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

IPv6 VRRP and IPv6 VRRP-E v3 are supported on Brocade FESX, FSX 800, FSX 1600, and FCX IPv6

modules. IPv4 VRRP v3 is not supported on FCX devices.

NOTE

When you use the router vrrp command 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: Brocade

(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-VRRP-E-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-VRRP-E-router)#.

Configuring the Owner for IPv4 VRRP

To configure the VRRP Owner router for IPv4, enter the following commands on the router.

Brocade Router1(config)#router vrrp

Brocade Router1(config)#interface ethernet 1/6

Brocade Router1(config-if-1/6)#ip-address 192.53.5.1

Brocade Router1(config-if-1/6)#ip vrrp vrid 1

Brocade Router1(config-if-1/6-vrid-1)#owner

Brocade Router1(config-if-1/6-vrid-1)#ip-address 192.53.5.1

Brocade Router1(config-if-1/6-vrid-1)#activate
