MPLS route is still active in routing table even its corresponding OSPF route is not listed

Hi There,

I found MPLS route is still active in routing table even its corresponding OSPF route is not listed in routing table.

Ori Destination Gateway Mtr Flags VLAN Duration
mp 192.17.80.55/32 172.17.79.1 1 U--D---um-L-- CR1-DR1_902 0d:2h:57m:41s
mp 192.17.80.55/32 172.17.79.85 1 U--D---um-L-- CR1-DR1_782 0d:3h:37m:45s
#or 192.17.80.55/32 172.17.79.85 12 UG-D---um--f- CR1-DR1_782 0d:3h:37m:46s

Even increasing the OSPF cost of the link, its mpls route is still active in routing table and traffic is going via that link.

How can I increase the metric of mpls route ?

Best Regards,
Ronie

I don't understand the question. In your output, only the OSPF route is selected and installed in the FIB.

The problem is with your route priority being that they are both the same subnet mask. You can change the route priority with the "configure iproute priority" command.
