Overview
24
Figure 113 shows the same example network shown in Figure 112, but with a VRRP virtual router
configured on Switch 1 and Switch 2.
FIGURE 113 Switch 1 and Switch 2 are configured as a VRRP virtual router for redundant network
access for Host1
The dashed box in Figure 113 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.
NOTE
You can provide more redundancy by also configuring a second VRID with Switch 2 as the Owner and
Switch 1 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.
