Time for some VRRP

One thing cool about VRRP, you don’t have to burn an IP address just for the

virtual. You can use an actual physical IP address of a router. If that

router goes off-line, then the other router will just assume the IP address.

R1 up first, and we will use the R1 Te0/1/0/0 IP address for the virtual.

First though, we need to remove HSRP and save the changes.

RP/0/RSP0/CPU0:R1(config)#no router hsrp

RP/0/RSP0/CPU0:R1(config)#commit

Ok, to configure VRRP the command is router vrrp

RP/0/RSP0/CPU0:R1(config)#router vrrp

Again, then you tell it what interface

RP/0/RSP0/CPU0:R1(config-vrrp)#interface tenGigE 0/1/0/0

Since VRRP likes IPV6, we need to use the address-family command

RP/0/RSP0/CPU0:R1(config-vrrp-if)#address-family ipv4

Then configure our VRRP ID

RP/0/RSP0/CPU0:R1(config-vrrp-address-family)#vrrp 1

Assign the IP, here I am using the same IP as our physical interface

RP/0/RSP0/CPU0:R1(config-vrrp-virtual-router)#address 150.1.12.1

RP/0/RSP0/CPU0:R1(config-vrrp-virtual-router)#text-authentication cisco

RP/0/RSP0/CPU0:R1(config-vrrp-virtual-router)#commit

RP/0/RSP0/CPU0:R2(config-vrrp-virtual-router)#

Now for R2, but this time we will decrease the priority so that R1 is the

active router

RP/0/RSP0/CPU0:R2(config)#no router hsrp

RP/0/RSP0/CPU0:R2(config)#commit

RP/0/RSP0/CPU0:R2(config)#router vrrp

RP/0/RSP0/CPU0:R2(config-vrrp)#interface tenGigE 0/1/0/0

RP/0/RSP0/CPU0:R2(config-vrrp-if)#address-family ipv4

RP/0/RSP0/CPU0:R2(config-vrrp-address-family)#vrrp 1

RP/0/RSP0/CPU0:R2(config-vrrp-virtual-router)#address 150.1.12.1

RP/0/RSP0/CPU0:R2(config-vrrp-virtual-router)#text-authentication cisco

RP/0/RSP0/CPU0:R2(config-vrrp-virtual-router)#priority 50

RP/0/RSP0/CPU0:R2(config-vrrp-virtual-router)#commit

RP/0/RSP0/CPU0:R2(config-vrrp-virtual-router)#

RP/0/RSP0/CPU0:R2#
