Ops it shows you emailed 5 days ago but I got this one today. Since the domain Id is the same on both PEs sham link shall not matter. I will have to replicate this. Logically CE shall see LSA 3s if domain id are the same on both PEs.

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?
