Frame Relay PVC through another router

Hi,

I have two routers connected to each other via a 2mb leased line. I need to build a FR PVC between these two routers over the leased line - any idea how I do this? I know how to do it back-to-back and I've seen the doc on CCO, it's just that this isn't back-to-back, so I presume I have to do something different.

Also, once I have this working, I have another router connected to one of the routers above via a DCE/DTE X.21 cable. I need to build a FR PVC from this router through the directly connected router to then terminate on the remote router at the other end of the leased line. I don't know how to do this, the PVC needs to run in parallel with the first one.

All routers are of course Cisco.

Any help greatly appreciated.

Re: Frame Relay PVC through another router

Hi,

I was thinking of frame-relay switching, which can be configured on a cisco router as follow:

conf t

frame-relay switching

interface serial 0

encapsulation frame-relay

clock-rate 64000

frame-relay intf-type DCE

frame-relay route 100 interface serial 1 101

! DLCI 100 incoming, out S1 DLCI 101

Hi,

you can use this config to make the "middle" router to work as FR switch:

conf t

frame-relay switching

interface Serial0

no ip address

encapsulation frame-relay

frame-relay intf-type dce

frame-relay route 16 interface Serial1 16

!

interface Serial1

no ip address

encapsulation frame-relay

frame-relay intf-type dce

frame-relay route 16 interface Serial0 16

Regards,

Milan
