2.2.1 Configuring multiple virtual interfaces

Multiple virtual interfaces can be defined in a single system. With this capability, the number of available transfer routes within a single system can be increased, which will be useful for a system requiring multiple networks, such as application gateway. With the multiple virtual interfaces, high network reliability can be ensured.

• The virtual IP address of different subnet must be assigned to the multiple virtual interfaces.

Figure 2.12 below shows an example of defining 2 virtual interfaces. A virtual IP address of different subnet must be assigned in sha0 and sha1.
