Subject: Frame Relay home lab question

Hello,

I'm having some issues setting up a home lab for Frame Relay and I'm hoping some of you gurus can help me out here. If the routers and sub-interfaces look familiar I'm going off of IPExpert labs...

For the Frame Relay switch I'm using a Cisco 3725 which has two VWIC-2MFT-T1 cards installed. For the routers I have 1 Cisco 2612XM and a Cisco 2620, each router has a WIC1-DSU-T1 card installed.

I made two T1 crossover cables using pins 1-2 and 4-5 which are reversed on the other end. To test the cables I plugged them directly into WIC cards on some other spare routers and brought up the interfaces without issue. At this point I thought I would connect the routers to the frame switch and see what happens...

On the frame switch I enabled frame relay using the "frame-relay switching" command and issued the following commands on the VWIC-2MFT-T1 cards to create the serial interfaces

controller T1 0/0
 framing esf
 linecode b8zs
 channel-group 0 timeslots 1-24
!
controller T1 0/1
 framing esf
 linecode b8zs
 channel-group 0 timeslots 1-24

Now this created the following serial interfaces which I configured as follows

Serial0/0:0
Serial0/1:0

interface Serial0/0:0
 no ip address
 encapsulation frame-relay
 logging event subif-link-status
 logging event dlci-status-change
 clockrate 56000
 no frame-relay inverse-arp
 frame-relay intf-type dce
 frame-relay route 204 interface Serial0/1:0 402

interface Serial0/1:0
 no ip address
 encapsulation frame-relay
 logging event subif-link-status
 logging event dlci-status-change
 clockrate 56000
 no frame-relay inverse-arp
 frame-relay intf-type dce
 frame-relay route 402 interface Serial0/0:0 204

On the two routers I configured the interfaces as follows

R2

interface Serial0/0
 no ip address
 encapsulation frame-relay
!
interface Serial0/0.24 point-to-point
 ip address 150.100.24.2 255.255.255.0
 frame-relay interface-dlci 204

R4

interface Serial0/0
 ip address 150.100.24.4 255.255.255.0
 encapsulation frame-relay
 keepalive 10
 frame-relay interface-dlci 402

And this isn't working :(

I checked the lights on the WIC's and they have CD lights with no alarms and the interfaces are up / protocol down

The output from show frame pvc or map on either router isn't so good either

R4#show frame pvc

PVC Statistics for interface Serial0/0 (Frame Relay DTE)

              Active Inactive Deleted Static
  Local 0 1 0 0
  Switched 0 0 0 0
  Unused 0 0 0 0

DLCI = 402, DLCI USAGE = LOCAL, PVC STATUS = INACTIVE, INTERFACE = Serial0/0

  input pkts 0 output pkts 0 in bytes 0
  out bytes 0 dropped pkts 0 in pkts dropped 0
  out pkts dropped 0 out bytes dropped 0
  in FECN pkts 0 in BECN pkts 0 out FECN pkts 0
  out BECN pkts 0 in DE pkts 0 out DE pkts 0
  out bcast pkts 0 out bcast bytes 0
  5 minute input rate 0 bits/sec, 0 packets/sec
  5 minute output rate 0 bits/sec, 0 packets/sec
  pvc create time 00:02:07, last time pvc status changed 00:02:07
R4#

So, I'm pretty stuck here.
Thanks in advance with any help you can provide me here!
