Re: Problem Pinging FR Interface - What is Going On? [7:36743]
The short story is that the local interface does not have a layer three to layer two mapping. Put a frame relay map statement in for the local interfaces IP and you'll be able to ping the local IP. PS: If you use point-to-point subinterfaces you'll have no problem pinging your own interface due to INARP. K.K. From: Karl Brusen Date: 2002/02/27 Wed PM 07:08:02 EST To: [EMAIL PROTECTED] Subject: Problem Pinging FR Interface - What is Going On? [7:36743] I was working with FR in my home lab, and I ran into an interesting problem. This is the first time I've set up a router to function as a FR switch. Here's the scenario. I am using a 2524 with two five-in-one serial modules as the FR switch to connect two routers with fixed serial ports, a 2503 and a 2509. The PVC is up and active. I can ping from each router, through the FR switch to the router on the other side, but I cannot internally ping the FR interface of the router I am pinging from. After checking around a bit, I learned that pinging a serial interface of the router originating the ping works differently than pinging an ethernet interface. Apperently, serial interfaces cannot responded internally to an interally generated ping -- the ping actually goes out on the wire and comes back. I don't completely understand this, but it is clear the the ping does travel through the external cable. So can anyone tell me why the internal ping to the FR interface doesn't work. It isn't a big deal, but I would like to understand what is going on. Is there a problem with the way I have configured the 2524 as a FR switch? Here are the configurations.

Re: Problem Pinging FR Interface - What is Going O [7:36743]
You the man! That did it. Under the 2503 s0 I put in a statement: frame-relay map ip 172.16.17.1 301 This maps the interface's own IP address to the local DLCI. I can now ping the interface. I now understand what is going on, but it seems a bit odd that you have to tell the router how to find its own interface. I learned something I didn't know before. That's what it's all about. Thanks, Scott.

RE: problem on FR
PVC deleted - your router does not see the DLCI that you have configured ( Check to see if you are getting lmi from the switch, if yes then check your DLCI's or call telco) PVC inactive - your router sees a DLCI on the frame relay but something is stopping it from becomming active (check the configutation on both ends ) -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of news.groupstudy.com Sent: Wednesday, January 03, 2001 1:16 AM To: [EMAIL PROTECTED] Subject: Re: problem on FR What is the status of the main interface you are configuring this Frame-relay subinterface on?

Re: problem on FR
Hi, I was under the impression that when you get "Deleted" there is no PVC between you and the frame switch. You might still see an LMI but the DLCI you think you have is not connected at the frame switch. When you see the PVC as "inactive" this indicates the DLCI to the frame switch is configured ok but the remote site is either down, the DLCI on the remote site is not configured or you are trying to get to the wrong DLCI on the remote site. Hope this helps.
