Here is the diagram and config:
A---10.1.1.0/30-- B --10.1.1.4/30 -- C
|___ area 0_______|_____area 1_______|
The problem is on C. The route in question 1.1.1.1 shows up in RtrB.
Thanks.

Subject: OSPF route missing
Hi all,
I have a strange problem: route 1.1.1.1 is present in "show ip ospf
database" output as a LSA type5, but it does not show up in the routing
table. Any ideas?
Thanks
