OSPF - Routes not going from DB to route table

ITGK
Beginner
Beginner

Hi,

 

I have a problem getting the routes from the ospf database to the route table.

I have the following topology:

Router ---- Switch 3850 ---- Core 4500X

 

It's using VRF's and my first test is VRF07.

It uses multiple areas, Router in area 105, switch in area 0 and 105 and core in area 0.

 

On the router I see the routes in the OSPF database, but they don't get in to the routing table.

 

I've looked through the configuration, network types, timers etc. but everything seems to match.

 

Any help appriciated.

 

Configuration from devices is further down.

 

 

 

            OSPF Router with ID (192.168.203.105) (Process ID 7)

Hi

Try configuring the command: capability vrf-lite under the OSPF process. 

example: 

router ospf 1 vrf X

capability vrf-lite 

 

It could be generated by the DN bit. 

 

Hope it is useful

:-)
