Configuring parameters specific to VRRP

VRRP is configured at the interface level. This section describes how to implement a simple VRRP

configuration using all the default values.

NOTE

When you use the command router vrrp to enter the VRRP configuration mode, the command

prompt does not change and results in the general configuration command prompt as shown in the

following:

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:

Brocade(config-vrrpe-router)#

Configuring the VRRP version

You can specify the version for the VRRP instance. For example, use the following command to

configure the instance of VRRP to use VRRP v3.

Brocade(config-if-e100-1/3-vrid-13)# version v3

Syntax: [no] version v2 I v3

• VRRP v2 supports IPv4 environment

• VRRP v3 supports IPv4 and IPv6 environment

The default configuration is VRRP v2.

Backup preempt

mode

Prevents a Backup with a higher VRRP priority from

taking control of the VRID from another Backup that

has a lower priority but has already assumed control

of the VRID.

Enabled page 797

Slow Start Causes a specified amount of time to elapse between

the time the original Master router is restored and

when it takes over from the Backup router. For VRRP-E

only.

Disabled page 798

Scale Timer Allows you to increase timing sensitivity across all

configured or default VRRP-Extended timers. For

VRRP-E only.

Disabled page 799

Short-Path-

Forwarding

Enables VRRP-E Extension for Server Virtualization. If

enabled, the traffic that is destined to the clients will

travel through the short-path forwarding path (dashed

line) to reach the client (as shown in Figure 24.4 on

page 24-30). Any packets coming from the local

subnet of the virtual IP address will be routed to the

VRRP-E master router. For example, with VRRP-E

Extension for Server Virtualization enabled, the

traceroute output will show one extra hop that display

the Backup router's interface IP address
