Re: Serial Line is up and line protocol is up ANSW [7:27930]
well you don't always have to put frame-relay map or interface dlci command to configure frame-relay. The most basic one could just be int serial0 ip address x.x.x.x y.y.y.y encap frame-relay exit The router will do the mapping of dlci to ip address by using inverse-arp dynamically. and as far as I know the router will maintain some sort of cache for this mapping you can check it out by using the command sh frame map. >From: "MADMAN" >Reply-To: "MADMAN" >To: [EMAIL PROTECTED] >Subject: Re: Serial Line is up and line protocol is up ANSW [7:27930] >Date: Tue, 4 Dec 2001 12:31:30 -0500 > >not sure what an ip address has to do with LMI nor inverse arp as a >map or interface dlci x will work just fine too.

Re: Serial Line is up and line protocol is up ANSW [7:27930]
not sure what an ip address has to do with LMI nor inverse arp as a map or interface dlci x will work just fine too. Thew bottom line is up and up on a frame circuit does not mean active PVC.

Re: Serial Line is up and line protocol is up ANSW [7:27930]
Yeah if you inverse arp and you change the ip address on one end, the circuit will stay up, lmi will function, but you will not transfer data. - Original Message - From: "MADMAN" To: "Donald" Cc: Sent: Monday, December 03, 2001 2:36 PM Subject: Re: Serial Line is up and line protocol is up ANSW [7:27930] > > Yup, up and up, you got LMI between you and the switch not an active > PVC. > > Dave > > Donald wrote: > > > > Not necessarily you can have a frame connection in an up/up state and not > > transfer data can't you. > > > > - Original Message - > > From: "Gregg Malcolm" > > To: > > Sent: Sunday, December 02, 2001 12:01 PM > > Subject: RE: Serial Line is up and line protocol is up ANSW [7:27930] > > > > > Anil, > > > > > > I'm sorry, my explaination wasn't very good.

Re: Serial Line is up and line protocol is up ANSW [7:27930]
Yup, up and up, you got LMI between you and the switch not an active PVC.

Not necessarily you can have a frame connection in an up/up state and not transfer data can't you. - Original Message - From: "Gregg Malcolm" To: Sent: Sunday, December 02, 2001 12:01 PM Subject: RE: Serial Line is up and line protocol is up ANSW [7:27930] > Anil, > > I'm sorry, my explaination wasn't very good.

RE: Serial Line is up and line protocol is up ANSW [7:27930]
Anil, I'm sorry, my explaination wasn't very good. The answer can't be B since you have no information saying data is being sent and received. The answer A does fit since a frame relay connection is active if int status is UP/UP. As far as the 2nd part, AFAIK not every encap uses keepalives. Frame Relay is somewhat special in that an UP/UP status really means that data COULD be xfer'ed. The case of the broken remote CSU/DSU does not fit this scenarios since keepalives would not be received. The question seems geared toward trying to trick the engineer into thinking that data is being xfered vs. could be. Many encap use keepalives. A few are F/R, ATM, PPP and HDLC (PPP uses an echo). Not sure if all do (probably not). Hope that helps.
