Explanation

2.7.2 IP Address Requirements Before starting the installation, you must have at least two interfaces configured on each node: One for the private IP address and one for the public IP address. You can configure IP addresses with one of the following options: Dynamic IP address assignment using Oracle Grid Naming Service (GNS). If you select this option, then network administrators assign static IP address for the physical host name and dynamically allocated IPs for the Oracle Clusterware managed VIP addresses. In this case, IP addresses for the VIPs are assigned by a DHCP and resolved using a multicast domain name server configured as part of Oracle Clusterware within the cluster. If you plan to use GNS, then you must have the following: - A DHCP service running on the public network for the cluster - Enough addresses on the DHCP to provide 1 IP address for each node's virtual IP, and 3 IP addresses for the cluster used by the Single Client Access Name (SCAN) for the cluster Static IP address assignment. If you select this option, then network administrators assign a fixed IP address for each physical host name in the cluster and for IPs for the Oracle Clusterware managed VIPs. In addition, domain name server (DNS) based static name resolution is used for each node. Selecting this option requires that you request network administration updates when you modify the cluster. Oracle recommends that you use a static host name for all server node public hostnames. Public IP addresses and virtual IP addresses must be in the same subnet. Oracle only supports DHCP- assigned networks for the default network, not for any subsequent networks. Oracle® Grid Infrastructure Installation Guide 11g Release 2 (11.2) for Linux
