This section describes some terms that are useful to know when you implement VRRP on your systems.backup router
A VRRP instance for a VRID that is active but not in the master state. Any number of backups can exist for a VRID. A backup router is ready to assume the role of the master router if the current master router fails.
A VRRP instance that performs the routing function for the virtual router at a given time. Only one master router is active at a time for a given VRID.
An IP address associated with a VRID from which other hosts can use to obtain network service. The VRIP is managed by the VRRP instances belonging to a VRID.
A predefined MAC address used by VRRP instances while executing in a media, such as Ethernet that uses MAC addressing. A virtual MAC addresses isolates the operation of the virtual router from the real router providing the routing function and is used instead of the real MAC address. A virtual MAC address is derived from the VRID.
A unique number used to identify a virtual router. VRIDs must be unique on a given network segment.
A pseudo network interface that is configured on top of a system's physical network adapter, also called a network interface card (NIC). A physical interface can have more than one VNIC. VNICs are essential components of network virtualization. For more information, see Part III, Network Virtualization and Resource Management, in Oracle Solaris Administration: Network Interfaces and Network Virtualization.
A program running on a router by using the VRRP implementation. A single VRRP instance can provide VRRP capability for more than one virtual router.
A single router image created by the operation of one or more routers that use VRRP.
