Basically
i am following a lab and when it comes to config the frame relay switch router
everything stays as down / down !

basically the FRS is in the centre
has 8 serial outs but im only using 4
1 to R1
1 to R2
1 to R3
1 to R4
the routers them selves are connected to switches and can all ping eachother on the fast eth interfaces

the basic config on the FRS is

hostname FRS
!
frame-relay switching

interface Serial1/1
no ip address
encapsulation frame-relay
clock rate 64000
frame-relay intf-type dce
frame-relay route 102 interface Serial1/2 201
frame-relay route 103 interface Serial1/3 301
frame-relay route 104 interface Serial1/4 401
!
interface Serial1/2
no ip address
encapsulation frame-relay
clock rate 64000
frame-relay intf-type dce
frame-relay route 201 interface Serial1/1 102
frame-relay route 203 interface Serial1/3 302
!
interface Serial1/3
no ip address
encapsulation frame-relay
clock rate 64000
frame-relay intf-type dce
frame-relay route 301 interface Serial1/1 103
frame-relay route 302 interface Serial1/2 203
!
interface Serial1/4
no ip address
encapsulation frame-relay
clock rate 64000
frame-relay intf-type dce
frame-relay route 401 interface Serial1/1 104


and according to the lab
all the info needed on the connected router
is

interface (whatever serial port it is connected to)
ip address x.x.x.x y.y.y.y
encapsulation frame-relay
no shut

but even so when i do that it still shows as down/down on both sides

this is a extract of one of the show conf's on a router

!
interface Serial1/0
ip address 10.0.123.2 255.255.255.0
encapsulation frame-relay
frame-relay lmi-type cisco
!



any ideas why its not working ?
ive attached the network physical and logical diagram

and yes the dce-dte cables are the right way round :P

thanks !

Hi vish112,

Since it shows down/down on both sides I suggest temporarily configuring it as a standard serial connection to confirm there are no problems with the interfaces or cabling. Also, you can do a loopback test to check the serial ports. Assuming that there are no problems with the cabling/interface then configure the frame relay again and check the status with "show frame route" and "show frame pvc".

Here is a good introduction to configuring frame relay:
