FIGURE 33 Devices configured as VRRP virtual routers for redundant network access for Host 1
The blue rectangle in the figure represents a VRRP virtual router. When you configure a virtual router, one of the configuration parameters
is a group number (also known as a virtual router ID or VRID), which can be a number from 1 through 255. The virtual router is identified
with a group, and within the VRRP group, there is one physical device that forwards packets for the virtual router and this is called a
master VRRP device. The VRRP master device may be a Layer 3 switch or a router.
In VRRP, one of the physical IP addresses is configured as the IP address of the virtual router, the virtual IP address. The device on which
the virtual IP address is assigned becomes the VRRP owner, and this device responds to packets addressed to any of the IP addresses
in the virtual router group. The owner device becomes the master VRRP device by default and is assigned the highest priority. Backup
devices are configured as members of the virtual router group, and, if the master device goes offline, one of the backup devices assumes
the role of the master device.
NOTE
VRRP operation is independent of BGP4, OSPF, and RIP. Their operation is unaffected when VRRP is enabled on the same
interface as BGP4, OSPF, and RIP.
VRRP terminology
The following are key terms and definitions that you must understand before implementing VRRP in your network.
The following VRRP-related terms are in logical order, not alphabetic order:
