to run dynamic routing protocol to configure fail over?
you can use two default static routes ( if you are using it already ) but with IPSLA tracking
ip route 0.0.0.0 0.0.0.0 IS1!_NEXT_HOP track 1
ip route 0.0.0.0 0.0.0.0 ISP2_NEXT_HOP 10 -- with higher metric
now if the track has been configured for example to pin ISP 1 every 30 seconds once the ping fail for exampel for 3 attempts the first default route will disapear forom therouteing table and the next one with higher metric will take effect using the other link next hop
also the bellow document has some examples and tricks might help you to configure it
