Try setting encapsulation to "frame-relay ietf" and LMI type to "ansi" or
"ansi annex d"

Re: Frame Relay problem

[jason yee]

You might want to check the LMI type follow by the
encapsulation type to see if it is ok 


also set keepalive to zero to see if the interface
comes up if not you got a back interface

RE: Frame Relay problem

[Winchester, Derek S.]

Well it's not mentioned if this is a current connection or a new install. If
this is a current connections and looking at the counters it looks like you
cleared it you might not want to change the lmi type. If this is a new
connection then I would try the auto detect feature or find out the correct
lmi

RE: Frame Relay problem

[Guyler, Rik [EESUS]]

Title: RE: Frame Relay problem





Hmm...well, you don't give us a config or show version so we don't know for sure what the LMI settings are or what the IOS version is.  However, by the show interface you provided, it looks as if LMI is to blame.

Newer IOS autosenses the LMI type, but still, I don't trust it.  If you have an older IOS or you have a newer IOS that is "autosensing", I would hard code the LMI type.  Also, since IOS sets the LMI type to Cisco by default, when/if you hard code it, you might try setting to use ANSI LMI.

Good luck!

RE: Frame Relay problem

[Winchester, Derek S.]

Looks like you are not receiving any LMI. The problem is either with your CO
or your CSU. Check you physical connections and then call the CO to see if
they can tell you if they are having any problems

RE: Frame Relay problem

[Stull, Cory]

timing or incorrect lmi type..  If its a newer ios with autosensing lmi then
it is probably a timing or circuit issue...  Is it a T1 and did you set your
timeslots?

Subject: Frame Relay problem


Hi colleagues,

I have a problem with my frame relay connection; the serial interface is 
up/down, and when I debug the serial interface, I can see that the interface

is constantly trying to restart:23w5d:

Serial5/0: attempting to restart:

--More--

What could be the reason for this ? I'll add the output for the sh int:

Re: frame-relay lmi question...

[Kristopher B. Climie]

Yes, that is correct.  IOS 11.2 and later will autosense the LMI type.  It
is possible that the LMI cannot be decoded, and in that event, you may have
to manually set the type.   (i.e. frame-relay lmi-type ansi )

RE: frame-relay lmi question...

[Johns, Andrew M ETC (CNE N654)]

I found in my CCNA notes that the LMI-type only needs to be specified for
IOS ver 11.1 and earlier, 11.2 and up its autosensed. It says if using 11.1
or earlier, specify the type used by the switch (telco). It should not
matter at all whats on the other end, its is only concerned with the local
connection between the local router and the local telco switch. Does that
sound right?

There are a few objectives dealing with OSPF and 
EIGRP in NBMA domains, so from that standpoint there is some configuration 
knowledge involved. It doesn't deal specifically with FR, but you should be 
aware of the implications and Cisco's recommendations in dealing with 
it.

You only need the basics. BSCN assumes that you have as a prerequisite at
least ICND or ICRC. There is no advanced Frame Relay in either of those, and
having taught BSCN last week, I can vouch for that course, too.

Re: FRAME RELAY PROBLEM

[William Swedberg]

It is my understanding that on point-to-point
interfaces they need to be on seperate subnets.  If
you have multiple routers coming into one interface,
declare the interface a point-to-multipoint interface.
 Do this when you create the subinterface or use the
"ip ospf network X" interface command.  

See this URL for Design suggestions.

Dear Cisco Guys,

Ping from router A to Router B : OK 
ping from router B to router A : OK

PC get the dynamic IP from DHCP sever located on HQ.
Let say tha PC A have IP : 10.10.1.10/16
Routers A and B are Cisco 2501.

The problem: 
Can not ping from PC A to router B and also from router B to PC A.

Do we need assign a gateway in the PC, i think not because Br and HQ is in
one network.

Is there any wrong configuration in a routers?
Attached is router configuration.

RE: Frame-relay multipoint configuration & DLCIs

[Ruslan S Tchinyakov]

Really bu default both interface and subunterface are multipoint-
so don'be confused with number of DLCIs-
just remember about reachabelity issues- you'd have
SINGLE LIS (logical ip subnet)- so if you use classless aproach or VLSM-
think on yor routing protocol carefully- put attention on split-horizon and
summarization issues!
 Then remember on maps- thay need to establish full mesh
if you have a lot of money to buy VCs and want everything works ok.
So let's read Caslows famous book- one chapter is completely dedicated to
your question-
"To map or not to map".

Subject: Frame-relay multipoint configuration & DLCIs


Guys,

This time I have a question regarding mulipoint FR configuration.
Her is the concern:
int s 0/0.1
ip address 1.1.1.1 255.0.0.0
frame-relay map ip 2.2.2.2 200 broadcast
frame-relay map ip 3.3.3.3 300 broadcast

Is this configuration means that there are two PVCs from this source to two
destinations(2.2.2.2 & 3.3.3.3)?. How come a single interface (s0/0.1) can
have two DLCIs (200 & 300)?

Or should I configure it this way

int s 0/0.1
ip address 1.1.1.1 255.0.0.0
frame-relay map ip 2.2.2.2 200 broadcast
int s 0/0.2
ip address 1.1.1.2 255.0.0.0
frame-relay map ip 3.3.3.3 300 broadcast

I am trying to understand the benefit of the multipoint configuration.
Could someone clairfy this

Thanks
I need to finish FR to start ISDN !

RE: Frame-relay traffic shaping question

[Ruslan S Tchinyakov]

In VoIPoFR (not good implementation- but in my
situation VoFR was much worse)- we tried both,
but finally used FRTS- we needed FRF.12 fragmentation and
some other things. But you should evaluate at your own-
weght all pros and contras- values and restrictions (RSVP, queuenig, your VC
structure and so on).

Re: Frame-relay traffic shaping question

[Michael Fountain]

I'm not very familiar with generic traffic shaping.

But, at first glance it looks like it is basically the same thing as frame 
relay traffic shaping except that it does not dynamically change based on 
network congestion because there is no method set up to notify the router of 
any congestion encountered.

Using 'frame-relay traffic-shaping' indicates that the router can change the 
traffic rate based on becns or foresight notifications of congestion.  You 
will have to use a 'frame-relay map-class' to tell the router how you want 
to shape the traffic.

With generic traffic shaping you can specify the rate directly on the 
interface because you do not need to tell it what sort of congestion 
notification to listen to.

When you use the command 'frame-relay traffic-rate 64000 128000' (for 
example) you get the following values -
mincir - 32000- This is amount sent when congested
CIR - 64000   - This is the amount to send with no congestion
bc - 64000- This is the amound to send per interval
be - 64000- This is the burst amount to send in the first
interval
tc - 125  - This is the interval time in milliseconds


The router will send out traffic in the following pattern each second (for 
tc=125 or 1/8 or a second) when there is no congestion

  bc+be / bc / bc / bc / bc / bc / bc / bc

so for this config it would send -

  128000 / 0 / 0 / 0 / 0 / 0 / 0 / 0

then it would repeat that for the next second.

By doing it like this the router attempts to send the full amount of traffic 
every second.


You can go in and specify the Bc, Be, CIR, and mincir to be other values to 
try and shape the traffic in different ways, but there is rarely any need 
to.

For example, if you were to use the following config
map-class frame-relay test
  frame-relay cir 128000
  frame-relay mincir 64000
  frame-relay bc 8000
  frame-relay be 64000

you would get the following traffic pattern -
  72000 / 8000 / 8000 / 8000 / 8000 / 8000 / 8000 / 8000

So, you would still get 128K in the one second.

  The problem with this is that the router can only bust beyond Bc (up to 
Be) when it has excess bandwidth available.  So, if it keeps sending at 8000 
then it will be at 64000 each second after that.  Until it has transmitted a 
second with less then 64000.  Lets say in one interval it only transmitts 
6000.  So, next interval it was an excess of 2000 that it can transmit as 
Be.  This can continue until it was built up 64000 which is the max Be it 
can ever have.

Its sorta like roll-over minutes for cellular phones :)

By using the the 'frame-relay traffic-rate xxx yyy' command you are fooling 
the router into sending max Be every second.  It thinks its Bc is 64000 so 
the in the intervals it cant send traffic (because it hit line speed in the 
first interval) it builds up credit again so it can burst at full Be on the 
next seconds interval.

It really depends on how you want your traffic shaped and what sort of 
applications are running over the link.  But, if they aren't extremely time 
sensitive, the generic command should work.

The one thing to watch for in the 'frame-relay traffic-rate xxx yyy' command 
is that it assumes your mincir is 1/2 your average speed value.  So, if you 
set your average to your contracted CIR and the router encounters 
congestion, it will slow down to the mincir which is half of that.  To get 
around this you can set your average speed to double your CIR.

If you order your CIR at 1/2 your line speed (128K port, 64K CIR) you can 
use something like this 'frame-relay traffic-shaping 128000 128000'
The router will run at 128000 unless it hits congestion and then it will run 
at 64000.

Hope that helps.
Mike

A point to point interface can have only one PVC.  A multipoint can have
multiple PVC's.  With multiple PVC's on an interface, you don't have to do
DLCI mapping, because inverse arp will take care of it.  Once
subinterfaces are involved, as above, then you must do the maps you did.
Frame-Relay is a multiple-access wan technology, so having multiple PVC's
on an interface is valid.

In my opinion you want the second way.  You see, the reason you would put
all PVC's under one interface, a multipoint interface, is mainly because
your building a mesh or a semi-mesh, and you are using a single network.

You are using two different Class A networks, and so two PtP interfaces
are the way to go IMHO.  Also be aware that the two ends of the
links.whether it be a PtP or a multi-access link, should be in the
same subnet, and in neither of your examples is this the case.

Re: Frame-relay traffic shaping question

[John lay]

As far as I know, they are both equal. So you can do it by either way.
Please someone correct.

Re: Frame-relay traffic shaping question

[Kent]

Wizards,

As the FRTS has been brought up here, I really want to
take this chances to get some help from you in
understanding this. 

When we enable the 'frame-relay traffice shaping'
under the inferface, we start using frame-relay
traffice shaping not generic shaping, right?

in the map-class of frame relay, we can configure CIR,
Bc and Be, how is this different from just configure
'traffic-rate xx yy' in the map-class?

As far as I understand, it is not quite effective to
controll QoS in FR, I am not sure whether someones
have seen some detailed perfermence comparation betwee
two kinds of traffic shaping.

Thanks

Re: Frame-relay traffic shaping question

[Alexandre Eduardo Garcia]

Has anyone used Generic Traffic Shaping for Frame-Relay?

The GTS permits the use of Weigh Fair Queue (the FRTS doesn't).

I would like to know if GTS works as good as FRTS.

Re: Frame-relay traffic shaping question

[Michael Fountain]

The easiest way to do this is to only configure the CIR and Line speeds and 
let the rest default.

Example commands -

int s0
frame-relay traffic shapping Enable FRTS on the interface
frame-relay class ExampleClass   Shape as defined in map class

frame-relay map-class ExampleClass
frame-relay traffic-rate XXX YYY   ### XXX = CIR, YYY = Max Speed
traffic-rate adaptive-shaping becn  Use BECNs (not foresight)
 for for thottling


  If you set XXX to 512K and YYY to port speed, he will transmit at port 
speed unless he receives BECNs from the network, and then he will throttle 
down to 512K.
  If you set both XXX and YYY to 512K he will always transmit at 512K

  Depending on your service provider and how congested their network is you 
may be able to go in and buy a small CIR like 64K and then ignore that and 
have your router set to send at 512K.  If you do that and some time in 
future your SP starts dropping packets (because they are over CIR) you will 
have to go to them and buy up your contracted CIR, but until then you can 
save some money.  We've been running AT&T Frame Relay for a couple of years 
and have yet to receive a single BECN.

  It is possible to go in and specify mincir, Bc, Be, etc.  But unless you 
are going VOFR or some other application that has specific needs using 
generic FRTS will cover just about everything.

  Hope that helps,
Mike

Re: Frame Relay and DE bit

[jenny . mcleod]

(OK, let's see if this one gets through to the list...)
Asynchronous CIRs are offered by some carriers but not all of them.  It just
means that you can get two different CIRs on the same PVC - one upstream, one
downstream (however you want to define upstream and downstream :-)
So if you have a lot of traffic going from your central site to remote sites
(interactive, software downloads, whatever), but not much going the other way,
it may be more economical to have say a 256Kbps CIR from the central site out to
a remote site, but only 128Kbps from the remote site to the central site (using
the same PVC).

Re: Frame Relay Switching

[Darren Ward]

If you want DLCI 16 on one interface to switch to DLCI 16 on the other AND
DLCI 18 on one interface to switch to DLCI 18 on the other then the config
below will do it for you.

Darren

!
frame-relay switching
!
interface serial 0
 encapsulation frame-relay
 frame-relay intf-type dce
 clock rate ?
 frame-relay route 16 interface serial 1 16
 frame-relay route 18 interface serial 1 18
!
interface serial 1
 encapsulation frame-relay
 frame-relay intf-type dce
 clock rate ?
 frame-relay route 16 interface serial 0 16
 frame-relay route 18 interface serial 0 18
!



So effectively you have two PVC's on each

Do one thing .. post your setup requirements and the equipment details ( if
thats not a prob ) and then i am sure someone ( ho0pefully me :) ) will be
able to help you better ...

One thing i want to make clear is that you cannot route a single DLCI to
multiple DLCIs.

RE: frame-relay design

[Taylor, Don]

You only need one PVC per remote in a hub & spoke environment, which in your
example would be a total of two PVCs for the whole network. Even if you were
to design a full mesh it would only take 3 PVCs to connect each site to the
other two. R1-R2-R3-R1 (I suck at ASCII art).

Think about it, if you have two PVCs on the same physical interface, going
to the same location, what have you accomplished except to include more
overhead? The second PVC can't be used for redundancy or load balancing if
it's on the same physical circuit.

Does that help?

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

RE: frame-relay CRC

[Taylor, Don]

This is usually a circuit problem somewhere along the path, but I've also
seen where a bad switch port will cause problems. If the circuit tests fine
with all patterns over an hour's time, I'd ask the carrier to try swapping
ports to see if things change.

RE: Frame Relay switch

[Cate, Constance]

The "DCE" that is referenced in setting up a router to use as a frame relay
switch is different than the physical layer DCE reference that requires that
a clock rate be defined.

Taking into account that the router you have does meet all the requirements
for a FR switch all that is really needed is the command;

Frame_switch(config)#frame-relay switching

since your frame switch is normally considered the DCE you'll also want to
enable you clock rate on the connecting serial interfaces. As well you could
use the following  interface commands.

Frame_switch(config-if)#encapsulation frame-relay
Frame_switch(config-if)#clock rate 64000
Frame_switch(config-if)#frame-relay intf-type dce

these are some of you basic commands for the frame switch.

Re: Frame relay question

[Barry Hofland]

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...

Re: Frame Relay Interworking with ATM

[peter whittle]

Kamoto

There are normally 2 basic methods of interworking ATM with Frame Relay
which are normally handled by a FRATM.

They are: Network Interworking Function (NIWF)
Service Interworking Function (SIWF)


NIWFs work in pairs, have both a Frame i/f and an ATM cell based i/f.
Basically they carry the Frame Relay frame less flags and fcs.  As far as
the Frame Relay nodes are concerned, you are effectively using the ATM
cloud as a virtual piece of wire. You can carry many dlcs in a single
virtual channel.

You only need 1 SIWF, again it has both a Frame i/f and a cell i/f.It
takes the payload out of Frame Relay and repackages it into ATM.  You
require a separate virtual channel for each dlc.

Both normally use aal5 encapsulation.


Hope this helps

Peter

Here's how our company does our WAN:

We have a "primary" site and a "backup" site.  Our branches
each have two PVCs--one to each of the sites.  This provides
redundancy should either the primary or backup site have an 
issue.  It also would save the day if there was a problem 
along the way within the Frame Relay network which only affected
one of the PVCs.

Of course, this doesn't help if the physical circuit goes down
or if the Frame switch the branch office was going to was experience
issues, so we have BRIs configured to do dial backup as well.

Since the applications we use are all client-server, the branches
have no need to communicate directly with one another. We have
approximately 70 branch offices, and this approach works quite well
and for a decent cost.

RE: Frame Relay and DE bit

[jenny . mcleod]

I agree with everything that Chuck says except the very first sentence.  The DE
packets tell you very little about your CURRENT reliability, but they do give an
indication of potential future problems.
Simple (and fairly simplistic) example.  Let's say this link is provided by a
new carrier, or a carrier that has recently installed frame relay in this area
(dunno about in the US, but there's lots of places in Australia that don't have
many frame relay customers :-).  You're the first customer on this part of the
network.
They provide you with say 256K access, and say 64K CIR (figures out of the air).
Nobody else is using the infrastructure, so you can happily send traffic at 256K
for long periods of time without any congestion - there's nobody else around to
congest the network.  'You beauty', you think - why bother paying for higher
CIRs?
Time goes by, as time is inclined to do, and the carrier gets more customers.
They might upgrade their network, but they'll almost certainly oversubscribe -
if you're only paying for 64K CIR, why should they provision their network to
give you 256K all the time?
Funny, you seem to be getting more FECNs and BECNs and dropped packets.  Your
traffic hasn't changed, so why the drop in performance?  You get what you pay
for.

That level of FECNs and BECNs indicates that you're not having problems yet
(although it would be worth checking the FECN/BECN levels at the other end of
the link).  But keep a close eye on it.  The DE packets show that you're getting
more than you're paying for (which is A Good Thing, if you ask me), but that
could change due to things completely outside your control.

Also, as an aside, I have heard that some carriers don't bother setting the
FECN/BECN bits.  That's probably not the case here as there are some BECNs
showing, but if it was, then you could be getting severe congestion without it
showing up very easily - except of course in your user response times...

Re: frame-relay design

[jenny . mcleod]

Well actually, if you really mean hub and spoke, you will NOT have 99 PVCs per
site.  Or two per site in the original example.You'll have 99 PVCs
connecting to the hub site, and one at each spoke site.
You seem to be confusing hub and spoke with full mesh, where every site is
directly connected to every other site.  For N sites, a full mesh network will
indeed have N-1 PVCs attached to each site (a total of (N-1)*N/2 in the whole
network).  Generally, full mesh networks are regarded as being, shall we say, a
bit over the top for anything other than very small numbers of sites.
A hub and spoke design has a single hub site and multiple spoke sites, with a
single PVC from the hub to each spoke, and no PVCs directly between the spoke
sites.  If there's N sites (including the hub), then there's a total of N-1 PVCs
in the whole network. Other options are partial mesh (take a full mesh and
remove links that don't get significant traffic, thus reducing the number of
links and therefore cost and management effort), or distributed hub and spoke
(not sure if that's the correct term but it describes it well - main hub has
PVCs to secondary hubs, which have PVCs to spoke sites).  Or combinations of the
above.
If you're doing a hub and spoke design, you can get around the single point of
failure issue by having a multi-homed hub and spoke design - have two hubs and
each spoke has PVCs to each hub.  Doubles the number of PVCs, but some carriers
offer 'backup PVCs' at a lower cost - they only kick in if the main PVC fails.
Or you can back up your frame network with ISDN or some other on-demand service.

RE: Frame Relay and DE bit

[Sereno, Patrick]

Title: RE: Frame Relay and DE bit





Larry,


The DE bit specifies that the Frame Relay network may discard this frame if it encounters congestion between the ingress and egress.  Generally speaking, the DE 'should' be set by your ingress router for all frames transmitted that exceed your CIR during the sample period (1 second).

The 'out bytes' counter is only related to the other 'out *' counters. In this case, you're transmitting no DE frames.  This tells me that 1) your router is not setting the DE bit on frames that exceed CIR, or 2) your traffic is not exceeding the outbound CIR.  If 2, then you've got low utilization or your CIR matches your physical bandwidth.  As for case 1, you must configure the router to set DE when exceeding CIR.  I believe this is a new feature, IOS 12 or 11.3.  However, I've never configured it.  Additionally, I don't think most Frame providers pay attention to it (I may be mistaken).

Re: frame-relay design

[Phil Barker]

Assuming one Hub and 99 spokes you would need 99
"frame-relay interface-dlci" statements per site if
you wanted to talk to every remote site.
I cannot see this being a practicle solution
though, i.e You would be committing a massive 'single
point of failure at the Hub', plus I very much doubt
that all the sites would want direct access to each
other anyway.

Re: Frame Relay and DE bit

Larry,
 I'm a newbie on FR, however, I would compare your
in PACKETS with your in DE PACKETS and you are losing
2/3rds of your data. I would look at increasing your
CIR by 2/3rds as a result. Unless of course nobody is
complaining about the access speed ?

You can configure a FR switch by using the following set of commands
..for example .a cisco router acting as a FR_Switch have its S0 and 
S1 configured as,

interface Serial0
no ip address
encapsulation frame-relay
no ip mroute-cache
clockrate 64000
frame-relay interface-dlci 20
frame-relay lmi-type ansi
frame-relay intf-type dce
frame-relay route 40 interface Serial1 20
!
interface Serial1
no ip address
encapsulation frame-relay
clockrate 64000
frame-relay interface-dlci 40
frame-relay lmi-type ansi
frame-relay intf-type dce
frame-relay route 20 interface Serial0 40

Re: Frame Relay switch

[Atif Awan]

1) Auto-sensing is a feature of the router IOS. IOS versios 11.2 and later
support LMI auto sensing.

2) Yeah 100 and 200 are the DLCIs and this command establishes a PVC.

Re: Frame Relay switch

[M Z]

Thanks Atef and Nigel for your responses,
the two other questions I have are
1)how do you make the switch auto-sense the LMI type, or is that a function 
of the router?
2)in the command frame-relay route 100 interface serial 2 200
are the 100 , 200 refer to the DLCI's and that is the command I need to map 
a PVC between DLCI 100 and DLCI 200.

Thanks so much.

Re: Frame Relay switch

[Nigel Taylor]

Taking into account that the router you have does meet all the requirements
for a FR switch all that is really needed is the command;

Frame_switch(config)#frame-relay switching

since your frame switch is normally considered the DCE you'll also want to
enable you clock rate on the connecting serial interfaces. As well you could
use the following  interface commands.

Frame_switch(config-if)#encapsulation frame-relay
Frame_switch(config-if)#clock rate 64000
Frame_switch(config-if)#frame-relay intf-type dce

these are some of you basic commands for the frame switch.

Re: frame-relay CRC

[Doug Laing]

CRC errors are  physical layer errors.  First thing to do is to have the line
checked.  (I have experienced many times where I had to prove to the service
provider that the error was on their side and not on our client's equipment.
Even though they claimed that the line tested fine).

RE: Frame Relay limitations question

[David Smith]

We actually are using a 3640 with a T1 controller.  We currently have about
30 sub-interfaces and everything seems to be working fine.  I am trying to
find the limitations of my routers.  Even if we get multiple T1 controllers,
if there is a limit of 60 DLCIs (or 80, or whatever) per router, that is
something I need to know about for my spending projections.

The problem I am trying to solve is "To add another 100 to 200 remote
offices to our FR WAN, what additional hardware will need to be purchased?"
It makes sense to me to learn the limitations of the routers (memory, CPU,
interface speed), and see how things can be done as cheaply as possible.
>From there, more money can be spent to solve issues or limit risk as
necessary.  There is no problem that more money cannot be thrown at, but for
the money to be effective in this case I have to know the inherent
limitations of the router.

Why would the 2500 die with 60 sub-int into one interface?  What would cause
it to die?  Is the limitation the shared memory space?  How can I get better
planning numbers?

Thanks,
Dave

Dave,

To quote HCB yet again "WPAYTTS?" (What problem are you trying to solve?)

This should be considered in context - don't ever think about running 60
sub-int into a 2500, it would just die before your eyes.  If you work for
that large a company that you need 1000s of DLCIs to converge on one
location, do you really want them to all to terminate on one port, on one
router, on one single point of failure?  If you are serious about
resilience, which I assume you are (I hope at least), then spread stuff
around a little.  2500s are Access routers - ie one per remote site with
maybe a couple of PVCs at most.  At a pinch I would terminate maybe half a
dozen PVCs on one at a concentrator site, but I would much prefer a couple
of 2600s, or a 3600, or bigger kit as the situation dictates.

bear in mind what you are paying for the circuits - WAN bandwidth ain't
cheap (if it is for you and you're in the UK then mail me back now!).  It's
worth balancing the cost of your circuits, router hardware, and the cost of
downtime to arrive at a suitable compromise.

RE: Frame Relay limitations question

[Michael Fountain]

Well, to give a little more info on what the article below said,

If they are Point-to-Point, you have to create a sub-interface for each PVC, 
so you are limited to the number of IDBs you can have in a router.  I think 
the numbers in that article might be a bit low, but it might be correct for 
most models.  Our Cisco rep recently told us that a 7200VXR routers were 
limited to 3,000 IDBs, although I think the VXR chassis is one of those geek 
things it was talking about :)

If they are Multipoint PVCs, the numbers below look pretty good to me, but a 
bit conservative for a max value.  We have a bunch of Cisco 4700s with 16M 
DRAM, and each of them has 4 T1s on them with 200 PVCs per T1, for a total 
of about 800 per router.

Hope that helps.

RE: Frame Relay limitations question

[David Wolsefer]

Here is an excerpt from my frame relay paper on CerticationZone.com which
explains this:

Historically, IOS has had a limit of 300 interfaces per router chassis,
including both hardware and software-defined interfaces and subinterfaces.
Some recent IOS versions may raise this to 700-1000 on specific platforms.
This limit, which is based on the number of internal Interface Data Blocks
(IDB), may not be reachable due to memory restrictions on certain routers.
For example, a Cisco 2500 keeps its interface buffers in shared I/O memory.

Hi all,

I am doing some projections for growth in our companies FR cloud.  I was
checking the limitations of routers when I came across this article.  The
link is below.

http://www.cisco.com/warp/public/125/26.html

The following is directly from the article.  The last part is what I have a
question about.  Does anybody know where the limitations per router platform
come from?  The article seems to be missing some information about why the
2500 can only support 60 DLCIs, the 4000 can support 120, etc.
  
Thanks in advance,
Dave

DLCI Limitations
Subinterfaces count toward the practical upper limit of 230 Interface
Descriptor Blocks (IDBs). In other words, Cisco IOS currently doesn't
support more then 230 interfaces on the router (real or virtual) unless you
have an ISP Geeks Image which has 1024 IDBs. How many DLCIs can one
configure per physical interface? How many DLCIs can one configure in a
specific router? These two questions are frequently asked. Disappointingly,
the answer is, "it depends." 
DLCI address space: Approximately 1000 DLCIs can be configured on a single
physical link, given a 10-bit address. Because certain DLCIs are reserved
(vendor-implementation-dependent), the maximum is about 1000. The range for
"cisco" LMI is 16-1007. The stated range for ANSI/ITU is 16-992. These are
the DLCIs carrying user-data. 
LMI status update: The LMI protocol requires that all permanent virtual
circuit (PVC) status reports fit into a single packet and generally limits
the number of DLCIs to less than 800, depending on the maximum transmission
unit (MTU) size. 
MTU= 4000 bytes   Max DLCIs app= (MTU bytes - 20 bytes)/ (5 bytes/DLCI) 
(4000-20)/5 = 796
Default MTU on serial interfaces is 1500 bytes, yielding a maximum of 296
DLCIs per interface. Please note that these numbers vary slightly, depending
on the LMI type. The maximum DLCIs per router (not interface) platform
guideline, based on extrapolation from empirical data established on a Cisco
7000 router platform, are listed below: 
*   Cisco 2500: 1 X T1/E1 link @ 60 DLCIs per interface = 60 total 
*   Cisco 4000: 1 X T1/E1 link @ 120 DLCIs per interface = 120 total 
*   Cisco 4500: 3 X T1/E1 links @ 120 DLCIs per interface = 360 total 
*   Cisco 4700: 4 X T1/E1 links @ 120 DLCIs per interface = 480 total 
*   Cisco 7000: 4 X T1/E1/T3/E3 links @ 120 DLCIs per interface = 480
total 
*   Cisco 7200: 5 X T1/E1/T3/E3 links @ 120 DLCIs per interface = 600
total 
*   Cisco 7500: 6 X T1/E1/T3/E3 links @ 120 DLCIs per interface = 720
total 
Note: These numbers are guidelines only, and assume that all traffic is
fast-switched.

Re: Frame Relay on back-to-back routers (without FR switches)

[K Sacca]

Remember, frame relay is an Interface Specification
only.  Frame Relay specifies how a user device such
as a router delivers info to a WAN for transmission.

So he could set encapsulation frame-relay on each
router, but what good that would do I don't know.

You can test F/R back to back as a PVC but I would
do it right and set one up with frame-relay switching

You need a FR switch in between them, most Cisco routers can be config'ed to
act as FR switches. Search the list, there are many posts on how to do this.

Re: frame relay newbie question

[Kevin S. Mahler]

Yes it is common to run IP and IPX on the same
frame relay subinterface.  The real advantage to using
subinterfaces on frame is to fix some headaches with
routing protocols in a NBMA network.

As for IPX being an issue much longer... That depends on
your customers.  Even Novell has indicated that IPX is
going the way of Disco.

Re: NetWare 5.0 was RE: frame relay newbie question

[Darren Ward]

Hmmm, we've deployed Netware 5 with NDS in a pure IP environment across
a WAN and seen significant traffic reductions using periodic NDS
replication over the old IPX and bindary environment they used to have.

It was not completely painless though as new servers had to be built in
a Lab environment to act as masters for each site, run through rigorous
compatability testing then deployed onsite and tested yet again over a
weekend.

Then it was an easy matter to migrate the legacy servers one-by-one to
the new true IP environment.

It depends on the existing environment and whether you are free to
implement a proper NDS IP networking model.
The co-existance method using IPX-over-IP Tunnels inside the servers is
a bad idea, use tunnels on the routers with IPX EIGRP or NLSP as the WAN
protocol to cut down on RIP and SAP traffic levels.

In most cases SAP filters should be applied anyway to stop those chatty
printers and so on.
Even think of using static SAP entries if you can get away with it
combined with filters.

Re: frame relay newbie question

[Darren Ward]

Netware 5 can however use IPX and sadly there are some applications that can
only use IPX/SPX still so I don't think we'll see IPX dissappear for quite some
time if ever.

Netware 5 now has a true IP stack and that is the default method of networking
in a new environment but full support for IPX is still built in.

NetWare 5.0 was RE: frame relay newbie question

[Prather, Aaron]

Title: NetWare 5.0 was RE: frame relay newbie question





Yes, you are correct.  I am working on a large project for a county school system and they are currently upgrading all of their servers to NetWare 5.0  The funny part is that at first we were using IP/IPX in compatibility mode and then were going to phase out the IPX.  But it was so slow that it was impossible to administer with all of the SAP's and what not still crossing the WAN.  They ended up upgrading the WAN and not using compatibility mode and just using all of the SAP's for communication.  I'm not sure if after all of the boxes are upgraded to 5 if they will still use IPX or migrate to IP.  Novell has a ways to go in the IP world.  So, yes, still expect IPX/SPX to be out there for a while.

I wouldn't look to see IPX/SPX dissappearing anytime soon, It'll take a
lot
of time and money for a company or organization to convert their IPX
network
to IP, for example.  (If I remember correctly Netware 5.0 and beyond
uses
and will USE IP from now on, phasing IPX out, am I correct?)

subinterfaces is that you can run IP on one and IPX on

What do you consider "much"? I would say, in general, YES.
Do you think that SNA will be an issue much longer?

YES!!! you can run as many protocols as you would like over one F/R PVC as
long as you have enough bandwidth so as to not have delay issues. You can
also prioritize the more urgent traffic.

hope this helps.

RE: Frame relay back to back

[Dollard Morgan]

the Serial 0/0 notation, as well as any 2/0 0/2 notations liek this, are
only availabe on modular equipments, wether router or switch. the first
number is the module, and the second number is the interface itself. for
example, in a 4500. If u had a quad serial interface in the second slot, and
u were trying to configure the third interface, 
the notation would look like this, int serial 1/3 , because the first int is
always 0, and the first slot as well. 
hope this helps. 
btw, in a catalyst, the first number is the number on the slot in which the
module is inserted.

Re: Frame relay back to back

[Dale Holmes]

Just use s0 Billy, you'll be fine. The s0/0 notation refers to the slot/port 
of the serial interface. This has to do with different hardware than you are 
using. As you get your hands on more and more different router models, you 
will find one with a hardware configuration that requires you to use the 
s0/0 notation...

I hope this helps!

Re: Frame relay back to back

[pedro quezada]

You you not have to map in a back to back scenarion .
inverse arp should be able to do find it's way  to the other int..This is
point to point.

My scenario is more comple than this one and i am able to ping without
mapping.i am using a cisco router with four interfaces as a cloud . one
would need mapping in a hub and spoke scenario.

Re: Frame relay back to back

[mikey]

In order to do frame-relay with a back-to-back cable, one router must be
configured as a switch - frame-relay switching (global-config) and the
interface on the switch must be configured as a logical dce - frame-relay
interf-type dce (int-config).  When I have done it, i also had to map to my
local interface with frame-relay map in order to ping the local interface.

[Brian Lodwick]

Vic,

up with 2 CSU/DSUs? or are you doing the DTE-DCE thing?

Re: Frame Relay Problem

[Miguel Harris]

First what routing protocol are you using and email me for Dynamic Routing on IP, 
OSPF, Static, IPX (Dynamic or Static), Dynamic Over Multi.

another thing check your DLCI information each router requires a DLCI for every frame 
relay virtual Circuit

This post may show my ignorance, but I'll try.  When I set up frame relay in
my lab, I used three routers.  One was configured as a frame relay switch.
I connected the other two to it and set up a frame relay connection between
them.  I was unaware that two adjacent routers could run frame relay to each
other.

I've set up a frame relay switch at home trying to complete one of the
"CCIE Lab all in one" Labs. For my question, what could cause a PVC to be
inactive? Things I've checked.

Serial is up line protocol is up on both sides.
LMI type is the same
Clocking is set on DCE side.
Encapsulation is Frame relay

What else is there to check? All suggestions appreciated.

Have you configure the frame-relay route ??? and "frame-relay 
intf-type dce" on the frame-relay switch ???
