94 ESR Series Routers Operation Manual
Enable VRRP:
R1(config-subif)# vrrp
R1(config-subif)# exit
Configure VRRP for 192.168.20.0/24 subnet in the created sub-interface.
Specify unique VRRP identifier:
R1(config-sub)#interface gi 1/0/6.60
R1(config-subif)# vrrp id 20
Specify virtual gateway IP address 192.168.20.1:
R1(config-subif)# vrrp ip 192.168.20.1
Specify VRRP group identifier:
R1(config-subif)# vrrp group 5
Enable VRRP:
R1(config-subif)# vrrp
R1(config-subif)# exit
Configuration changes will take effect when the configuration is applied:
R1# commit
Configuration has been successfully committed
R1# confirm
Configuration has been successfully confirmed
Configure R2 in the same manner.
In addition to tunnel creation, you should enable VRRP protocol (112) in the
firewall.
7.31 VRRP tracking configuration
VRRP tracking is a mechanism, which allows activating static routes, depending on VRRP state.
Objective: Virtual gateway 192.168.0.1/24 is organized for 192.168.0.0/24 subnet, using VRRP
protocol and routers R1 and R2. There is a link with singular subnet 192.168.1.0/30 between R1 and R2
routers. Subnet 10.0.1.0/24 is terminated only on R2 router. PC has IP address - 192.168.0.4/24 and
default gateway 192.168.1.1.
When router R1 is in vrrp backup state, traffic from PC will be transmitted without any additional
settings. When router R1 is in vrrp master state, additional route is necessary for subnet 10.0.1.0/24
through interface 192.168.1.2.
