[harry]

Hmm. The database seems OK. 

See below for some <<<<< call outs.

<<<< Router LSA from router B, 10.2.255.7 (RID). The LSA reports the RID of
Router A (10.2.255.8), and router A's IP address , 10.2.255.93. Router A
should now know how to reach the router identified as "10.2.255.7" by using
the 10.2.255.92/30 subnet.

<<< The external route is advertised by Router B, RID 10.2.255.7. Even
though this RID may not be a route (normally is not when a manual RID is
set), a route to that router owning that RID should be known via router B's
router LSA. IOW, it seems like this should result in externals in the route
table, from what I have seen.

Besides a support case, and/or remove manual RIDs, I would also suggest some
tracing while you restart routing (assumes a test bed) on one of the
routers.


I would start by tracing with:

traceoptions {
    file ospf-trace;
    flag error detail;
    flag lsa-update detail;
}


HTHs.
