Site Links, and Connections are two different things. Site Links are not 
automatically created (except the Default First Site Link). You create these 
manually between sites.

Once you've created your site links, the ISTG (Inter Site Topology Generator) 
generates the connection objects between DCs.

Note the difference: Site Links are between sites. Connection objects are 
between DCs

When Bridge All Sites Links is enabled, then site links are considered 
transitive. E.g. consider the following scenario (and each site has a single 
DC):

Birmingham <- Site Link 1 -> London <- Site Link 2 -> New York

In this case, if site links are transitive, then connection objects will be 
generated between BirminghamDC <-> LondonDC and LondonDC <-> NYDC and also 
between BirminghamDC <-> NYDC. If you don't want replication to flow 
BirminghamDC <-> NYDC then you need to disable "bridge all site links"

Now, if you case, you have something pretty much the same as this:

You'd want to disable "bridge all site links" and create the necessary site 
link bridges manually.

Cheers
Ken

Ben/Ken,

Sorry for the hijack, but my question may answer Ben's as well.  Ken are you 
talking about preventing AD from automatically creating site links between all 
DC's in a network?  I am building a AD proposal for about 6 sites and if my 
design is right I am going to have 3 sites US side with a main site link from 
the Miami location to the London location.  From the London location it will 
goto the 2 offices on that side of the Atlantic.  This way I only have 
replication going from Miami to London across that one Link, the remote offices 
on each side replicate with Miami and London respectively.

If I need other connectors to other DC's for example; if Miami's DC fails I 
would need to manually create them from Site B and C to London.  Is my thinking 
correct here?  If so, then this may explain Ben's issue as well.  One of his 
sites may have it turned off.

I also see the only benefit in disabling all bridged site links is to control 
replication topology generation for the purpose of bandwidth control.  Is that 
correct?
I have also read that with SP1 and SP2, DFS site costing is no longer broken 
with the disabling of all Bridged site links, which means I have independent 
control of DFS Replication despite the Site Links...this I have to test in a 
lab since that is pretty much its sole purpose to provide reps in the area up 
to date documentation that they sync with their laptops and automated SW 
installation for the equipment through GP and scripting.  This level of AD 
stuff is still a bit to new for me to be sure of anything yet.

You don't mention if you created site links between all your sites. Also, do 
you have "Bridge all site links" enabled or disabled?

I have one ad structure with 16 sites geographically dispersed. When I goto add 
a new site (and its been this way) the automatic generated connectors will 
connect some but not all other sites. For example, I add Site10 and it will 
create connectors for sites 1,2,3,6,7,8.Not a huge deal because I can add it 
manually but im trying to look at why it does this. Normally I have a handful 
of sites so have never seen this.  There seems to be no specific case each tiem 
I add a site it will add some random number of ad connectors.
