vrf ospf router and totaly stub

daniel-nilsson
Level 1
Level 1

Is there any particular reason that OSPF refuses to send default route from the ABR to the remote site? The command "area 123 stub no-summary" does not do the trick, the remote router will not receive the default route. Note that this works perfectly without VRF.

The command "show ip ospf"
Area 123

        Number of interfaces in this area is 2 (1 loopback)

        It is a stub area, no summary LSA in this area

         generates stub default route with cost 1 (this is missing)

Many thanks

Hello Daniel,

please post the relevant parts of configuration to get better help.

Is the default route locally generated on PE node or received as an MP BGP route from another VRF site?

If coming from other site, are you using the same OSPF process-ids on local PE and remote PE node?

What about the domain-id?

Several informations are coded in extended BGP communities and one of them is the OSPF process-id.

Hope to help

Giuseppe

I dont use MPLS, only VRF-lite and OSPF in this setup

The link between central and remote site is DMVPN.

2 tunnels, one global routing and one with VRF

The command "area 123 stub no-summary" should generate a default by the central ABR and it does so for the tunnel with global routing/without VRF, but the tunnel that is part of vrf doesnt seem to generate a default.

As a workaround i have made a new OSPF process for the vrf that only is part of DMVPN area, in that OSPF process i have made a "default-information orginate always" and then some redistribution between the 2 OSPF process in that VRF.

Thanks
