Frame-Relay on routers back-to-back ?

    Sorry if this question sounds stupid to you good old veterans out there, but I'm new to this site and I'm also new to the CCNA course.

    Anyway I'm currently studying frame relay and I'm trying out manual resolutions on three routers back-to-back.

    Somebody told me you could use one of the routers to simulate a frame-relay switch. I've tried that, but it isn't working for me so far. As soon as I start to configure encapsulation on any of the routers, the protocols go down. Sometimes they wait until I actually configure the LMI-type before they go down, but they still go down anyway.

    In case you're wondering, one of my routers is a 2620 and the other two are 3620s. Actually they belong to my housemate who's away working abroad at the moment.

    I also have at my disposal 2 catalyst 3550 switches. But I don't see how useful any of them could be in this instance, since neither of them have any serial interfaces.

    I know I'm probably doing something wrong. Problem is, I don't know what.

    Can anybody help ?

    Below are the configs and show commands of one of the 3620s, the one I'm trying to use as a frame-relay switch, that has serial interfaces connected to each of the other routers.

    Hello,

    Your config is incorrect. Here is a simple example of configuring a router as a frame relay switch:

    frame-relay switching
    int s1/0
    no ip add
    encap frame
    clock 64000
    frame intf-type dce
    frame rou 100 int s1/1 200
    int s1/1
    no ip add
    encap frame
    clock 64000
    frame intf-type dce
    frame rou 200 int s1/0 100

    The above should get you started. Note the global "frame-relay switching" command. Also, note that the frame-relay switch is the dce side of the connection. Then configure the other routers to connect to either side of the above frame switch and test it out.

    Thanx Spice-Weasel. That was a big help. I understand most of it except those little bits at the end there.

    Frame rou 100 int s1/1 200
    Frame rou 200 int s1/0 100

    What is that ?

    Sorry for being a pain, but I've only been studying this for a few weeks.

    Mucho thanx.

    No problem, glad to help. My post, above, was brief as I was in a hurry.

    The commands:
    frame rou 100 int s1/1 200
    frame rou 200 int s1/0 100

    - are used to create a static route for PVC (permanent virtual circuit) switching. The command maps an incoming dlci and interface to an outgoing dlci and interface. The command is expanded, below:

    frame-relay route 100 interface serial1/1 200

    The command essentially says: frame-relay frames coming into the interface, with a dlci of 100, are to be sent out interface serial1/1 with a dlci of 200

    Of course, the routers on either side of the frame-relay switch need to be configured with the correct dlci. You can make many static routes, I just put only one in the example for simplicity. Once you have a basic working setup you can experiment with different lmi types, keepalives, subinterfaces, NNI, maps, QoS, shaping, etc. There is plenty to try out, have fun. Try things and make mistakes, and get used to the show and debugs, that is the best way to learn. ;)

    Hi Spice,

    I've just been practicing what you showed me and I think I'm making a little progress. I even slapped on a couple more DB60s to add a little zing to my zest.

    Anyway, this is what I came up with. Looks a little messy and there's quite a few more kinks to iron out here and there, but it's a start, right ?

    Thanks for helping out.
