Configuring VRRP

Figure 2 shows the same example network shown in Figure 1, but with a VRRP virtual router configured on

Router1 and Router2.

Figure 2

Router1 and Router2 are configured as a VRRP virtual router to provide redundant network access for

Host1

The dashed box in Figure 2 represents a VRRP virtual router. When you configure a virtual router, one of the

configuration parameters is the virtual router ID (VRID), which can be a number from 1 – 255. In this example, the

VRID is 1. The VRID must be unique within the LAN. VRIDs do not cross LAN boundaries. Thus, there is no

restriction against reusing a VRID with a different address mapping on different LANs.

NOTE: You can provide more redundancy by also configuring a second VRID with Router2 as the owner and

Router1 as the Backup. This type of configuration is sometimes called Multigroup VRRP.

Virtual Router ID (VRID)

A VRID consists of one Master router and one or more Backup routers. The Master router is the router that owns

the IP address(es) you associate with the VRID. For this reason, the Master router is sometimes called the

"owner". Configure the VRID on the router that owns the default gateway interface. The other router in the VRID

does not own the IP address(es) associated with VRID but provides the backup path if the Master router becomes

unavailable.
