Frame-relay PVC Issue - CISCO, status deleted

Unanswered Question
Oct 17th, 2010

Hi,

Been pulling my hair out on this one!!  OK in my lab environment I have a hub (R1) & spoke (R2 and R3) network with a frame relay switch (R6). For some reason, I am seeing CISCO, status deleted on the spoke routers. This is not allowing me to PING. Here's a quick look at all the configurations;

R6 - Frame Relay Switch

interface Serial0
no ip address
encapsulation frame-relay
logging event subif-link-status
logging event dlci-status-change
clock rate 56000
no fair-queue
no frame-relay inverse-arp
frame-relay intf-type dce
frame-relay route 122 interface Serial1 221
frame-relay route 123 interface Serial2 321
!
interface Serial1
no ip address
encapsulation frame-relay
logging event subif-link-status
logging event dlci-status-change
clock rate 56000
no frame-relay inverse-arp
frame-relay intf-type dce
frame-relay route 221 interface Serial0 122
!
interface Serial2
no ip address
encapsulation frame-relay
logging event subif-link-status
logging event dlci-status-change
clock rate 56000
no frame-relay inverse-arp
frame-relay intf-type dce
frame-relay route 321 interface Serial0 123

Deleted seems to indicate your frame switch isnt passing down the DLCI to you.

1) Have you made sure "frame-relay switching" is configured on R6?

2) On all three routers do: show frame-relay pvc | i ACTIVE

3) On all three routers do: show frame-relay map


Once you post that data back, we can help you further.

Thanks!

Tim

Hi Tim,

Sorry, forgot to show that "frame-relay switching" was already configured on R6. All the other commands you asked for were already in my initial post!

I decided to erase the configuration on all routers and the FR switch. Starting again, I managed to get them showing as active.

This is what I believe was the problem:

When I enabled encapsulation grame-relay, inverse arp was enabled and may have paired incorrectly. So I shutdown the serial interface, cleared all inarp entries, removed the encapsulation frame-relay settings of the serial interface, disabled inverse-arp and reconfigured the interface as normal. After that I managed to see the spokes show up as active.

I also added 2 interface-dlci references on the hub router which I forgot to.

I realize this post is pretty old, but I just wanted to give everyone a heads up that what worked for me was just deleting the subinterfaces I was using and rebuilding them. It also seemed that I had to assign the IP address first before configuring the interface DLCI. It's a little different than the listed problem, but hopefully this helps someone.
