R1 takes backup link to reach R2 rather than MPLS route. On R1 there is mutual redistribution of OSPF with BGP.
Diagram on the setup is attached. Any clue
testing on a C6500:
red ospf 200 metric ?
<0-16777214> OSPF default metric
red ospf 200 metric 40000
% Only classful networks will be redistributed
so we need to use the subnets keyword
we set a metric in addition to using metric type O E2 (default) the idea is to make external routes coming from eBGP sessions preferred.
this is just an additional security measure if setting metric-type to 1 in redistributing BGP into main OSPF process you should be fine
red ospf 200 ?
match Redistribution of OSPF routes
metric Metric for redistributed routes
metric-type OSPF/IS-IS exterior metric type for redistributed routes
route-map Route map reference
subnets Consider subnets for redistribution into OSPF
tag Set tag for routes redistributed into OSPF
vrf VPN Routing/Forwarding Instance
the exact syntax should be
red bgp ASN metric-type 1 subnets
into main OSPF process (OSPF PID 10)
Hope to help
