2.2.3.2 Using NIC switching mode

Within several virtual interfaces of NIC switching mode (logical IP takeover), if all the name of the physical interfaces and the value of the physical IP addresses are equivalent, then it is possible to share the physical interface. Sharing a portion of physical interface is not allowed. Nevertheless, sharing is not possible for NIC switching mode (physical IP takeover). In addition, sharing physical interface with the virtual interface is not possible for Fast switching mode.

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

Figure 2.15 shows an example of three virtual interfaces sha0, sha1 and sha2 (all in NIC switching mode) sharing two physical interfaces eth1, and eth2.
