Hello Everyone,
I 'm trying to set up a home lab with a couple of 28XX and 2651XM series routers.
I would like to simulate a frame-relay connection between HQ, Branch1 and Branch2 . All of them are conneced to a PSTN switch (2811 router) via T1 cross over cables. The connectivity is like this.
HQ
|
|
Branch 1 ---> PSTN-WAN <-- Branch 2
I have configured all the routers and FR switch with necessary configuration. However the link between HQ and Branch1 is not coming up. On both the routers I could see the line protocol is down.I have pasted the configuration below. Please advise if am missing anything here. (It is not a cable/port issue)

Hi,
1)
interface Serial0/1/0:0
description ** T1 DATA CONNECTION TO BR1-RTR **
there is no frame route statement here but it should
2) HQ frame-relay interface has Cisco encapsulation but BR1 has got IETF so it won't work.
Regards.

Hi,
Can you clock the DCE side and test again?

Sorry for the late reply Alain...Yes it worked after I made both HQ and BR1 frame relay interfaces as IETF.
Thank you very much for your help !!!!!
