Example: Configuring MX Series Router ATM Ethernet Interworking
Consider the router topology shown in Figure 13 on page 79. The MX Series router is
configured as the Router PE2 (the provider edge 2 router) in the figure to support the
ATM Ethernet IWF.

The relevant router interfaces are as follows:
•
On Router CE1, the CE1–PE1 interface is at-2/0/0 with IP address 30.1.1.1/24.
•
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:
•
The PE2–CE2 interface is ge-0/2/0 with no IP address required.
•
The PE2–PE1 interface is ge-0/2/8 with IP address 20.1.1.10/24.
•
On Router CE2 interface is ge-0/0/0 with IP address 30.1.1.10/24.
NOTE: The example configurations in this section are not complete
configurations.
