Multi-interface DNS/DHCP Servers with dedicated management enabled can also be configured for xHA. With services and management split between the Service and Management interfaces, xHA with dedicated management requires the use of virtual IPv4 addresses for both the service interface and the management interface.
The following diagrams illustrate the creation of an xHA pair using DNS/DHCP Servers with dedicated management enabled.
Dedicated Management before xHA
xHA with Dedicated Management enabled
When creating xHA with dedicated management, you must add new IPv4 addresses for the Service interface (eth0) and the Management interface (eth2), as the original IPv4 addresses of DNS Server 1 becomes the virtual IP addresses of the xHA cluster.
Add new IPv4 addresses for the Service and Management interfaces for NODE-1:
- SRV eth0: x.x.0.52
- MGMT eth2: x.x.2.52
