VRF to default RT recursive lookup

[mnaiem]

Hi,

I have been testing TNSR and I see an issue with routing to next hop in this scenario.
TNSR peers with another router in BGP on loopback interface and this peering in default routing table.
On TNSR, I configured multiple VRFs where I'm importing routes from default table into VRFs tables 'import vrf default'.
Routes didn't show up in VRF table unless one of two actions to be taken:
1- Peer with upstream router on the directly connected link not loopback.
2- Configure a route-map with 'import vrf route-map' where I set the next hop for all imported routes to connected interface instead of loopback.

My understanding here if it could understand to resolve next-hop from default table, it should be able to recursively lookup how to reach this loopback from default table as well.

Is there a knob to enable this or it's a default behavior can not be overwritten?

Thanks
