Replication between two sites is known as Intersite Replication. Since bandwidth two different sites is usually very limited, so intersite replication is used to manage and control replication traffic.

Intersite replication in Active Directory typically uses a compressed and encrypted format, such as Remote Differential Compression (RDC). This reduces the overall amount of data transferred between sites and helps minimize the impact on corporate WAN links. Additionally, administrators can schedule replication during off-peak hours to further optimize network bandwidth usage.
Only one domain controller will be used per site to replicate to another site(process called as intersite replication) it could be a bridge head server(selected DC to do replication from the site)or DC selected by ISTG protocol if enabled. there would be lot of DCs in intrasite replication within a site.

A Bridge head server is a domain controller that is used for intersite replication. This is the point of contact for a domain controller in another site. This passed replication traffic to a domain controller on another site. replication data is compressed and sent over IP or SMTP. To designate a preferred bridgehead server Open Active Directory Sites and Services -- In the console tree, right-click the domain controller that you want to make a preferred bridgehead server, and then click Properties -- On the General tab, click the intersite transport or transports for which this computer will be a preferred bridgehead server, and then click Add.
Active Directory replication uses compressed and encrypted traffic to reduce the impact on corporate WAN links. This helps in minimizing bandwidth usage and ensuring efficient communication between domain controllers.
ISTG is used for replication between sites ie intersite replication . it selects the bridge head server automatically which willl be authorised to replicate information to other bridge head server of other site. If the bridge head server goes down then due to ISTG a new server takes its place and administrator need not to intervene and there is no problem in replication.
if you have not selected any DC as bridgehead server then it automatically follows ISTG - InterSite Topology Generator,chooses its own DC to replicate and if this link is down makes another but if you define bridgehead server,in that case if the link fails the replication stops.
