Virtual routing instances allow each EX Series switch to have multiple routing tables on
a device. With virtual routing instances, you can segment your network to isolate traffic
without setting up additional devices.
This example describes how to create virtual routing instances:
Requirements on page 1354
Overview and Topology on page 1355
Configuration on page 1355
Verification on page 1356
This example uses the following hardware and software components:
One EX Series switch
Junos OS Release 9.2 or later for EX Series switches
Before you create the virtual routing instances, make sure you have:
1 (Active = 0)
1 (Active = 0)
