		Chapter 1. Managing IPv6 Concepts

Nodes With Multiple Network Interfaces

If a node contains more than one network interface, you must create additional /etc/hostname.interface files for the additional network interfaces. You must create these files with a text editor (or using the touch command); the Solaris installation program does not create them for you.

IPv4 Behavior

For example, consider the machine timbuktu shown in Hosts in a Sample Network. It has two network interfaces and functions as a router. The primary network interface le0 is connected to network 192.9.200. Its IP address is 192.9.200.70 and its host name is timbuktu. The Solaris installation program creates the file /etc/hostname.le0 for the primary network interface and enters the host name timbuktu in the file.

The second network interface is le1; it is connected to network 192.9.201. Although this interface is physically installed on machine timbuktu, it must have a separate IP address. Therefore, you have to manually create the /etc/hostname.le1 file for this interface; the entry in the file is the router`s name, timbuktu-201.

IPv6 Behavior

If IPv6 is to be configured, all that is necessary is that the interfaces /etc/hostname6.le0 and /etc/hostname6.le1 exist. Each interface's addresses are configured automatically when the system is started.
