Doug, I have looked at the topology and your explanation.
I am looking at MelonHQ and MelonBranch to start with. With no sham-link in place when you apply show ip ospf database what LSAs do you see? Do you see any LSA type 3? I am imagining you should see them in the database but in the route table you should only see O routes provided backdoor link and customer site used Area 0 altogether. Once you break the backdoor link, the type 3 LSA from the database should appear in the route table as IA. Is this what you see? Sorry if you have answered such questions before. Regards, Samir.
