Guys just starting CCNP study setup my lab and cant seem to sort frame relay out!

It seems trickier than I remember

I have a 2522 with two 2501 and a 2610. it looks likonly half the interfaces/routes are coming up configs are below

2522 config

interface Serial0
description **** DCE TO RTR 1 ****
no ip address
no ip directed-broadcast
encapsulation frame-relay
clockrate 64000
frame-relay lmi-type ansi
frame-relay intf-type dce
frame-relay route 102 interface Serial1 201
frame-relay route 103 interface Serial2 301
!
interface Serial1
description **** DCE to RTR 2 ****
no ip address
no ip directed-broadcast
encapsulation frame-relay
clockrate 64000
frame-relay lmi-type ansi
frame-relay intf-type dce
frame-relay route 201 interface Serial0 102
frame-relay route 203 interface Serial2 302

interface Serial2
description **** DCE to RTR 3 ****

I have this problem too.

Hello Pete,

are you using real devices or dynamips?

your configuration looks like correct.

is the global command

frame-relay switching

present?

Hope to help

Giuseppe

Ah well I originally configured this then it wasnt working, I tried with and without the global farame-relay switching command on the 2501s etc as I was reading various ways to implement FR and trying some troubleshooting.

I now think it may be a fauty DCE/DTE cable so have some new ones on otder as I am adding significantly to this very old lab.
