Frame relay configuration

Hi squid3570,

If you issue a sh frame-relay map on the 805 and thr 1600 router. What do you get?

Alright, here is what I suggest. I the dlci's you can change if you want. I test this config on my lab and it should work perfect. I had the 850 connected to the S0 on the Frame Relay Switch and the 1600 connected to S1 on the Frame Relay Switch.

The frame relay switch should a config like this:

interface Serial0 no ip address encapsulation frame-relay clockrate 56000 frame-relay intf-type dce frame-relay route 201 interface Serial1 102 ! interface Serial1 no ip address encapsulation frame-relay clockrate 56000 frame-relay intf-type dce frame-relay route 102 interface Serial0 201

The 850 Router:

interface Serial0 no ip address encapsulation frame-relay ! interface Serial0.1 point-to-point ip address 172.21.3.2 255.255.255.252 frame-relay interface-dlci 201

The 1600 Router:

interface Serial1 no ip address encapsulation frame-relay ! interface Serial1.1 point-to-point ip address 172.21.3.1 255.255.255.252 frame-relay interface-dlci 102

Another thing is that you do not need to enter "ietf" after the interface-dlci command unless you are connecting to non-Cisco equipment. By default, the router will use a Cisco proprietary encapsulation format for the data payload of each packet.

Here are the sh output on the switch:

The frame relay switch config looks good. Can you post the configs for the other two routers?

The only thing that I see that you are missing is that you forgot the set clock rate on the two serial intefaces. As I posted earlier. That can cause issues such as this. Set the clock rate to 56000.

Also do a "no keepalive" on each serial interfaces on the frame-relay switch.

When I do a "keepalive",the interfaces go down!!!!

I want to change the switch! and see

The interface should not go down. Are the physical cables connected properply such as which side is connected to the frame relay switch DCE side of the cable or the DTE side of the cable. Also, when you do keepalive on the Frame Relay Switch side you have to do the same for the Routers, so they can match on both sides. Post the config for Routers.

ok I did a mistake ....it is now ok !!!

Thanks a lot

But when I ping from any of the routers,it give me 32ms for the remote router and 64ms on the local interface.It looks strange!

Hello,

Can you issue a sh interface and show frame-relay pvc and post the results.
