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 1577
Overview and Topology on page 1577
Configuration on page 1578
Verification on page 1579
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:
Configured the necessary VLANs. See "Configuring VLANs for EX Series Switches (CLI
Procedure)" on page 1600 or "Configuring VLANs for EX Series Switches (J-Web
Procedure)" on page 1597.
In a large office, you may need multiple VLANs to properly manage your traffic. This
configuration example shows a simple topology to illustrate how to connect a single EX
