First of all, thanks for at least giving it a go. I think there's a few
points of confusion though. Bridge all site links is enabled by default
and should be enabled, otherwise you would need to manually specify
site-link bridges (which is not recommended by Microsoft and not
implemented in the KCC currently).
Is the new KCC running on all the DCs you mention?
Denis Cardon had a go briefly and found that he needed to specify a
bridgehead before any connections were made. We weren't able to confirm,
but it's possible that specifying a bridgehead may help.
So now to your topology, you mentioned that those connections should not
have been removed? Do you have any specific reasons why? If everything
was functioning, there should be even more connections missing than you
see right now. The general idea of using the topology is to make sure
that a site contains only 1 in and 1 out link across all the DCs within
that site (as well as additional links within a site). The fact that
everything was connected before was the cause of bandwidth issues.
The following would be similar to what I would actually expect:
NTDS Settings SDC2
NTDS Settings SDC1
NTDS Settings PDC2
NTDS Settings PDC1
NTDS Settings DDC2
NTDS Settings DDC1
Probably one of the most annoying things about replication and testing
replication is that it doesn't necessarily trigger immediately. It's
definitely not something which is straightforward to test, or implement.
