    Can you use IP unnumbered in you have your routers in a ring topology
    (serial WAN links, all T1s)?


    .....router A...........router b..........router c...
    . .
    . .
    .....router d.........router e.......................

    all devices having a loopback IP.

    thx

    Thanks Aaron

    What about Cisco works 2000, I guess you will just use the loopback IP
    for management.

    Any ideas about MRTG, would yoou be able to get it to work then?
    Wondering?

  4. No idea about the SNMP stuff. SNMP should look
    at interfaces rather than IP addresses, so it SHOULD
    be cool with this design, but I've heard of some
    SNMP management software that has attitude about
    how you're supposed to address things.

    I don't know about cw2000, earlier versions used matching subnets
    to connect 2 routers, but I believe later versions can use CDP
    too, and then it should be able to work it out.

    MRTG will work just fine, all it needs is a address it can use to
    communicate with the router, which you have.
