    Hi,


    we use Cisco catalyst 4006 to provide access service to our customers.
    this works fine in past months. there show long delay between computer
    and Fastethernet interface of 4006.


    Cisco 4006 --------------------------remote Router -- remote network
    ^ Fiber ^
    | |
    Fa3/4( 10.10.0.21/30) Fa 10.10.0.22/30

    We set up catalyst 4006 as follows:

    each Fastether interface is configured with a subnet like 10.10.0.21/30
    ..remote network is connected to this interface by setting up a
    Fastethernet interface with ip address 10.10.0.22/30.



    when 'ping' from 10.10.0.21 to remote router interface it show average delay
    4ms
    ,but if we 'ping' from remote router to 10.10.0.21 there is delay about
    18ms every 20~30
    packets. We test this by connecting a computer directly to fastethernet
    interface, it shows
    the same results(during this test, we set up both computer NIC and Fa3/4 to
    10Mbps duplex).

    Why? how could we solve this problem ?

    thanks in advance.

    Perhaps you have multiple routes that are possible, and the alternate
    route is being chosen from time to time ?
