VRRP Configuration¶

With the interfaces and routing in place, the next step is to add VRRP addresses to the interfaces on each node.

Primary Node¶

First, add the VRRP addresses to the primary node, R1:

r1 tnsr(config)# interface WAN
r1 tnsr(config-interface)# ip vrrp-virtual-router 228
r1 tnsr(config-vrrp4)# preempt true
r1 tnsr(config-vrrp4)# accept-mode true
r1 tnsr(config-vrrp4)# v3-advertisement-interval 100
r1 tnsr(config-vrrp4)# priority 254
r1 tnsr(config-vrrp4)# track-interface LAN priority-decrement 240
r1 tnsr(config-vrrp4)# virtual-address 203.0.113.228
r1 tnsr(config-vrrp4)# exit
r1 tnsr(config-interface)# exit
r1 tnsr(config)# interface LAN
r1 tnsr(config-interface)# ip vrrp-virtual-router 28
r1 tnsr(config-vrrp4)# preempt true
r1 tnsr(config-vrrp4)# accept-mode true
r1 tnsr(config-vrrp4)# v3-advertisement-interval 100
r1 tnsr(config-vrrp4)# priority 254
r1 tnsr(config-vrrp4)# track-interface WAN priority-decrement 240
r1 tnsr(config-vrrp4)# virtual-address 10.28.0.1
r1 tnsr(config-vrrp4)# exit
r1 tnsr(config-interface)# exit
r1 tnsr(config)#

Secondary Node¶

Next, add the VRRP addresses to the secondary node, R2:

r2 tnsr(config)# interface WAN
r2 tnsr(config-interface)# ip vrrp-virtual-router 228
r2 tnsr(config-vrrp4)# preempt true
r2 tnsr(config-vrrp4)# accept-mode true
r2 tnsr(config-vrrp4)# v3-advertisement-interval 100
r2 tnsr(config-vrrp4)# priority 100
r2 tnsr(config-vrrp4)# track-interface LAN priority-decrement 90
r2 tnsr(config-vrrp4)# virtual-address 203.0.113.228
r2 tnsr(config-vrrp4)# exit
r2 tnsr(config-interface)# exit
r2 tnsr(config)# interface LAN
r2 tnsr(config-interface)# ip vrrp-virtual-router 28
r2 tnsr(config-vrrp4)# preempt true
r2 tnsr(config-vrrp4)# accept-mode true
r2 tnsr(config-vrrp4)# v3-advertisement-interval 100
r2 tnsr(config-vrrp4)# priority 100
r2 tnsr(config-vrrp4)# track-interface WAN priority-decrement 90
r2 tnsr(config-vrrp4)# virtual-address 10.28.0.1
r2 tnsr(config-vrrp4)# exit
r2 tnsr(config-interface)# exit
r2 tnsr(config)#
