Re: Cisco frame-relay question [7:71500]
I think frame-relay local-dlci is used for specifying which PVC should be used on a interface, or in other word tie a interface to a PVC, especially when using sub-interface. When using physical interface, you may use frame-relay map command or inverse-arp in case you have only one PVC for that interface MNThC nh Support Division Vietnam Datacommunication Company (VDC) Wilmes, Rusty wrote: It looks like it's used when LMI isn't available http://www.cisco.com/en/US/products/sw/iosswrel/ps5187/products_command_refe rence_chapter09186a008017cf53.html#1059567 Note The frame-relay local-dlci command is provided mainly to allow testing of the Frame Relay encapsulation in a setting where two servers are connected back-to-back.

Frame Relay question [7:65659]
I am working with the test out simulator. LAX 11.0.0.2--frame cloudsfo 11.0.0.1 In the frame relay module there is an exercise to connect 2 routers through a frame relay cloud. Initially, the LAX router is using inverse arp to do the mapping. A show frame map yields Serial 1 (up): ip 11.0.0.1 dlci 100 (0x64,0x1849, dynamic,broadcast,,,status defined,active After turning off the frame-relay inverse-arp and clearing the cache, I enter a static mapping frame map ip 11.0.0.1 100 now the show frame map yields Serial 1 (up): ip 11.0.0.1 dlci 100 (0x64,0x1849, static,CISCO, status defined, active With the dynamic mapping I can't ping the other routers interface (11.0.0.1). The static map successfully pings the other node. I understand how to set up it up. What I don't understand is why the static mapping works and the dynamic mapping doesn't. Can someone please explain this?

Re: Basic Frame Relay question [7:64923]
They could. In fact, its quite likely. The link from your CPE goes into a port on one of their WAN switches. from there it goes over a trunk utilizing either Fast Packet (FP) or ATM to another WAN switch. There may be a number of WAN switches between your CPE and the destination CPE. You can get more detail from the documentation on Cisco's WAN switches.

Frame Relay Question [7:48126]
Hi, Reading a document on Frame Relay it was mentioned that : B(e)= T(c)*Access Rate And it has mentoned that access rate is the clocking rate; the maximum rate at which the data can be transfered. My question is that if the Access rate is the maximum rate,how can the B(e) be greater than the access rate.

RE: frame relay question [7:47498]
You know, this brings up a good question...My company has sites all across the country, and for every spoke site, we were able to get the exact same DLCI, and at the hubs, we were able to get a range of DLCI's in increments of 5 going out to each of the spokes. How is this possible? I completely understand that the DLCI is locally significant, and that it only defines the connection between the Frame switch and the customer CPE, but what are the odds of the exact same DLCI on so many different switches being available?

RE: frame relay question [7:47498]
Having worked building a Carrier's ATM-F/R backbone, I can tell you that the scenario you posted isn't as unique as it may seem. First of all, as you stated correctly, DLCIs are locally significant on a per INTERFACE basis. That concept applies to both, the WAN switch and the CPE. Carrier's WAN Switches typically have plenty of INTERFACES (physical ports) to provision customer PVCs on. Therefore, Carriers can provision as many DLCI=16 for instance, as F/R interfaces each WAN Switch has. At the hub location, the Carrier most likely will assign you a brand new Interface (physical port). Therefore, you the customer, have the entire range of DLCIs to request from the Carrier (16 through 1007 on Cisco WAN switches). There are WAN Switch Module DLCI limitations, depending on what type and brand of WAN switch Carries use. At each of the spoke locations, depending on the CIR your particular PVCs require, the Carrier will either provision your PVC on an existing but under-utilized Interface (meaning that you may or not get the DLCI you want, although most likely you'll get what you ask for). Or if your PVC's CIR is fat enough, it will be provisioned on a brand new Interface. Therefore, you'll get any DLCI you want or ask for, provided that the Carrier's DCLI policy allows it, and most do I believe. Now, mapping customer's F/R PVC DLCIs to ATM PVI/VCIs is a whole lot different beast on its own. But, that doen't have anything to do with assigning similar DLCIs at the spoke sites.

Re: frame relay question [7:47498]
to the frame switch, each link can have the exact same dlci. if you have fooled with using cisco routers as frame switches, you will get the idea how this is possible. the programming instruction says ( in English ) any frames using this port are dlci xx and if they are incoming, send them out that port as dlci yy essentially, a frame PCV is a series of links, each of which has a unique identifier. cust_1---dlci_16--port_1_frameswitch_port_2dlci_397---port_7_frameswitch _port_9---dlci_120cust_1 cust_2---dlci_16--port_3_frameswitch_port_4dlci_397---port_8_frameswitch _port_8---dlci_120cust_2 the only thing that has to be unique in this situation is the port on the frame switch. along each link of the pvc, the dlci is unique only to that link. If any of these links were carrying multiple PVC's then there would be multiple and unique DLCI's for each PVC on that link. so yes, from the telco standpoint, it is far easier for the switch tech to use the same methodology, and far easier for the telco to have some standard practice. my experience is the telco's really hate it when customers start asking for unique dlci numbering systems. plus it is likely that it will take longer for your link to get working right, and you will have to spend time arguing with the switch tech.

Re: frame relay question [7:47498]
good questions. in theory, you may request any dlci you wish, so long as it is in the legal range for the carrier. this would be numbers 16 through 996? for some, or through 1004? for others in fact, if you have a good rapport with your carrier, and they in turn have their act together, this is common practice. OTOH, in my experience, telcos just want to get the work done, and they will configure the dlci starting with 16 because it's easy to remember. the switch techs just bang out their configs with no conscious thought intervention. if you have nothing fancy going on ( and it appears you don't ) the only required configuration on your router is setting the frame relay encapsulation, and setting the ip address. at that point the circuit will come up. you can check this using the show frame pvc, show frame lmi and show ip interface brief commands. lmi will detect and use the single pvc with no other tweaks required. if you have multiple pvcs on a circuit, you would, of course have to use frame map commands, or use point-to-point subinterfaces in conjunction with the frame interface-dlci command. best wishes.

either way. You can provide DLCI's or you can have them assigned to you. They are locally specific. Some companies like having there own range of DLCI's for admin and management purposes.

Re: frame relay question [7:34090]
Where did you get 28MB from? In your original email you said that each location needs 14 MB. Are you taking into account that the circuit is full duplex and adding the input and output rates together? If so, that is not necessary. If you have three remote sites with 15MB fractional DS3 frame relay service (assuming you can get that from your provider) then you only need a single DS3 at your central location, again assuming that your provider offers a frame relay DS3.

ouch! we have no such restrictions here in Atlanta! :) Chuck Larrieu 02/01/02 02:34PM Some telcos have some basic oversubscription requirements, designed more so that they can sell you more bandwidth than as a real practical requirement. Here in California, for example, the local telco permits no more than a 2 for 1 oversubscription. So if you have 20 spokes, each at 256K CIR, then you MUST have a minimum 2.56 megabit CIR at your center ( fractional DS3 or ATM ), for example.

Re: frame relay question [7:34090]
14MB is the CIR and 28MB is the port speed. Normally we assume that the port speed should be double of the CIR, which might not be right. for the remote site, if CIR is 14MB(actually what we can get is 15MB), the port speed we can get from the vendor is 45MB. so every remote site needs a DS3 access circuit. the numbers here are all assumptions. but it presents a question I have. for the central site, the aggregate port speed is less than 2 DS3, but how can you assign those DLSIs to the 2 DS3 access circuits?

each remote has two DLCI's - one to the first T3, one to the second. you use load sharing to balance traffic across the links.

Hello, This might be a simple/rehashed question. I appreciate any feedback from anyone who can comment on this.. If you were to order a higher guaranteed rate /port speed on an existing frame-relay connection, for example a t1 frame-relay, will there be any configurations needed on the router or CSU ?

Re: Frame-Relay Question [7:31395]
You need to config the CSU/DSU or service-mod to utilize the correct number of channels on the port, regardless of CIR. ELMI or traffic-shaping is used to shape CIR speed. SO if you orderd a full T1, but only had a 64K circuit (I hope you are using the other channels for voice or something) you would need to configure the CSU/DSU or service-mod to use all 24 channels. -- RFC 1149 Compliant. FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
RE: Frame-Relay Question [7:31395]
Yes, On the CSU you will have to tell it how many channels it is using. If you currently have 256 kbps, the CSU will have 4 channels (4x64kbps=256kbps) assigned to the Frame Relay connection. If you wish to expand your connection to 384 kbps, you will need to assign 6 channels instead of 4. If the CSU is built into the Cisco router, you will use the command: service-module t1 timeslots 1-6 under the interface configuration to assign the first 6 channels. If the CSU is a stand-alone, you will need to read the manual to figure that out. On the Router you don't really have to do anything, unless you're using dynamic routing protocols that are utilizing the bandwidth in order to deside the route. If that's the case, you will need to change the bandwidth on the interface. The command to use on the interface is: bandwidth 384000 for 384kbps. If you have any problems, you can send me your current config, and I can tell you where to change what. Hth, Ole ~~~ Ole Drews Jensen Systems Network Manager CCNP, MCSE, MCP+I RWR Enterprises, Inc.

Ole Thanks for the info. What I was wondering is that the stated/physical speed might be let's say 128K but the guaranteed rate may be less that that. That brings me to my next question, a 128K Frame Relay mean you get Full 128K speed ? According to what I read, in frame-relay, the Telco will set your actual port speed to less that what you have ordered. They have a statement in your order sheet informing you of the guaranteed rate (which is less than what you have ordered). That is what confusing me.. --- Ole Drews Jensen wrote: Yes, On the CSU you will have to tell it how many channels it is using. If you currently have 256 kbps, the CSU will have 4 channels (4x64kbps=256kbps) assigned to the Frame Relay connection. If you wish to expand your connection to 384 kbps, you will need to assign 6 channels instead of 4. If the CSU is built into the Cisco router, you will use the command: service-module t1 timeslots 1-6 under the interface configuration to assign the first 6 channels. If the CSU is a stand-alone, you will need to read the manual to figure that out. On the Router you don't really have to do anything, unless you're using dynamic routing protocols that are utilizing the bandwidth in order to deside the route. If that's the case, you will need to change the bandwidth on the interface. The command to use on the interface is: bandwidth 384000 for 384kbps. If you have any problems, you can send me your current config, and I can tell you where to change what. Hth, Ole ~~~ Ole Drews Jensen Systems Network Manager CCNP, MCSE, MCP+I RWR Enterprises, Inc.

Because your provider has defined the PVC on their switch. Why?

Hi.. Assume that I have several routers attached to a FR Cloud and they are already communicating with each other. Now, one of you (who reads this subject) wants to build up a new connection between one of his routers and mine. Since there is a common network between us, each router attached to that cloud has to have a unique identifier. Using this identifier, anybody should be able to set-up a PVC or a SVC to another persons router (if he is granted,of course) anytime. Now , here is (are) the question(s).* I have not seen such an identifier during the configuration of FR circuits *. Don't tell me that DLCI is the identifier, because it has no global significance, but just a local parameter. In this case, how is a FR packet switched inside this common FR cloud.? Don't we have to worry about configuring PVC s, because this is (is it really) done by Telco?. If so, how do we set up SVCs then? What kind of a header does a FR packet have. How does a FR switch tell my packet from those of others.? I would very much appreciate your enlightment . Just give me a clue, no details needed. Thanks in advance.

Re: Frame Relay question. [7:26819]
The wan provider maps the DLCI to the IP of the FR switch at the opposite end through special tables.. Furthermore, the Frame Relay header is stipped off when entering the cloud and travels around via regualr IP or ATM, etc. The FR header is then put back on once it reached the opposite FR switch.

Re: Frame relay question [7:23104]
Good Explanation Paul !!! Paul Jin escreveu na mensagem news:[EMAIL PROTECTED]... 1 - FR treats p2p subinterfaces as a distinct stand alone interface, meaning the router is tricked into thinking it has multiple serial interfaces instead of just one. -- thus, the physical interface might be s0, but you might create 10 subineterfaces p2p from s0.1- s0.10. The router will think that even though all these PVCs come in through the same physical interface, it will think that the router actually has 10 serial interfaces, thus no need for split horizon. When you do multipoint or do the FR PVCs on the physical interface, the router believes that all these communication is converging back to the same physical interface. It does not think that even though, you might have 10 PVCs, all coming from 10 separate locations, that these PVCs are separate. All it sees from this point of view is 1 pipe back into itself, thus your need for split horizon or it thinks it needs to enable split horizon to stop any loops. 2 - NBMA (Non-Braodcast Multi-Access) that is what frame relay is. You can compare this to BMA and an example of that is ethernet. In ethernet, you have devices that connected to a common multiaccess device and the nodes have the ability to do a broadcast to find each other. In FR, you have multiaccess capability, such as multiple PVCs converging into 1 primary location. For example, the 10 remote sites going into 1 HQ, but FR does not give you broadcast capapbilities that is available in the ethernet network.

Re: frame relay question [7:20609]
In the frame relay cloud, under certain unusual circumstances (including a trunk line that goes unidirectional), the one or both edge frame relay switches may not see the outage. LMI will therefore not report the failure from the edge switch to the router, the PVC status is not changed on the router, and you have an interface up/up even though it doesn't work. In IOS 12.1+, you can configure frame-relay end-to-end keepalive on the routers to get around this kind of failure. This command tells both routers to force the interface down if they cannot communicate across the link, even if LMI from the switch reports the PVC is active. Without an IOS that new, you'll have to rely on your DBU log entries to document the problem. It may help if you manually try to ping across the link (i.e. use extended ping to force the pings across the frame relay subinterfaces instead of the dbu) so you can tell ATT point blank that both routers are up and working, but the PVC is not. With MCI, you can open a ticket and have it sent to their Hyperstream or Concert Frame groups and try to get a tech who understands this kind of failure (some do, many don't). At ATT, I believe the equivalent group is the backbone group, but don't quote me on that. HTH, doctorcisco Silicon ... just fancy sand. Hello, We have ATT frame line between US and Asia.

Re: Frame Relay question ? [7:20590]
Any IGP will equal cost load share, it's the switching method that's more important. You could set up a multilink group which combines the two interface to a multilink interface for example but this does not give you a 256K link, you still have 2 128K connections. It's much easiers and less overhead to simply enable CEF and choose your favorite loadsharing mechanism, per packet or per destination.

RE: frame relay question [7:20609]
A PVC going down will not necessarily drop the whole serial interface. Use the show frame pvc command to list your PVCs and their status. This command also gives the last time the status changed. I'm surprised you aren't getting messages about DLCI state changes - we do, and I don't think we've done anything in particular to enable them - what are your logging settings?

RE: frame relay question [7:20609]
How often and how long are the outages? Write down the times that this has happened and call it in and have ATT's Frame Relay group check the path of your PVC to see if there were any network related issues. Things that could have happened are, reroutes, downed trunks, etc... I believe ATT keeps 24 hours worth of logs on the stratacom network so if you see an outage, call it in as soon as possible and have them investigate. Another thing you could ask for is have them reroute your pvc to a different path if a better one is available.

Re: Frame-Relay question ?
Folks, While watching my beloved Seminoles get their butts kicked I decided to do this little prob on the rack. The key is that a frame-relay is DTE to DCE so all you need to do after correclty initiating frame-relay on the interfaces is to make sure you add the clock rate command to the serail interface that is DCE. Here are the configs: r1# interface Serial1 ip address 192.168.10.1 255.255.255.0 no ip directed-broadcast encapsulation frame-relay no keepalive frame-relay interface-dlci 101 r2# interface Serial1 ip address 192.168.10.10 255.255.255.0 no ip directed-broadcast encapsulation frame-relay no keepalive clockrate 56000 frame-relay interface-dlci 101 Worked like a charm.

Any questions on ATM I will try to answer, the technology is fairly new and hard to work with at times. But on a lighter note- I do have a lot of reference material on ATM that may help.

Hello: Excuse me if this kind of question doesn't belong here. I am in the process of preparing for CCNA and reading Wendell Odom book (BTW, any wanna be CCNA read this one regardless what others have to say). I am in WAN section right now. 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?

Lets say 7 sites total. 2 of the main sites have PVCs to every remote site... but none of the remote sites have PVCs between each other. So how can I set this up so that each remote site can communicate to each remote site and if one of the central sites goes down it can still use the other central site for connectivity??? I thought that I had to use frame-relay map ip statements to get the remote sites to be able to communicate through a central site but if that site goes down and theres another one there that can be used how does it know to communicate through the other site? Can I use multiple frame-relay map ip statements using different PVCs/DLCIs to the remote subnet? Thanks for the help... Cory R.

CCNA frame-relay question
Dear friends, could I ask a frame-relay question (CCNA question) If we need to setup a router as a frame relay switch and connect another router to it. Will the following configuration work? Why? Router A -DCE cable is connected frame-relay switching ! interface Serial0 no ip address encapsulation frame-relay IETF clockrate 200 frame-relay lmi-type cisco frame-relay intf-type dce ! interface Serial 0.1 point-to-point ip address x.x.x.2 255.255.255.0 frame-relay interface-dlci 102 RouterB -DTE cable is connected interface Serial 0/4, no ip address encapsulation frame-relay IETF frame-relay lmi-type cisco ! interface Serial0/4.1 point-to-point ip address x.x.x.1 255.255.255.0 frame-relay interface-dlci 102 thank you very much P/s: What is mean by "no ip address on interface Serial0 of router A and Router B Chee Tong == De informatie opgenomen in dit bericht kan vertrouwelijk zijn en is uitsluitend bestemd voor de geadresseerde.

Frame relay question
Usually if a router is at a customers site, it is set as a DTE, the carrier is set as a DCE (provide clock), when do you want to set the router as an NNI?

Re: Frame relay question
Here's my opinion; An NNI (Network to Network Interface ) is being used to interconnect 2 different frame-relay networks on a PVC basis. This way a dlci on one network can be pointed to a dlci on another network ( with the NNI in between the 2 telco's ). You normally thus don't need to configure it as an NNI, unless you need traffic to be transmitted from one frame provider to another...
