Router stops passing traffic

    I've got a 1720 router I'm using on our company's frame relay network
    that stops passing traffic 3 or 4 times a week. Here's typically what
    happens:

    1. Users on the remote end loose connectivity.
    2. From the host router, I can ping the remote router.
    3. From the host router, I cannot ping any network device behind the
    remote router.
    4. I telnet to the remote router and reload it.
    5. After it reboots, all is well and traffic can pass in both
    directions.

    I have taken a look at TAC document 15105, "Troubleshooting Router
    Hangs". I saw in that document a section about "wedged" interfaces
    and followed the steps there to troubleshoot that possibility, but it
    doesn't appear to be the problem.

    Below I've copied the output from "show tech-support" from the most
    recent hang on the remote frame router. Any suggestions for solving
    this issue are much appreciated.

    Do you mean the frame switch? I'll have to check with Sprint, our
    telco, as they manage the frame switches.

    The odd thing is is that I have 4 other 1720 routers with the same
    software release--12.1(8c)--and I've not had this issue with any of
    those routers.

    Thanks,
    Tim

    they can't connect to corporate? what about each other, can one pc ping
    another pc that is locally at that site? can they ping the local router's
    ethernet address (their default gateway ip)? what application are they using
    (in general terms, http? etc...)? can they run a ping or traceroute from
    their desktops to the 'host/corporate' router?

    just the wan interface or can you ping the router's ethernet interface as
    well?

    when you log onto the remote router can you ping back to the 'host' router
    when using an extended ping and sourcing from the remote router's ethernet
    interface?

    before you reload it, can you ping any of the workstations that are on the
    same local segment as the router's ethernet address?

    To corporate. Everything on the local lan segment at the remote site
    functions. The only thing I'm not sure about is whether they can ping
    the router's ethernet interface from a PC on the local lan. I'll
    check that the next time this problem arises.

    Both. I can ping both the ip address for the ethernet interface and
    the ip for the wan interface.

    Not sure what you mean by "extended" ping, but I can ping the host
    router's ethernet interface from the remote router.

    No. From the remote router, I cannot ping any device (workstations or
    print servers) on the local lan segment.

    One thing I did try was to install a new (as in just purchased from a
    vendor in the last 10 days) router yesterday, which had a new IOS
    version (12.3(1a)). However, that didn't solve the problem either, as
    this morning the problem has occurred once already.

    The weird thing is that of the 15 sites on our frame network, this is
    the only site where I'm having this kind of problem. My first thought
    is that maybe it's a problem with the ethernet interface on the remote
    router, but if that were the case I would think that installing a new
    router would resolve the issue, since the ethernet interface is
    built-in.

    Thanks,
    Tim
