Need help with frame relay switch configuration

[asimkamran]

Hello everybody,

Here's my setup:

R1 (Hub) has two serial connections to FR switch, R2 and R3 each have one serial connection to FR switch.

Now my question is how can go about assigning the DLCIs? When I try to apply the following command frame-relay route 221 interface serial 1/0 101 and frame-relay route 221 interface serial 1/0 101

it doesn't acccept it saying that you can't have two dlci's assigned to same interface.

If anybody can refer me to any configuration doc for this same scenario I would appreciate.

You can only use one dlci per interface at least that you create sub-interface you can asign two dlci or more per interface.
