Good day - I'm experimenting changing a network to segment routing from LDP. I'm struggling with an issue where the ABRs are advertising interarea routes in area 0, but those routes are not associated with a MPLS label. I can successfully sr-mpls pin...

Hmmm. The system thinks its _both_ a ASBR and ABR. Don't know why it thinks its an ABR. Configuration follows.sh ospf vrf vrf10 VRF vrf10 active in Routing Process "ospf 1" with ID 0.0.0.10 Role: Primary Active NSR (Non-stop routing) is Enabled Su...

From [1]: These conditions set the forwarding address field to a non-zero address: OSPF is enabled on the ASBR's next hop interface AND ASBR's next hop interface is non-passive under OSPF AND ASBR's next hop interface is not point-to-point AND A...
