OS for EX Series Ethernet Switches, Release 10.3
This example includes an ingress or local PE switch, an egress or remote PE switch, and
one provider switch. It includes CCCs that tie the customer-edge interface of the local
PE switch (PE-1) to the customer-edge interface of the remote PE switch (PE-2). It also
describes how to configure the core interfaces of the PE switches and the provider switch
to support the transmission of the MPLS packets. In this example, the core interfaces
that connect the local PE switch and the provider switch are individual interfaces while
the core interfaces that connect the remote PE switch and the provider switch are
aggregated Ethernet interfaces.
NOTE:
Core interfaces cannot be tagged VLAN interfaces.
Core interfaces can be aggregated ethernet interfaces. This example
includes a LAG between the provider switch and the remote PE switch
because this type of configuration is another option you can implement.
For information on configuring LAGs, see "Configuring Aggregated Ethernet
Interfaces (CLI Procedure)" on page 1157.
Figure 85 on page 3366 shows the topology used in this example.

PE switch in this example.
