across a service provider network.
This example describes how to configure L2PT:
Requirements on page 1127
Overview and Topology on page 1127
Configuration on page 1129
Verification on page 1130
This example uses the following hardware and software components:
Six J-EX Series switches, with three each at two customer sites, with one of the switches
at each site designated as the provider edge (PE) device
L2PT allows you to send Layer 2 PDUs across a service provider network and deliver them
to J-EX Series switches that are not part of the local broadcast domain.
Figure 32 on page 1128 shows a customer network that includes two sites that are connected
across a service provider network. Site 1 contains three switches connected in a Layer 2
network, with Switch A designated as a provider edge (PE) device in the service provider
network. Site 2 contains a Layer 2 network with a similar topology to that of Site 1, with
Switch D designated as a PE device.
