You can configure MPLS on EX Series switches to increase transport efficiency in your
network. MPLS services can be used to connect various sites to a backbone network and
to ensure better performance for low-latency applications such as VoIP and other
business-critical functions.
To implement MPLS on EX Series switches, you must configure two provider edge (PE)
switches—an ingress PE switch and an egress PE switch— and at least one provider
(transit) switch. You can configure the customer-edge interfaces on the PE switches of
the MPLS network as either circuit cross-connect (CCC) or IP (
This example shows how to configure an MPLS tunnel using a CCC. For information on
configuring MPLS with an IP interface, see "Configuring MPLS on Provider Edge Switches
Using IP Over MPLS (CLI Procedure)" on page 3401.

This example uses the following hardware and software components:
Junos OS Release 10.1 or later for EX Series switches
Three EX Series switches
Before you begin configuring MPLS, ensure that you have configured the routing protocol
(OSPF or IS-IS) on core interface and the loopback interface on all the switches. This
example includes the configuration of OSPF on the switches.
