Configuring Load Balancing Using VRRP

You must first configure VRRP on the Gigabit Ethernet interfaces on the switch that connect to the IP
network before configuring VRRP for iSLB. For information on how to configure VRRP on a Gigabit
Ethernet interface, see the

Enabling VRRP for Load Balancing

To enable or disable VRRP for iSLB, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# islb vrrp 10 load-balance
Step 3
switch(config)# no islb vrrp 10 load-balance
Step 4
switch(config)# islb vrrp ipv6 20
load-balance
Step 5
switch(config)# no islb vrrp ipv6 20
load-balance

Verifying iSLB VRRP Load Balancing Configuration

To verify the iSLB VRRP load balancing configuration for IPv4, use the show vrrp vr command.
switch# show vrrp vr 1
---------------------------------------------------------------------------
To verify the iSLB VRRP load balancing configuration for IPv6, use the show vrrp ipv6 vr command.
switch# show vrrp ipv6 vr 1
--------------------------------------------------------------------

Displaying iSLB VRRP Information

Use the show islb vrrp summary vr command to display VRRP load balancing information.
switch# show islb vrrp summary vr 30
