Table 2-2 describes the different interfaces, IP address settings, and the
resolutions in a cluster.
Configuring a DNS Server
To configure a DNS server using GNS:
1 Configure GNS VIP address on DNS server—In the DNS, create a name
resolution entry for the GNS virtual IP address in the forward Lookup file.
For example:
gns-server IN A 192.0.2.2
where gns-server is the GNS virtual IP address given during grid installation.
The address that you provide must be routable and should be in public
range. For example, 192.0.2.2.
2 Configure the GNS sub-domain delegation—In the DNS, create an entry to
establish DNS Lookup that directs the DNS resolution of a GNS sub-
domain to the cluster. Add the following to the DNS Lookup file:
clusterdomain.example.com. NS gns-server.example.com .
where
clusterdomain.example.com is the GNS sub domain (provided during
grid installation) that you delegate and
gns-server.clustername.com resolves
to GNS virtual IP address.
