Configuring MPLS on Provider Edge Switches Using IP Over MPLS (CLI Procedure)

You can add class-of-service (CoS) components to your MPLS networks on EX Series
switches to achieve end-to-end Differentiated Services to match your specific business
requirements. The configuration of CoS components on the provider switches is the same
regardless of whether the provider edge (PE) switches are using MPLS over CCC or IP
over MPLS.
This task shows how to configure a custom EXP classifier and custom EXP rewrite rule
on the provider switch.
Import the default EXP classifier classes to the custom EXP classifier that you are

creating:
[edit class-of-service]

Add the expedited-forwarding class to this custom EXP classifier, specifying a loss

[edit class-of-service]
user@switch# set rewrite-rules exp e1 forwarding-class expedited-forwarding

NOTE: You can also configure schedulers and shapers as needed. See
"Defining CoS Schedulers (CLI Procedure)" on page 3209.

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 or
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 switch.
You can configure the customer-edge interfaces on the PE switches of the MPLS network
as either circuit cross-connect (CCC) or using IP over MPLS.
The main differences between configuring IP over MPLS and configuring MPLS over CCC
are that for IP over MLPS you configure the customer-edge interfaces to belong to
