    Hi All,

    I have a problem with routers configured with dialer watch in an eigrp
    environment. The watch group "watches" 2 routes and places a backup
    isdn call if either are missing. However i have noticed from time to
    time dialer watch dials because eigrp hellos have not been recieved
    even though the primary link is up. I put this down to temporary
    congestion and configured custom queueing which has eigrp in the
    system queue 0 by default. This has not fixed the problem and i was
    wondering if anyone else has seen this or has a fix for it. The remote
    end is a 1601 router connecting via frame-relay to the core of the
    WAN.

    Any suggestions appreciated.

  2. Hello,

    maybe you do have problems with your framerelay-links.
    Sometimes it could happen, that the eigrp-hellos are dropped in the
    framerelay network.
    If you have framerelay cir + burst this is common due to DE-bit tagging
    of your provider, where the eigrp-packets could also be tagged.
    If you have only cir bought from your provider maybe it is a mismatch in
    the tc time (tc = bc / cir). If you have the same settings as your
    provider and the problem still appears, I suggest to set your own tc
    lower than your provider's tc setting.

    Regards Alois
