Example:Configuring MX Series Router ATMEthernet Interworking
Considerthe router topology shown in Figure 13 on page79. The MX Series router is
configuredas the Provider Edge 2 (PE2) routerin the figure to support the ATM Ethernet
IWF.

Therelevant router interfacesare:
OnCE1, the CE1–PE1 interface is at-2/0/0 with IP address30.1.1.1/24
OnPE1:
ThePE1–CE1 interface is at-2/0/1 with no IP address required
ThePE1–PE2 interface is ge-5/0/0 with IP address20.1.1.1/24
OnPE2:
ThePE2–CE2 interface is ge-0/2/0 with no IP addressrequired
ThePE2–PE1 interface is ge-0/2/8 with IP address20.1.1.10/24
CE2interface is ge-0/0/0 with IP address30.1.1.10/24
NOTE: Theseare not completerouter configurations.
