Hi. I have two routers, other is ISP. And between them is frame relay, adtran.

ISP Serial 0 is DLCI 101 and other router Serial 0 dlci 202. Now, which is right;


on ISP; frame-relay map ip 192.168.1.4 101 broadcast ietf

OR

on ISP; frame-relay map ip 192.168.1.4 202 broadcast ietf ??

    read up on frame relay ....

    dlci is the layer 2 address that is only locally significant to what is configured on the frame relay switch so it can be anything from
    i think ??? 1 -1005


    router1
    dlci 102 ---- fr-sw ---- dlci 201 --- router2

    r1
    frame map ip 1.1.1.2 102 other_options

    r2
    frame map ip 1.1.1.1 201 other_options

    only use ietf if you'd like to use ietf encapsulation.
    only use broadcast if you'd like broadcasts to be passed accross the link.
    dont include it if you'd like to unicast only.

    ie if your running rip w/ unicast you dont need broadcast
    if broadcast based rip .. you need to forward broadcasts.
    you can ping 255.255.255.255 to check




    get it ?

    Thanks. Yes, I know the numbers, but I'm not sure how I configure this, which dlci on which router;

    1. on ISP; frame-relay map ip 192.168.1.4 101 broadcast ietf

    and on router2; frame-relay map ip 192.168.1.3 202 broadcast ietf


    OR

    2. on ISP; frame-relay map ip 192.168.1.4 202 broadcast ietf ??

    and on router2; frame-relay map ip 192.168.1.3 101 broadcast ietf

    I guess 1. is right?

    you need to configure the locally significant dlci thats configured on the frame switch at the other send of the serial cable ///

    try using inverse arp and see what the frame switch advertises ?
