Guys,
I have a strange issue here on my Win2k3 Domain. I have my sites in a hub
and spoke topology. So Sites Links exist for A, B, C, D, E, etc. So we are
looking at A <--> B, A <--> C, A <--> D, A <--> E, etc. Now I have one site,
let say A <--> E, that seems to have established replication partnership
with all the other sites while the others only establish partnership with
the Hub Site A, as I expect them to be. Can anyone tell me what might be
going on here
Thanks

How's the site setup? What do the site link cost look like? Have you
enabled the "Bridge all site links" setting?

Cheers,

Sites are set up in hub and spoke topology.
A <--> B, A <--> C, A <--> D, A <--> E, etc
yes the default "Bridge all site links" is enabled.
Question? This site is now being brought into the AD structure so there is
no direct route to the hub site. It is currently connected to another spoke.
Could it be that these AD connection objects are there as a result of no
direct route and as a result they are just bridged connections?

I'm still not getting the full picture, I think. What site is being
brought into AD now? If there is no direct connect to the hub and BASL
is enabled, it'll figure a different way to replicate the data to its
partners as it assumes that routes can be chosen freely (that's what
BASL does)

Cheers,
Florian

Ok, then so i take it this is not something to worry about. It's not like an
administrator did this manually this is all the work of AD. Lets say the
site being brought online is site E which has no direct route to Site A
(Hub), but it has immediate connection with site D which in turn has a
direct route to site A. Did I make any sense there?

Yeah, that sounds reasonable. AD has some failover mechanisms that would
help it replicate its changes although direct partners get shut down. In
your scenario, it replication between E-D and D-A takes place. Now, in
case D goes down, AD will try to fail over to create another direct rep
connection between E-A - it just bridges the site links E-D/D-A to let
rep happen until D gets up again.

Cheers,
Florian

I agree this sounds reasonable, as well as default, especially if Bridging
is enabled.

If a network isn't fully routed, it is suggested by Microsoft to disable
"Bridge All Site Links".

Paul,
I've read the article and I understand. However, at this moment I would
prefer to leave site link bridging enabled. In addition this issue with the
site not being directly connected to the hub is temporary. So I can live
with the KCC creating all those connections for now.
Thanks Guys

Hi
When "Bridge all site links" is enable, that means that the existing Site
Links are fully connected to each other which means that COs can be created
using those same site links until 3 Hops.

I hope that the information above helps you.
Have a Nice day.
