AD Replication between child domains

Hello experts,

We have multiple child domain as per the site locations. So it is necessary to enable network reachability and create site link between each sites.
Any thoughts ?

Thanks for clarification

Is there any other needs to establish connectivity between any of the child domains ?
Do we need in anyway to replicated data between site child domains ?

Just a follow up

Sarang Tinguria

No there is no need to establish connectivity between child domain as far as AD is concerned.

Do we need in anyway to replicated data between site child domains ?

I did not understand this

I meant no replication is necessary at all between child domains of the sites?

Sarang Tinguria

Yes ..no need to replicate between child domains (Considering they are in different child domains) if they all are replicated with Parent domain

Can we creat bridgehead links to replicate via another site if connectivity with parent domain goes down?

Sarang Tinguria

Would not be beneficial if your replication with parent is broken then you need to make redundancy on that...replicating two child domains will not help

So If my network topology is hub and spoke then I should disable Auto Site Link Bridging because if not disabled then there may be replication problems.
Because currently I am getting replication errors between child domains

Sarang Tinguria

Please post repadmin /replsum from Hub site Domain controllers and repadmin /showreps and repadmin /replsum from affected child domain.

We disabled auto bridging links and created manual links as you suggested, so far didn’t see any new replication errors.
