Thanks for the response. That's how we have ospfd configured. However, the ospf cost on lo:0 is not added to the metric. Only the ospf cost of the peering router gets added to the metric. FWIW, our ospf area is nssa.
ospf router-id 10.248.6.4
network 10.248.6.0/29 area 188.8.131.52
network 192.168.20.12/32 area 184.108.40.206
network 192.168.20.13/32 area 220.127.116.11
area 18.104.22.168 nssa translate-never
