[j-nsp] ATM config

Fri Sep 4 03:13:38 EDT 2009

Hi Clue,

Your configurations for below mentioned requirement will be as follows in JUNOS.

Suppose you have installed atm pic in fpc 0 pic slot 0.

Configuration for Internet PVC

at-0/0/0 {
    mtu 9192;
    encapsulation atm-pvc;
    atm-options {
        pic-type atm2;
        promiscuous-mode {
            vpi 3;
        }
    }
    unit 101 {

          description ***Internet PVC***;
          encapsulation atm-snap;
          vci  3.101;

          family inet {
                  mtu 1500;
                  address x.x.x.x/30;

    }
}

Configuration for atm cross connect

at-0/0/0 {
    mtu 9192;
    encapsulation atm-pvc;
    atm-options {
        pic-type atm2;
        promiscuous-mode {
            vpi 3;
        }
    }
    unit 102 {
        description "1st pvc from Provider to be switched";
        encapsulation atm-ccc-cell-relay;
        vci 3.102;
    }
}

at-0/0/1 {
    mtu 9192;
    encapsulation atm-pvc;
    atm-options {
        pic-type atm2;
        promiscuous-mode {
            vpi 3; # suppose you are using same vp at cisco side too. you can change here if you want
        }
    }
    unit 102 {
        description "1st pvc to Cisco to be switched";
        encapsulation atm-ccc-cell-relay;
        vci 3.102;
    }
}

protocols {

  connections {
      interface-switch provider-to-cisco-1st-pvc {
         interface at-0/0/0.102;
         interface at-0/0/1.102;
    }
 }

}

Similarly you will switch the second pvc. 

Regards,

Farooq
