Frame Realy Lab problems

    Hi Everyone,

    I'm sure someone can shed some light on the this, it's doing my head
    in! I've been at it for 7 hours and I'm sure there must be some decent
    explaination.

    I'm setting up Frame Relay Home Lab as per Chris Bryant, here is the
    switch config:

    http://www.thebryantadvantage.com/Frame Relay Switch.htm

    All is well apart from R2, where I have configured a multipoint
    sub-interface 1.123

    Sometimes I see (looped) when doing a show int and on the 2610 that
    I've configured as a Frame Relay switch, I see this, it's continously
    up and down.


    FRAME_SWITCH# sh i
    08:27:37: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/2,
    changed sta te to down FRAME_SWITCH# sh i
    08:27:47: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/2,
    changed sta te to up FRAME_SWITCH# sh i
    08:27:56: %FR-5-DLCICHANGE: Interface Serial1/2 - DLCI 221 state
    changed to ACTI VE FRAME_SWITCH# sh i
    08:28:06: %FR-5-DLCICHANGE: Interface Serial1/2 - DLCI 221 state
    changed to INAC TIVE FRAME_SWITCH# sh i
    08:28:07: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/2,
    changed sta te to down FRAME_SWITCH# sh i
    08:28:17: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/2,
    changed sta te to up


    I have switched cables, also gone from S0 to S1 but no joy.

    Would really appreciate any input to help.

    Thanks a million.

    Try

    interface Serial1.123 multipoint
    no ip route-cache
    frame-relay map ip 192.168.1.100 221 broadcast
    frame-relay map ip 192.168.3.100 321 broadcast

    Note that the secind map statement maps DLCI 321 to 192.168.3.100 321.

    Chris Bryanat who wrote the papers says this:

    "notice that even that I'm going to 2 different IP addresses I use the
    same DLCI, that's because, for data to get to router 3 (3.100) it has
    to go through router 1 (2.100) in the first place, it's a spoke to
    spoke communication"

    The topology is HUB/SPOKE - 1.100 & 2.100/3.100

    In the link that you provided in your first post, the FR switch
    configuration does not seem to support this spoke to spoke
    communication that you are referring to. The part you quote probably
    refers to a different set-up where the FR switch is also configured to
    allow the spoke to spoke communication.

    I would suggest that you first get the simple huband spoke
    configuration working and then work with variations of that config to
    get the spoke to spoke working.

    Thanks Cisco da Gama,

    One error I had was:

    LMI DLCI 1023 LMI type is CISCO frame relay DTE

    instead of:

    frame intf-type dce

    So now that's sorted but still having some issues, trying to get my
    'mentor' to telnet in and see what the deal is.

    Thanks for your help,
