:-)

Only the router with the highest router ID is supposed to forward to
area 0.0.0.0 the type 5 LSAs that are translated from the type 7 LSAs
originated by R3.

Do you think this will affect what you see in area 0.0.0.0?

What does 'show ip ospf database nssa-external <LSA ID>' and 'show ip
ospf database external <LSA ID>' on the ABR with highest router ID
tell you?

The propagate-bit in the LSA needs too be set in order for the type 7
to type 5 translation to occur. This will show up in the output from
'show ip ospf database nssa-external' as 'Type 7/5 translation'.
