    Hi Zafer

    Some more datails for you:

    - the ATM NSAP address is useless since you do not appear to
    be using SVC's.
    - two PVC's are basically configured for nothing.
    - the VCI values should always be > 31 since 0-31 are reserved.

    But this does not explain why the ISIS does not work.

    The easiest way to get this to work would be to configure everything on
    a point-to-point subinterface...
    This way, you do not need 'protocol' statements.

    However, if you want to keep things this way, you need to
    configure 'protocol clns' under the PVC (and with the 'broadcast'
    keyword). The thing is that I don't know why we distinguish clns_is,
    clns_es and clns....a routing guy can know this better.. In any
    case, I recommend to test this: you can configure all 3 at the same
    time...

    Afedersin , yazdiktan sonra ingilizce yazdigimi farkettim.
    neyse idare et..

    sevgiler
