DNS Configuration

DNS configuration includes procedures to the network-interface, realm-config, and session-agent elements.

To make DNS operational, configure addressing that is version compatible to the network-interface address on the network interface itself.

1. Access the network-interface configuration element.

   ORACLE# configure terminal
   ORACLE(configure)# system
   ORACLE(system)# network-interface
   ORACLE(network-interface)

2. dns-ip-primary—Set the first DNS server with which the interface conducts query procedures.
3. dns-ip-backup1—Set the second DNS server with which the interface conducts query procedures should the first server fail.
4. dns-ip-backup2—Set the third DNS server with which the interface conducts query procedures should the second server fail.

The system performs DNS query procedures with these servers every time processing encounters an FQDN for which the system needs resolution.

Review the ensuing sections and configure DNS components to refine DNS operation to your environment, including interface, realm, session agent, and ENUM operation refinement.
