[j-nsp] ATM2 pic connected to another M7i cannot get ISIS adjatency ; (

[Xavier Beaudouin]

Hi there,

I have 2 M7i with pic :
  PIC 3          REV 08   750-005724   CN5430            2x OC-3 ATM-II IQ, MM

Since I don't use ATM, I wanted to use this as interrouter connection using :

jun-m7i-1 at-0/3/0  <-> jun-m7i-2 at-0/3/0
jun-m7i-1 at-0/3/1  <-> jun-m7i-2 at-0/3/1

I finaly found a way to make the communication (ipv4) between the routers, but it doesn't seems to work with ISIS.

Here is jun-m7i-1 base configuration :

interfaces {

    at-0/3/0 {
        description "To jun-m7i-2_at-0/3/0";
        mtu 9192;
        clocking internal;
        encapsulation atm-pvc;
        atm-options {
            pic-type atm2;
            vpi 1;
        }
        unit 0 {
            encapsulation atm-snap;
            vci 1.100;
            oam-period 3;
            oam-liveness {
                up-count 3;
                down-count 3;
            }
            family inet {
                address xx.xx.xx.125/30;
            }
            family iso;
        }
    }
    at-0/3/1 {
        description "To jun-m7i-2_at-0/3/1";
        mtu 9192;
        clocking internal;
        encapsulation atm-pvc;
        atm-options {
            pic-type atm2;
            vpi 1;
        }
        unit 0 {
            vci 1.100;
            family inet {
                address xx.xx.xx.121/30;
            }
            family iso;
        }
    }

    lo0 {
        description Loopback;
        unit 0 {
            family inet {
                no-redirects;
                primary;
                address xx.xx.xx.1/32 {
                    primary;
                    preferred;
                }
            }
            family iso {
                address 49.0001.0xxx.xxxx.xxx1.00;
            }
        }
    }
}

On jun-m7i-2 :

interfaces {
    at-0/3/0 {
        description "To jun-m7i-1_at-0/3/0";
        mtu 9192;
        clocking internal;
        encapsulation atm-pvc;
        atm-options {
            pic-type atm2;
            vpi 1;
        }
        unit 0 {
            encapsulation atm-snap;
            vci 1.100;
            oam-period 3;
            oam-liveness {
                up-count 3;
                down-count 3;
            }
            family inet {
                address xx.xx.xx.126/30;
            }
            family iso;
        }
    }
    at-0/3/1 {
        description "To jun-m7i-1_at-0/3/1";
        mtu 9192;
        clocking internal;
        encapsulation atm-pvc;
        atm-options {
            pic-type atm2;
            vpi 1;
        }
        unit 0 {
            encapsulation atm-snap;
            vci 1.100;
            family inet {
                address xx.xx.xx.122/30;
            }
            family iso;
        }
    }
    lo0 {
        description Loopback;
        unit 0 {
            family inet {
                no-redirects;
                primary;
                address xx.xx.xx.xx/32 {
                    primary;
                    preferred;
                }
            }
            family iso {
                address 49.0001.0xxx.xxxx.xxx2.00;
            }
        }
    }
}
