Before creating the pair, ensure the service point has been enabled successfully on both DNS/DHCP servers. For more information, refer to Viewing the DNS Edge service point health and configuration.
- On the server assigned as the Active node, add the service point IPv4 address as an additional IPv4 address on the Service interface (eth0).
Configure both DNS/DHCP Servers with the same DNS Edge URL, site ID, and
service point IPv4 address.
Note: If you do not configure both DNS/DHCP Servers with the same DNS Edge URL, site ID, and service point IPv4 address, the HA pair creation will break.Note: Proxy Settings
If the proxy settings are configured, the proxy host, port, and user settings must be identical.
- Wait for the service point to be enabled successfully on both servers.
Create the pair.
Once the xHA pair is successfully created, you can reconfigure the client devices with the service point IPv4 address as the client device's nameserver. In this configuration, the service point on the Active node can process the incoming client traffic, and all operational DNS traffic and any other non-DNS traffic will continue to be processed by the Active DNS/DHCP server.
