Virtual Router Redundancy Protocol (VRRP)
General Operation
6-6
Figure 6-1, below, illustrates a virtual router on VLAN 100 supported by Router
1 (R1) and Router 2 (R2).
Router 1 (R1)
VLAN VID: 100
IP: 10.10.100.1
Router 1 Configuration
VRID: 1
Status: Owner
Virtual IP Addr: 10.10.100.1
MAC Addr: 00-00-5E-00-01-01
Priority: 255
As long as R1 remains available, it
operates as the Master. If R1 fails,
then R2 takes over as Master.

Router 2 VR Operation
Configuration
1 All routers in the same VR have the same VRID.
Backup One Owner and one or more Backups are
allowed in a given VR.
10.10.100.1 The IP address configured for VLAN 100 in R1
(the Owner) is also configured as the Virtual IP
Address for VRRP in both R1 and R2.
For any VR in any VLAN, this is always defined
as 00-00-5E-00-01-< VRID >, and is not
configurable.
100 The router configured as Owner in any VR is
(Default) automatically assigned the highest priority
(255). Backup routers are assigned a default
priority of 100, which can be reconfigured.
Router 2 Configuration
VRID: 1
Status: Backup
Virtual IP Addr: 10.10.100.1
MAC Addr: 00-00-5E-00-01-01
Priority: 100
