Example: Configuring ATM1 Interfaces

The following configuration is sufficient to get an ATM1 OC3 or OC12 interface up and running. By default, ATM interfaces use ATM PVC encapsulation.



[edit interfaces]
at-fpc/pic/port {


atm-options {
vpi vpi-identifier maximum-vcs maximum-vcs-value;
unit 0 {     # one unit per VC
vci vpi-identifier.vci-identifier;


family inet {


address local-address {
destination address;
}


}


}


unit 1 {# second VC
...
}
