The interface becomes an MPLS tunnel — used exclusively for MPLS packets. You can
create different CCCs for different customers or for segregating different traffic streams
over different MPLS tunnels.
Using CCC, you can connect the following types of circuits:
•
Local interface with remote interface or VLAN
•
Local VLAN with remote interface or VLAN
NOTE:
To configure a VLAN circuit as a CCC, you must enable VLAN tagging
and specify a VLAN ID.
MPLS on EX Series switches does not support the following types of CCC configurations:
•
LDP-based MPLS
•
Routed VLAN interfaces (RVIs)
•
Q-in-Q tunneling
•
Aggregated Ethernet interfaces (LAGs) on CCCs
•
CCCs with a beginning and ending on the same switch
IP over MPLS For Customer-Edge Interfaces
You can configure the customer-edge interfaces of the PE switches for IP over MPLS
using a Layer 3 interface and a static route from the ingress PE switch to the egress PE
switch. See “Configuring MPLS on Provider Edge Switches Using IP Over MPLS (CLI
Procedure)” on page 3401 for additional information.
Provider Switch
You must configure one or more provider switches as transit switches within the network
to support the forwarding of MPLS packets. You can add provider switches without
changing the configuration of the PE switches.
A provider switch does not analyze the packets. It refers to an MPLS label forwarding
table and swaps one label for another. The new label determines the next hop along the
MPLS tunnel. A provider switch cannot perform the push or pop operations.
Components Required for All Switches in the MPLS Network
You must configure the following components on both the provider edge and the provider
switches:
