Example: Configuring MX Series Router ATM Ethernet Interworking
Consider the router topology shown in
. The MX Series router is
configured as the Router PE2 (the provider edge 2 router) in the figure to support the
ATM Ethernet IWF.

.
•
On Router PE1:
•
The PE1–CE1 interface is
at-2/0/1
with no IP address required.
•
The PE1–PE2 interface is
ge-5/0/0
with IP address
20.1.1.1/24
.
•
On Router PE2:
•
