Frame Relay
First time doing this and sorry for my ignorance. If I have a 4500M as my Frame Relay cloud. How do I connect my 2501 router to it? Do I just use a DCE to DTE cable? And in the real world would I use a DSU/CSU? Future reference: In the CCIE lab exam do they use DSU/CSU?

Frame-relay
Could someone please clarify something for me about Frame-relay? I had always understood that traffic over frame-relay was unsecure and needed to be encrypted if it was of a critical nature. Is frame-relay always a shared network? I had thought so but I have recently had a someone explain to me that they did not need to encrypt the data because they "owned" the cloud that the pvc ran through. He said that it was a point to point connection and therefore not over a shared network. All of our connections are setup using sub-interfaces and point to point. I still thought that it was over a shared network. This did not make a lot of sense to me. Any help would be appreciated. Any links to good documentation would be helpful as well.

frame-relay
I have spent many hours trying to comprehend the exerpt bellow (from Cisco CD). Still no light. Can someone help? "This command is typically used for subinterfaces; however, it can also be used on main interfaces. Using the frame-relay interface-dlci command on main interfaces will enable the use of routing protocols on interfaces that use Inverse ARP. The frame-relay interface-dlci command on a main interface is also valuable for assigning a specific class to a single PVC where special characteristics are desired." 1. How can the command frame-relay interface-dlci enable the use of routing protocols??!!?? 2. What do they mean by "specific class"? 3. What characteristics are they talking about?

RE: Frame Relay
Layer 2 Seriously, FR is a Layer 2 protocol, as is Ethernet, Token Ring, etc. As those other protocols support numerous Layer 3 (or higher) protocols, so will FR. The beauty of the OSI model is that there is separation of the layers without too much interaction between them. In other words, the Layer 4 datagrams get encapsulated into the Layer 3 packets, which in turn get encapsulated into Layer 2 frames. FR doesn't care for the most part what is "inside" the Layer 3 stuff coming down the pipe. ;-} Rik -Original Message- From: Pierre-Alex [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 01, 2001 8:41 AM To: [EMAIL PROTECTED] Subject: Frame Relay What element in a frame relay packet allows support for multiple protocols?

RE: Frame Relay
I would disagree with the statement below. Ethernet, Token Ring etc are interacting with the upper layers. For example Ethernet II has an Ethertype value that identifies the upper layer for 0x0800 is IP, the same goes for DSAP/SSAP values in the 802.3 header. The OSI layers are somewhat independent of each other except at the borders where they interact. For IP the interaction between the layer 3 and higher uses a Protocol ID field in the header to specify TCP UDP EIGRP etc. Regarding Frame Relay this is done in the encapsulation part. For example if you would use the IETF encapsulation method you (the system) would use a NLPID that identifies the upper layer protocol. For more info on this see http://andrew2.andrew.cmu.edu/rfc/rfc1490.html . Cisco uses a proprietary encapsulation as well where 2 bytes are used for indicating packet type.

RE: Frame Relay
Hi all, As I understand it the frame header has stuff like the addresses, BECN's, FECN's and the like but no place to indicate upper layer protocols even exist. The upper layer stuff is in the data envelope portion of the frame packet(frame) therfore the frame relay service cannot directly push the details to the next (upper) layer. A device must be used to strip the frame header off then read the packet and find where it goes from there. Int this way frame is different to ethernet or token ring in that they have a field that points directly to the upper layers.

RE: Frame Relay
NBMA protocols, per se, do not carry protocol type information in the same that Ethernet does. On the other hand, neither do 802.3, 802.5, or FDDI. The protocol type information for 802.3 is carried inside an 802.2 LLC/SNAP header at the start of the data field. And there are similar mechanisms for WANs: RFC 2427 Multiprotocol Interconnect over Frame Relay. C. Brown, A. Malis. September 1998. RFC 2684 Multiprotocol Encapsulation over ATM Adaptation Layer 5. D. Grossman, J. Heinanen. September 1999. It isn't always necessary, however, to identify the payload protocol. When there is only one protocol in use, or there is little additional cost to each VC so you can configure one VC per protocol, most implementations allow you to configure both ends of a VC to support a single fixed payload protocol type. Saves 5 bytes per frame, which might even be significant on a slow FR link. >Hi all, > >As I understand it the frame header has stuff like the addresses, >BECN's, FECN's and the like but no place to indicate upper layer >protocols even exist.

Hi. Im having some problems understanding frame relay, and would benefit from some good tips! Below are some of the questions I have. 1. Is there a way to allow frames enter your network from 2 routers, so you can analyze the packets? (This is in a back to back configuration only) 2. The router that acts as the frame switch, must it also be the dce end for the clock rate? 3. Why must the dlci's match in a back toback configuration? They need not match when over the link? 4. Why dont I need an ip address in a point to point connection? Thanks a lot. Any tips would be appreciated, and this also will help others!

Re: Frame-relay
When your frame relay service provider assigns you PVC's, they are private unless otherwise specified. The carrier will collect PVC's from different users and transport them over a large pipe together, same as the carriers do with T-1 or subrate circuits. Therefore, it is shared from that perspective, but unless someone has access to that large pipe, the PVC's do not cross across customer boundaries. In other words, no other customer has access to your PVC's. At the end points, the carrier will demux the various PVCs and route them to the proper destinations. - Original Message - From: Dan West <[EMAIL PROTECTED]> To: John Jarrett <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Sent: Wednesday, March 07, 2001 10:15 AM Subject: Re: Frame-relay > AFAIK, this can be true if only one customer is using > all the VCs in a frame network.

Re: Frame-relay
Greetings, My $0.02, Frame is an interface specification. Like X.25. Which means that the 'PVC' only exists between the telco switch and you CPE. Once it hits the telco cloud, its running on SS7 or some other telco (shared, muxxed) longline. Therefore, the data is vulnerable, in a general sense, to telco level 'listening'. Its illegal, and I don't suspect it happens much, but, it can, I suppose. If you buy a leased line, then no one shares your BW, if you simply buy the service at several sites, then, once it hits the switch, its in the telcos 'cloud'. I suppose the telco could listen either way. Encryption seems prudent, if it's not prohibitively expensive.

Re: Frame-relay
It may help to remember that Frame Relay is a packet-switched technology. In fact, if you think about it, "frame relay" sort of means the same thing as "packet switch." Packet switching divides messages into packets and sends each packet individually. The packets may take different routes and may arrive out of order. Although Frame Relay may seem like it's circuit-switched, you really only have a "virtual circuit." You have an actual circuit between your equipment and the provider's equipment at the Central Office or wherever, but after that it's virtual. The core of the provider's network may use a variety of technologies, including ATM, SONET, etc. Anything could happen to your packets. The other common communications method is circuit switching, in which a dedicated channel (or circuit) is established for the duration of a transmission. The best-known circuit-switching network is the telephone system. ISDN is also considered circuit-switching. But Frame Relay replaced the older packet-switched X.25 and retains some of its packet-switching characteristics. Well, I have a bad cold, so I hope I didn't ramble too much.

Frame Relay Problem
Hi All, I hope someone can shed some light on the problem I have come across in the following scenario : Three routers, R1,R2 and R3 all connected via a Frame Relay cloud with a router in the middle doing frame relay switching. The frame switch is _not_ fully meshed. R1 is acting as the hub with R2 and R3 being spokes off R1. Hence there is a PVC betweenR1 and R2 and a PVC between R1 and R3. There is _no_ PVC between R2 and R3. The particular lab exercise here specifies that each router much be able to ping every other router in the frame cloud. BUT the use of the 'frame-relay map' command is forbidden, and only R1 can be configured using a subinterface. As I have it configured R1 can ping both R2 and R3 as expected. However, both R2 and R3 can only ping R1 (the hub) yet cannot ping each other. The question stipulates you should use routing and not Layer2 to Layer3 mapping. A debug on the ping from R2 to R3 shows that there is no map entry for R3 hence encapsulation failed. A look at 'sh frame map' shows there is only 1 entry and it is for R1. This sh frame map is identical on R2 and R3. So the question is, how can I get R2 and R3 to be able to ping each other using routing and not the frame relay map command. It's got two of us here studying for our CCIE stumped, so im hoping someone out there has an idea as to how this can be accomplished. Also, as this is for the CCIE, static routes are not an option.

Your telco provisioned the PVC on the same circuit as DLCI 17, this is evident by the show frame-relay pvc command. You have it configured on Serial 0, which is why it shows up, down. But it is actually on Serial 1.

Frame Relay SVC
Any one knows how to configure Frame Relay SVC switch on Cisco routers? The Cisco configuration guide has examples for SVC on routers but no example for SVC switch configuration. How do you test your SVC router configuration? I have searched the archives, many have asked the questions but I can't seem to find the answer, so I ask again. Thanks!

Frame Relay Fragmentation
I need to turn on FRF.12 on a remote router so that I can make use of the frame-relay ip rtp priority command. However, the PVC that I'll be implementing that on connects to a router that cannot do FRF.12. Does FRF.12 need to be configured on both ends? It seems that it probably only needs to be configured on the end doing the fragmenting, which would be good news, but it I'm not positive about this. Will the near end need to be configured for FRF.12 so it knows how to reassemble those frame relay frames? I'm guessing that I only have to do it on the end doing the work, but I wanted to check before I go break something on a production box. :-) Thanks as always, John ___ Send a cool gift with your E-Card http://www.bluemountain.com/giftcenter/ _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Can someone help? "This command is typically used for subinterfaces; however, it can also be used on main interfaces. Using the frame-relay interface-dlci command on main interfaces will enable the use of routing protocols on interfaces that use Inverse ARP. The frame-relay interface-dlci command on a main interface is also valuable for assigning a specific class to a single PVC where special characteristics are desired." 1. How can the command frame-relay interface-dlci enable the use of routing protocols??!!?? 2. What do they mean by "specific class"? 3. What characteristics are they talking about?

Frame Relay PVC
I have a intermittent problem (about a dozen times a day) where a PVC goes from the active to inactive state. It used to happen maybe once a week. I have not changed anything on either router. Furthermore, my other PVC's are unaffected. I did a debug of the lmi packets and the output is below.

In his example of partially meshed network ( routers A B C D, A connects to B C D and A is only the router connected by B C D). I understand why we need subinterfaces on router A. But why we he has subinterface set on routers B C D? Is it because of setup consistency or what is the catch?

on Frame Relay
Folks I have couple of questions on Frame Relay. When they say CIR is 64Kbps and the port is 256Kbps in a 64/256 FR link, what does that mean? Do I get CIR all the time and do I also get the port bandwidth all the time? How does this work? Do the service providers have the port bandwidth for each link or it is shared across? How does the pricing work, if somebody bursts upto the port speed all the time, does he get billed more? Cheers, Rayappa.

FRAME RELAY PROBLEM
I have got a problem with FR Config Running OSPF. Router A & B are connected to C & D over FR PVC but they don't have to talk to each ther. It means A connected to C & D and B is also connected to C & D. I am using FR Subinterfaces with pt-to-pt. What is happening that sometime I am able to ping to router C & router D subinterfaces from router A but sometimes i don't get any response. I am even unable to ping sub-intf of Routers from within the routers. See sample config of one of the routers that i have: interface Serial0 no ip address ip directed-broadcast encapsulation frame-relay ip ospf network broadcast no ip mroute-cache ! interface Serial0.1 point-to-point ip address 131.18.19.185 255.255.255.252 ip directed-broadcast ip ospf network broadcast frame-relay interface-dlci 310 ! interface Serial0.2 point-to-point ip address 131.18.19.189 255.255.255.252 ip directed-broadcast ip ospf network broadcast frame-relay interface-dlci 210 This is config of router B connected to C & D and subintf of C &D are on same subnet as subintf 0.1 and 0.2 on this router. Is pt-to-pt with sub-intf OK for this scenario? Any suggestions... What is the possible cause of problem?? Why I am even unable to ping local subintface from within the router??

If you had 3 locations in a hub and spoke topology, then you would want two pvcs going to each site...(using subinterfaces), how do the numbers change as you add remote sites... e.g. if you add the 4th site, do you have to add a pvc to every other site?, totalling 3 pvcs/subinterfaces ? so would that mean if you had 100 sites it would require n-1 (99) pvcs/dlcis/subints per location...? i may be way off -thanks = ciscocabanaboy, CCNP-Voice, CCDP, MCSE, CNX, A+, N+, I-net+, BOFH... __ Do You Yahoo!?

QUERY ON FRAME RELAY: DISABLE FRAME RELAY INARP [7:15586]
Hello all, I found something wierd in my scenario. I configured my FR switch for fully meshed. I have three routers, A (hub) , B and C as the spokes. But I want to configure the three routers ONLY with partial mesh (hub and spoke), on router A , I configure on Physical interfaces. on Router B and C, I try with sub interface and DISABLE inverse arp (to prevent ip address resolve from B directly to C and vice versa).. But when I "show frame-relay map) on either B and C, I still can see resolved IP address with pvc (DLCI) directly connected to each other ( B and C).. and also, when I " show frame-relay pvc", I still can see that the other PVC is considered as "USAGE" any one can figure out how can I over come this one..? tx, Grad _ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=15586&t=15586 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Question about frame-relay map statements and frame relay inverse arp
Dear Group, I have been trying to duplicate the problem where if you enter a frame relay map stament in a frame realy interface that is also using frame relay inverse arp that inverse arp will be disabled for specific protocol for that specific DLCI specified in the frame relay map statement. I have reloaded my router, yet the interface still does inverse arp and is able to keep the mapping to the hub and also ,of course, still has the frame relay map statement. My question is this, Has anyone else run into this? Also, I am running 12.09 code and I am wondering if this is something that has been worked around on the 12.09 code. Here is the interface config for the frame relay interface: interface Serial0 ip address 192.168.10.10 255.255.255.0 no ip directed-broadcast encapsulation frame-relay frame-relay map ip 192.168.10.5 211 after the reboot I get this for the "show frame-realy map" : Satellite2R5#show frame-relay map Serial0 (up): ip 192.168.10.1 dlci 211(0xD3,0x3430), dynamic, broadcast,, status defined, active Serial0 (up): ip 192.168.10.5 dlci 211(0xD3,0x3430), static, CISCO, status defined, active According to Caslow books and other publication the spoke router should loose connectivity to the hub router since since it is using frame relay inverse arp to map to the hub router. I have a 2523 as my frame relay switch. Anyway, I still maintain an inverse arp mapping to the hub and do not loose connectivity to it. Anyone have any input on this?

Another Frame-relay issue..

The lab equipment in use; AGS+ : 11.0(22) Frame-relay cloud R1 2501 : 12.0.9(15) Hub sub-interface(s0.1 P-t-P1.1.1.1), and = (s0.2, ip 2.2.2.1) Multipoint R2 2502 : 11.3.(11a)T1 Spoke - Physical interface, ip 1.1.1.2 R3 2502 : 11.3.(11a)T1 Spoke - Physical interface, ip 2.2.2.2 R4 2520 : 11.3.(11a)T1 Spoke - Physical interface, ip 2.2.2.3 After setting the frame circuit and the Hub and spoke routers the HUB = specific local DLCI's come up and go active on the frame switch, the = spoke DLCI's go active the inactive, then deleted. I looked at every = thing that made sense,=20 1)Is the HUB - is the interface-dlci command using the correct dlci's , = Yes! =20 2) At the spokes is the encapsulation type(frame relay) configured, Yes! 3) Is the ip (L3) configured on all devices, Yes! Ok, a "clear frame inverse-arp" and a good sign I get an arp for R2 on = the hub! A second look shows R2 has no mappings and the pvc is = inactive. No matter what I did nothing. No this is really weird... Before I started this lab I did a "wr erase" = on all the routers. I proceeded to do a "wr mem" for the first time = since entering all my commands for my frame relay setup on the HUB, and = out of nowhere all the Spoke DLCI's go active and everything works like = it's suppose too. No, in everything things I've read it says that the commands go active = as they're entered, however here it seemed to require me to wr mem for = the circuit to come up.

Re: Frame Relay Charges
I'm not sure who the provider is but 0 CIR sounds like "Sprint-speak". Most service providers won't allow or recommends against 0 CIR but on the other hand, Sprint pushes it. We are currently using 0 CIR and I think the quality has been good and we haven't had a whole lot of dropped packets. In fact, I think they still guarantee 99% delivery up to port speed which is pretty good specially compared to most providers 99.9% delivery up to CIR and no guarantee beyond that.

Re: Frame Relay Charges
That's true. All packets will be DE marked but 99% of the time, these DE marked packets will get through - that's what our SLA with them is. Their reason for this is that their network is "bleeding edge" and that they are willing to create an SLA for 0 CIR as compared to most providers who won't promise you anything. You can pay, like i said, for CIR and their SLA will guarantee 99.99% packet delivery up to CIR.

RE: Frame Relay Charges
Let me just say this - I work for Sprint Local Telephone Division (LTD) and we do not do 0 CIR. Sprint Long Distance Division (LDD) does do 0 CIR. It is just a difference in philosophy. I have spoken with some LDD engineers and their justification is that their network is so robust that there is no need for an actual CIR. It always surprises me that the sales guys don't go nuts at this because CIR is added revenue for them!

RE: Frame Relay Charges
0 CIR, must be SPRINT. How FR providers base their charges? It depends on the provider and also if you are talking about Internet access or private frame. Some charges nothing for bursting over the CIR, others charges based on how much and how long you bursted over CIR. You need to ask the provider for the detail of their charges. 0 CIR for 8-5, it depends on the type of data you want to transmit. Example: You can't afford frame dropping if you transmit video or voice.

RE: Frame Relay Charges
Hi, To cut costs some people use Zero CIR. BUT, this might connect to a remote end that bases it's utilisation on CIR. For example, a supplier might run a service from the core to a frame switch at 2Meg with a CIR of 2Meg this will then cope with the entire commited range to the serial port. Say you have 10 people with Zero CIR connected and 4 with 512K. The switch sees the ZERO with DE bits (all packets) what happens. On the floor they go. Ring the supplier he might be symathetic to your problem. My guess is he will not only recommend you up your CIR but also charge you for the inconvenience. Remember there are two ends to all of this plus a middle you have no control over. The CIR gives you the little control you might like. The secret with CIR is to cover yourself without buying more than you need. Just some thoughts.

Re: Frame Relay Charges
I work for Sprint and we use the 0 CIR approach with our customers. I don't know if it's Sprint you are talking to, but we have never had any customers complain about frame performance. Personally, I like to have some CIR, even if it is just 16k, but that comes from my administrator experience prior to Sprint. Because Sprint is an IXC and also a LEC in a lot of cities, Sprint has so much bandwidth they can't oversubscribe their network even if they wanted to. The only time I would suggest a certain level of CIR is if you plan on moving Voice traffic over this frame circuit. Otherwise, 0 CIR is fine. Any IXC will tell you that "0 CIR is really a marketing tool" and it is. Sprint uses over 200 Nortel Passport 15000 switches in their backbone interconnected with OC192 ATM - so with that in mind, believe me when I say Sprint has so much bandwidth they can't even us it all. It's true. If this was another carrier, ask other customers how they like their service.

RE: Frame Relay Simulator
Are you looking for a FR simulator or a WAN simulator? There is an awesome product out on the market by a company named Shunra called the 'Storm' and the 'Cloud'. You can manipulate network latency, standard deviation, packet loss etc. in a variety of forms. Whats really cool is that it integrates with Visio and all of the admin(aside from compiling the kernel), take place from that interface. The only problem is its not cheap (around $20K) new; buts its way cool. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Bradley J.

Re: Frame Relay Problem
If you could post the configs it would help, but here's some ideas to try. Are you sure have inverse ARP working? Have you tried a static route to R3 (from R2) gatewayed to R1's IP and the same on R3 to R2 via R1's IP? Look into Proxy ARP. Just a thought, I've never tried this but, is there a way to make a static ARP entry?

Re: Frame Relay Problem
Unless I'm mis-reading you here this is the correct behavior for a partial mesh. Unless you provide a full mesh you won't get dynamic mappings for both spokes. Also, I assume the PVC from R1 to R2 is one subnet and the PVC from R1 to R3 is another subnet--Frame relay and Inverse ARP alone can't route between them. So if you can't get a PVC between R2 and R3...then run any routing protocol on all 3 routers and you should be able to ping from R2 to R3 and vice-versa (RIP will work fine to prove this point.)

Re: Frame Relay Problem
Sounds like all you need to get your branch traffic to the next hop (hub router) where the hub router will route it for you because it knows of the routes to all destinations. You could use static routes or route maps with the next-hop parameter to do this. - Original Message - From: James Wilson <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]> Sent: Sunday, November 26, 2000 5:50 PM Subject: Frame Relay Problem > Hi All, > > I hope someone can shed some light on the problem I have come across in the > following scenario : > > Three routers, R1,R2 and R3 all connected via a Frame Relay cloud with a > router in the middle doing frame relay switching.

Re: Frame Relay Problem
Nope, all one subnet. i.e all interfaces are on the 10.1.X.X/16 subnet Hence the problem. Im well aware this is the normal partial mesh behavior and that its quiet easily rectified using map statements... but for this particular setup it requests the use of routing and not frame relay map statements.

RE: Frame Relay Problem
Then try using policy routing to set the next-hop for all packets to go to the hub which has a route to the other spoke. Then the other spoke should have the same type of route-map. Using this method you won't need to change the routing table, but change the packets themselves. Don't forget that if you are doing this from a local ping on the router you will need to enable the route-map with the local policy command. Regards, Aaron K.

Re: Frame Relay Problem
Ah...now I need more info. Below you stated "only R1 can be configured using a subinterface"--so that's my first question: Is it configured with sub-int's, one for ea PVC? If yes, and they are configured as point-to-point then I believe that each separate PVC is required to be on a separate subnet since the router treats each as a separate interface. In this scenario my original response will work. If no, then are you using one multipoint subint on R1 the Hub router? If so, one subnet works for all three interfaces but I believe you'll need map statements at the spokes. I understand this isn't an option. So please provide more details...

RE: Frame Relay Problem
Title: RE: Frame Relay Problem Maybe I'm missing something, but in looking at your config and cross-referencing the rules of the lab, I can't understand why you didn't just create two subinterfaces on R1. -Original Message- From: James Wilson [mailto:[EMAIL PROTECTED]] Sent: Sunday, November 26, 2000 5:50 PM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: Frame Relay Problem Hi All, I hope someone can shed some light on the problem I have come across in the following scenario : Three routers, R1,R2 and R3 all connected via a Frame Relay cloud with a router in the middle doing frame relay switching. The frame switch is _not_ fully meshed. R1 is acting as the hub with R2 and R3 being spokes off R1. Hence there is a PVC betweenR1 and R2 and a PVC between R1 and R3. There is _no_ PVC between R2 and R3. The particular lab exercise here specifies that each router much be able to ping every other router in the frame cloud. BUT the use of the 'frame-relay map' command is forbidden, and only R1 can be configured using a subinterface. As I have it configured R1 can ping both R2 and R3 as expected. However, both R2 and R3 can only ping R1 (the hub) yet cannot ping each other. The question stipulates you should use routing and not Layer2 to Layer3 mapping. A debug on the ping from R2 to R3 shows that there is no map entry for R3 hence encapsulation failed. A look at 'sh frame map' shows there is only 1 entry and it is for R1. This sh frame map is identical on R2 and R3. So the question is, how can I get R2 and R3 to be able to ping each other using routing and not the frame relay map command. It's got two of us here studying for our CCIE stumped, so im hoping someone out there has an idea as to how this can be accomplished. Also, as this is for the CCIE, static routes are not an option.

Re: Frame Relay Problem
Your suggestions are good, unfortunately i have already tried most of them and other break the rules of the lab Here's a run down : - R1 is currently configured with 1 multipoint subinterface with multiple frame-relay interface-dlci commands. - The rules state only 1 subinterface can be used, and also state only the one 10.1.0.0/16 subnet can be used so that rules out the multiple subnets. - The lab stipulates the ip addresses for R1, R2 and R2 be 10.1.1.1/16, 10.1.1.2/16, 10.1.1.3/16 respectively. So there goes the multiple point to point interfaces / multiple subnets idea. bummer. As you said, Map statements are not to be used. The direct quote from the lab is "Also, one of the problems in this lab [i.e r2 not being able to ping r3] can be solved with multiple frame map ip statements, but this is not the solution i want you to use. Solve the problem with routing, not layer 3 to layer 2 mapping". Hence ruling out any static frame mapping or arp type solutions as these are all layer 2 to layer 3 mapping techniques.

RE: on Frame Relay
Title: RE: on Frame Relay The port itself can handle up to 256K; that's the port speed. You're paying for 64K (CIR), which is what you'll get on average. You will occasionally burst up to 256K when there is no other traffic on the circuit (it is shared bandwidth with other frame relay subscribers). This bursting is figured into the pricing (remember, you'll average 64K throughput, even though you may not get exactly 64K all the time). If you burst over your CIR for more than your alotted time slot (remember, they expect you to burst every once in a while) your packets will be marked as discard eligible and will be preferencially discarded if another customer is trying to transmit within CIR, such that the port would not be able to handle your extra data (you'll be relegated back to your own CIR). The pricing can be done differently, depending on the carrier. Some will bill you for your CIR plus any actual usage above CIR. Others allow you to burst up to the maximum available bandwidth as long as there is no other traffic for no extra charge. There's also a new animal on the frame relay front called 0-CIR, which means you don't elect a CIR at all, and pay only for actual usage. If this has been completely confusing, then the telco has done their job well. I think half the time they actually want their customers not to understand their pricing. Anyway, pardon my kvetching. =) Hopefully the technical details are helpful to you. - Don -Original Message- From: Rayappa Mayakunthala [mailto:[EMAIL PROTECTED]] Sent: Monday, November 20, 2000 11:23 PM To: [EMAIL PROTECTED] Subject: on Frame Relay Folks I have couple of questions on Frame Relay.

With FRF.12 UNI, frames are reassembled on ingress to the network, in other words at the service provider's switch. Frames cross the network unfragemented. The UNI frame format looks like: Fragmentation Header/Frame Relay Header/Payload (Fragment)/FCS. FRF.12 UNI is often sufficient to handle the problem of large frames taking a long time to leave the router, thus causing a backup for small voice frames or frames for interactive or real-time applications. Last I heard, Cisco didn't support FRF.12 UNI, though. That could have changed. With FRF.12 end-to-end fragmentation, frames traverse the network as fragments and are reassembled at the terminating router. So both routers would have to support it. The frame traverses the complete network looking like this: Frame Relay Header/Fragmentation Header/Payload (Fragment)/FCS. FRF.11 Annec C also does fragmentation. It is end-to-end. The difference is that Annex C allows for a subframe header which supports many different channels. The frame looks like: Frame Relay Header/Subframe Header/Fragmentation Header/Payload (Fragment)/FCS. As you can see from the frame formats, you have to be careful to configure the routers (and switches) properly, obviously.

Re: about frame relay
Hi, The DLCI is assigned by the supplier. It has only local significance. OK you get a line installed and it has a a number to indicate to the supplier and switch what the physical service (for want of a better word) is. Over this service runs one or more "Switched" circuits. These can be define as permanent PVC or switched SVC. These circuits require a point to map to that is the DLCI. You therefore map the DLCI to an interface on your router using the commands you have below. (substituting the DLCI assigned by your supplier) That's the way I understand it. Hope it helps.

Re: about frame relay
1. you don't need the 'frame-relay map' command, because you've implemented the 'frame-relay interface-dlci' command. These commands are used to map the level-3 address (IP addr in this case) to your level-2 address (the dlci). You use one or the other command. 2. DLCIs are assigned by the network provider. You need to be sure that DLCI 16 really designates the PVC to Boston. 2a. The frame relay provider provisions the DLCI for each PVC, on each end of the PVC.

frame-relay interface-dlci
I have spent many hours trying to comprehend the exerpt bellow (from Cisco CD). Still no light. Can someone help? "This command is typically used for subinterfaces; however, it can also be used on main interfaces. Using the frame-relay interface-dlci command on main interfaces will enable the use of routing protocols on interfaces that use Inverse ARP. The frame-relay interface-dlci command on a main interface is also valuable for assigning a specific class to a single PVC where special characteristics are desired." 1. How can the command frame-relay interface-dlci enable the use of routing protocols??!!?? 2. What do they mean by "specific class"? 3. What characteristics are they talking about? Please explain AND illustrate each point...
