B.1.3 Configuring virtual interfaces with tagged VLAN

This section describes an example configuration procedure of the network shown in the diagram below.

[HOST-A]

1) Setting up the system

1-1) Define IP addresses and hostnames in /etc/hosts file.

192.168.10.1    hosta1   # HOST-A Virtual IP
192.168.20.1    hosta2   # HOST-A Virtual IP
192.168.30.10   hosta3   # HOST-A Physical IP (Tagged VLAN interface)
192.168.40.10   hosta4   # HOST-A Physical IP (Tagged VLAN interface)
192.168.50.10   hosta5   # HOST-A Physical IP (Tagged VLAN interface)
192.168.60.10   hosta6   # HOST-A Physical IP (Tagged VLAN interface)
192.168.10.2    hostb1   # HOST-B Virtual IP
192.168.30.20   hostb3   # HOST-B Physical IP
192.168.40.20   hostb4   # HOST-B Physical IP
192.168.20.2    hostc2   # HOST-C Virtual IP
192.168.50.20   hostc5   # HOST-C Physical IP
192.168.60.20   hostc6   # HOST-C Physical IP

1-2) Configure /etc/sysconfig/network-scripts/ifcfg-ethX (X is 0,1) file as follows.

In example (/etc/sysconfig/network-scripts/ifcfg-ethX) of setting the following, operating system is an example of RHEL4. Please refer to "3.2.2 Network configuration" for the setting examples other than RHEL4.
