Replicate DHCP Failover Using the DHCP Console
Applies To: Windows Server 2012 R2, Windows Server 2012
Use the following procedures to replicate DHCP settings using the DHCP console. When you have completed the procedures in this topic, return to the parent checklist: Checklist: Deploy DHCP Failover.
Replication is the process of copying settings from one or more failover-enabled DHCP scopes to on a DHCP server to the server’s failover partner.
Important
Replication can be initiated from either DHCP server in a failover relationship. Settings on the failover partner server will be overwritten with the settings that are configured on the server where replication is initiated. Therefore, it is important to always ensure replication is initiated on the server that is configured with the settings you wish to use.
This topic provides steps to replicate scope settings using the DHCP console. For steps to replicate scope settings using the command line, see Replicate DHCP Failover Using the Command Line.
Three types of replication are available:
Server replication: This type of replication copies the configuration of all failover-enabled scopes on the local server to its failover partner servers.
Relationship replication: This type of replication copies the configuration of all DHCP scopes that are part of a selected failover relationship to the failover partner server.
Scope replication: This type of replication copies the configuration of a selected DHCP scope to the failover partner server.
Choose one of the following procedures based on the type of replication you wish to perform:
Replicate failover settings at the server level using the DHCP console
Replicate failover settings at the relationship level using the DHCP console
Replicate failover settings at the scope level using the DHCP console
Replicate failover settings at the server level using the DHCP console
Membership in the Administrators group, or equivalent, is the minimum required to complete these procedures. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (https://go.microsoft.com/fwlink/?LinkId=83477).
To replicate failover settings at the server level using the DHCP console
On a DHCP server, open Server Manager, click Tools and then click DHCP.
In the DHCP console, right-click IPv4, and then click Replicate Failover Scopes.
Click OK in the alert that appears.
In the Failover Scope Configuration Replication dialog box, verify that replication was successful, and then click Close.
Replicate failover settings at the relationship level using the DHCP console
Membership in the Administrators group, or equivalent, is the minimum required to complete these procedures. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (https://go.microsoft.com/fwlink/?LinkId=83477).
To replicate failover settings at the relationship level using the DHCP console
On a DHCP server, open Server Manager, click Tools and then click DHCP.
In the DHCP console, right-click any failover-enabled scope, and then click Replicate Relationship.
Click OK in the alert that appears.
In the Failover Scope Configuration Replication dialog box, verify that replication was successful, and then click Close.
Replicate failover settings at the scope level using the DHCP console
Membership in the Administrators group, or equivalent, is the minimum required to complete these procedures. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (https://go.microsoft.com/fwlink/?LinkId=83477).
To replicate failover settings at the scope level using the DHCP console
On a DHCP server, open Server Manager, click Tools and then click DHCP.
In the DHCP console, right-click any failover-enabled scope, and then click Replicate Scope.
In the Failover Scope Configuration Replication dialog box, verify that replication was successful, and then click Close.
