The optional priority 255 statement forces the Juniper switch’s virtual IP address to

become the master VRRP instance, assuming the Cisco Nexus 7010 device uses a lower

priority value. The legal range of VRRP priorities is 1 though 255, with 255 being

highest.

Cisco!commands!

1. Ensure the VRRP feature is installed. This step is not required with Cisco Catalyst

switches:

Nexus7010# configure terminal

Nexus7010(config)# feature vrrp

2. Define interface and VRRP virtual IP addresses on interface Ethernet3/10:

Nexus7010(config)# interface Ethernet3/10

Nexus7010(config-if)# description VRRP to EX9208 xe-5/0/5

Nexus7010(config-if)# no switchport

Nexus7010(config-if)# ip address 192.18.38.2/24

Nexus7010(config-if)# vrrp 1

Nexus7010(config-if-vrrp)# address 192.18.38.254

Nexus7010(config-if-vrrp)# no shutdown

Nexus7010(config-if-vrrp)# exit

Nexus7010(config-if)# no shutdown

Nexus7010(config-if)# end

Note the explicit “no shutdown” commands for both physical and virtual interfaces.

These commands are mandatory with Cisco Nexus 7000 switches, but are not required

with Cisco Catalyst switches.

Validation!

On Juniper devices, the show vrrp summary command will indicate the current

VRRP state on each system. In the following examples, the Juniper Virtual Chassis acts

as VRRP master and the Cisco Nexus 7010 acts as a backup.

On the Juniper Virtual Chassis:

admin@EX9208# run show vrrp summary

Interface State Group VR state VR Mode Type Address

xe-5/0/5.0 up 1 master Active lcl

192.18.38.1

vip

192.18.38.254

The equivalent command on Cisco devices is show vrrp summary:

1 2 ... 71 72 73 74 75 76 77 78 79 80 81 82 83
