Example: Configuring ATM-to-Ethernet Interworking

The following example shows the configuration of the ATM and Ethernet interfaces for an ATM-to-Ethernet interworking cross connect. In the example ATM DSLAM traffic is terminated on an ATM2 interface. The ATM traffic is forwarded using encapsulation type vlan-vci-ccc to a local Ethernet IQ2 interface. See the topology in Figure 14.

In this example, the ATM traffic comes from the DSLAM to the router on ATM interface at-4/0/0 and is forwarded out on Ethernet interface ge-2/2/1.

ge-2/2/1 {
vlan-vci-tagging;
encapsulation vlan-vci-ccc;


unit 0 {
encapsulation vlan-vci-ccc;
vlan-id 100;

}


}

}




unit 0 {

}
