2.2.3.1 Using Fast switching mode

One portion or entire physical interfaces can be shared by the virtual interfaces which institute Fast switching mode. Though, it is not possible to share the physical interface and virtual interface of NIC switching mode.

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

Figure 2.14 shows an example of three virtual interfaces, sha0, sha1, and sha2 (All in Fast switching mode) sharing three physical interfaces eth1, eth2, and eth3.
