RE: Cannot ping own serial int. in a FR lab env??
To ping your own interface you have to do a frame relay map statement to your own ip address to the corresponding DLCI. Otherwise you can't ping your own frame interface. -Original Message- From: Niraj Palikhey [mailto:[EMAIL PROTECTED]] Sent: 26 March 2001 13:21 To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Cannot ping own serial int. in a FR lab env??

Re: Cannot ping own serial int. in a FR lab env??
Run some frame-relay debugging while trying to ping your own serial interface. You will see an "encapsulation failed" message... The trouble is that Frame-Relay, being a layer 2 technology, needs to have a way to translate the IP address of your serial interface (a layer 3 entity) to a layer 2 address (DLCI). Configure a "frame-relay map ip (IP address of local serial int) (dlci)" on the interface and it will work... You need to do the same on the other side. I hope this helps...

Re: Cannot ping own serial int. in a FR lab env??
Thanks, I'll try that and let you know On a sidenote, when I can successfully ping the other side, is it the frame relay switch that's helping to resolve the ip to the dlci configured on the switch with the #frame-relay route command?

Re: Cannot ping own serial int. in a FR lab env??
The frame-relay route command tells the switch which DLCI to advertise on the local interface, and onto which interface to switch received traffic for that DLCI. Inverse-ARP is doing the IP address to DLCI resolution for the routers on each side of the frame-relay link. There are 3 ways to associate a DLCI with layer 3 traffic on a Cisco router: 1. Inverse-ARP 2. frame-relay map statements 3. frame-relay interface-dlci statements The Caslow book as a good description of when you need to use each, and what happens when you combine methods. I hope this helps.

Re: Cannot ping own serial int. in a FR lab env??
Remember that when you Ping your own IP/ interface, you're really sending for a reply from the opposing interface (who has all your information stored). In Frame-Relay- the Ping is stopping @ the switch & if the switch is not mapped with your IP/ DLCI, you do not have this feature available.
