Basic VRRP parameter configuration
To implement a simple VRRP configuration using all the default values, enter the commands shown in
the following sections.
Configuration rules for VRRP
• The interfaces of all routers in a VRID must be in the same IP subnet.
• The IP addresses associated with the VRID must already be configured on the router that will be the
Owner.
• An IP address associated with the VRID must be on only one router.
• The Hello interval must be set to the same value on the Owner and Backup routers for the VRID.
• The dead interval must be set to the same value on the Owner and Backup routers for the VRID.
• The track priority on a router must be lower than the router VRRP priority. Also, the track priority on
the Owner must be higher than the track priority on the Backup routers.
NOTE
When you use the router vrrp or the ipv6 router vrrp command to enter the VRRP configuration
mode, the command prompt does not change and results in the following general configuration
command prompt: (config)# . This differs from entering the VRRP extended mode, where entering
the router vrrp-extended command results in a command prompt such as the following: (config-
vrrpe-router)#. For IPv6 VRRP extended mode, when entering the ipv6 router vrrp-extended
command, this results in a command prompt such as the following: (config-ipv6-vrrpe-
router)#.
Configuring the Owner for IPv4 VRRP
To configure the VRRP Owner router for IPv4, enter the following commands on the router.
device Router1(config)#router vrrp
device Router1(config)#interface ethernet 1/6
device Router1(config-if-1/6)#ip-address 192.53.5.1
device Router1(config-if-1/6)#ip vrrp vrid 1
device Router1(config-if-1/6-vrid-1)#owner
device Router1(config-if-1/6-vrid-1)#version v3|v2
device Router1(config-if-1/6-vrid-1)#ip-address 192.53.5.1
device Router1(config-if-1/6-vrid-1)#activate
Syntax: [no] router vrrp
Syntax: [no] ip-address ip-addressp-address
Syntax: [no] ip vrrp vrid num
Syntax: [no] owner [ track-priority value ]
Syntax: [no] version num
Syntax: [no] activate
The ip-address variable specifies the IPv4 address of the Owner router.
The IP address assigned to the Owner must be an IP address configured on an interface that belongs
to the virtual router.
The num variable specifies the virtual router ID. Valid range is between 1 through 255.
