Re: Frame-Relay question ?
Mindiani, In this configuration, there is no switch sending LMI to the routers. The router declares the line protocol down after three missed keepalive intervals (10 seconds each, by default). One way to fix this problem in back-to-back frame relay configs is to add "no keepalive" under the serial interface config. This assumes you have Router1 as the DCE end of the cable.

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.

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...

Will each facility be pumping a solid 14mb across the wan all day long?
If so, one ds3 (45mb) will suffice at the HQthen purchase shaped DS3

site would be 84mb. should I order 2 T3 access circuits or 3 at the central
site? if 2, how can i config the 3 DLCI across the 2 T3 circuits? because
there would be 1 DLCI needed to be split between the 2 T3 circuits.
thanks again!

Re: frame relay question [7:34090]
Is ATM a consideration? I believe you can get up to OC12 speeds with ATM,
and you can use FRATM ( frame to ATM ) to connect your remotes. Assuming
your telco can support you there, you would have the best of both worlds, so
to speak.

Re: frame relay question [7:34090]
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.
I believe the reasoning is that the telco does not want a lot of calls
complaining about their circuits when the problem is overutilization of
bandwidth. And they want to sell you more, of course. ;->

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.

I have seen circuits built and have been working absolutely perfectly with
5:1 contention. For this scenario I would easily suggest a 2 or 3:1
contention. Lets face it what are the chances of the three buildings
loading 14 MB each at the same time??? I say nil

RE: frame relay question [7:34090]
In order to accomodate your needs you could
have each remote site have a pvc built over
each of the T3s. This removes the need or
worry over the physical circuit.
How about using a carrier that can do frame relay
at the ends and IP or ATM in the middle??
At the remote ends how do you plan to get that
much traffic out? The best bet would be a T3
at the remote sites too.

well, if you really need 90mb, then the best thing to do would be to inverse
mux on your end and have the telco muc them on yoru end... (2 ds3's)
then you would have a 90mb frame pipe to bring remote site into.

of course it's fine to oversubscribe like that ( except maybe in a busy VoIP

but that doesn't help the telco bottom line ;->

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?

Re: frame relay question [7:34090]
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.
OR
a couple of folks have suggested muxing multiple T3's at your host site. In
the environment you describe, you should have no problem getting your telco
to work with you. doing so would eliminate the need for two pvc's from each
remote.

Another important factor is where the sites are located. congestion is most
prevelant in the

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.

Hi Matt, You are correct...The DLCI is being learned from the frame-relay switch...You don't have it configured so it will show up under the unused column when the sho fram pvc command. Did you order the pvc and haven't configured it or assigned it to an interface/sub-interface? Or the provider assigned it to a wrong dlci which I just had happened last week and the week before.

Re: Frame Relay Question [7:31210]
Yes it definately could have been learned from the provider or you had it configured on your router at some point and later took it out of your config. It the second case is true a reload will get rid of it. Does it claim to be learned dynamically??

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.

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.

RE: Frame-Relay Question [7:31395]
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.

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.

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 ? [7:20590]
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 [7:20609]
The reason that both serial interfaces stay up is because the routers are talking LMI their repective switches no problemo. On a link between the US and Asia thaere are most likely other switches and network devices so if you did a sh frame pvc you would see your PVC is either inactive or deleted.

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 AT&T frame line between US and Asia.

Re: frame relay question [7:20609]
I would think that LMI is disabled and no keepalive is set on the point-to-point interfaces therefore even though PVC is down . Interface still show up up . My advice is that you should always turn on LMI unless it is a simplex link for the case of a satellite receive-only downlink regards, suaveguru --- MADMAN wrote: > The reason that both serial interfaces stay up is > because the routers > are talking LMI their repective switches no > problemo.
