Hi @Garry Cooper 

You need to configure the "default-information originate" command under the VRF settings in OSPF config mode:

router ospf 11
  default-information originate always
  vrf PUBLIC
    default-information originate always
    bfd
    router-id 10.248.65.1
    log-adjacency-changes detail
    auto-cost reference-bandwidth 100000 Mbps
    passive-interface default

Stay safe,

Sergiu.

Thanks for the reply....

But its in my config..

Here is same as above.

router ospf 11
default-information originate always
vrf PUBLIC
bfd
router-id 10.248.65.1
log-adjacency-changes detail
auto-cost reference-bandwidth 100000 Mbps
passive-interface default

Yes, but it is configured in default vrf. You have to move it under "vrf PUBLIC".

Change your config from this:

router ospf 11
  default-information originate always
  vrf PUBLIC
    bfd
    router-id 10.248.65.1
    log-adjacency-changes detail
    auto-cost reference-bandwidth 100000 Mbps
    passive-interface default

to this:

router ospf 11
  vrf PUBLIC
    default-information originate always
    bfd
    router-id 10.248.65.1
    log-adjacency-changes detail
    auto-cost reference-bandwidth 100000 Mbps
    passive-interface default

Cheers,
