Example 2 – HA Pair for Internal DNS and DHCP
In this example, you set up an HA pair of Infoblox-550 appliances to provide internal DNS and DHCP services. The
HA pair answers internal queries for all hosts in its domain (corp100.com). It forwards internal queries for external
sites to ns1.corp100.com at 10.1.5.2 and ns2.corp100.com at 2.2.2.2. It also uses DHCP to provide dynamic and
fixed addresses.
The HA pair consists of two devices (nodes). The IP addresses of the VIP (virtual IP) address of the HA pair and the
HA and LAN1 ports on each node, are as follows:
The virtual router ID number for the HA pair is 150. (The ID number must be unique for this network segment.)
When you create the corp100.com zone on the HA pair, you import DNS data from the legacy server at 10.1.4.11.
