Note that both devices agree the master router is 192.18.38.1 (on the Juniper Virtual

Chassis), and both use a virtual IP address of 192.18.38.254.

If a router or link fails, the backup router should take over as the master. In this example,

the Cisco Nexus 7010 is promoted to master statement by reducing the Juniper Virtual

Chassis’ priority to 10. Since the Cisco Nexus 7010 uses a priority of 250 by default, it

will take over as master once this Juniper Virtual Chassis configuration change is

committed:

admin@EX9208> configure

admin@EX9208# set interfaces xe-5/0/5 family inet address 192.18.38.1/24

vrrp-group 1 virtual-address 192.18.38.254 priority 10

admin@EX9208# commit

After this change, the Juniper device becomes the backup router, and the master router is

now 192.18.38.254 on the Cisco device:

Wi@Fi&passthrough&

Objective!

To verify the ability of a Juniper switch to forward Wi-Fi management traffic between a

Cisco Wi-Fi controller and Cisco Wi-Fi access points.

Background!

Many enterprises provision wireless LAN access using one or more centrally managed

controllers that monitor and manage RF and data networking parameters in real time. In

this model, Wi-Fi access points (APs) distributed throughout the enterprise depend on the

controllers for their configurations. Thus, reliable connectivity between controllers and

access points is essential.
