Configuring MPLS on Provider Edge Switches Using Circuit Cross-Connect (CLI
Procedure)
Copyright © 2010, Juniper Networks, Inc.
Junos MPLS for EX Series switches supports Layer 2 protocols and Layer 2 virtual private
networks (VPNs). 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
switch. You can configure the customer-edge interfaces on the PE switches of the MPLS
network as either circuit cross-connect (CCC) or using MPLS over IP. For information on
configuring MPLS over IP, see "Configuring MPLS on Provider Edge Switches Using IP
Over MPLS (CLI Procedure)" on page 3691. You can also use class of service (CoS) on
MPLS networks. For further information, see "Understanding Using CoS with MPLS
Networks on EX Series Switches" on page 3394.
This topic describes configuring PE switches using a circuit cross-connect (CCC). The
customer-edge interface can be either a simple interface or a tagged VLAN interface. In
both cases, you configure the logical unit of the customer-edge interface to belong to
and you must configure an association between that interface and two
family ccc
label-switched paths (LSPs)—one for transmitting MPLS packets to the remote PE and
the other for receiving MPLS packets from the remote PE.
The following guidelines apply to CCC configurations:
When an interface is configured to belong to
family.
You can send any kind of traffic over a CCC, including nonstandard bridge protocol
data units (BPDUs) generated by other vendors' equipment.
If you are configuring a CCC on a tagged VLAN interface, you must explicitly enable VLAN
tagging and specify a VLAN ID.
NOTE: The VLAN tag ID cannot be configured on logical interface unit
logical unit number must be
This procedure shows how to set up two CCCs:

To configure a PE switch, complete the following tasks. When you have completed
configuring one PE switch, perform the same tasks on the other PE switch:
