I have two BGP routers one connected via MPLS and the other one is connected via Private T1 Line. Both Routers have EBGP connections to MPLS and to the T1 and also have IBGP session between them. The Ethernet ports on both routers are connected to the LAN Routers via EIGRP. The BGP routers are receving Default Routes from the BGP Cloud and then advertised Default Routes to EIGRP via redistribution. We would like MPLS default routes as a primary path to internal EIGRP router and backup by default routes via other BGP router.
What would be the best way to configure this. Would change the metrics while redistributing default routes into EIGRP work such as:
on T1 BGP WAN Router:
redistributed static route-map CHANGE-METRIC
route-map CHANGE-METRIC permit 10
match ip address 99
set metric 412284672 100 255 1 1500
access-list permit 99 0.0.0.0 0.0.0.0
