Frame Relay point to point
Hi All,
I have configured below point to point link with FR switch in GNS 3.
below is the configuration for the senario.
R1#sh run int serial 0/0
Building configuration...
Current configuration : 144 bytes
interface Serial0/0
no ip address
encapsulation frame-relay
clock rate 2000000
no frame-relay inverse-arp
frame-relay lmi-type ansi
end
R1#sh run int serial 0/0.101
Building configuration...
Current configuration : 118 bytes
interface Serial0/0.101 point-to-point
ip address 10.1.1.1 255.255.255.252
frame-relay interface-dlci 101
end
==============================
R2#sh run int serial 0/0
Building configuration...
Current configuration : 144 bytes
interface Serial0/0
no ip address
encapsulation frame-relay
clock rate 2000000
no frame-relay inverse-arp

end
R2#sh run int serial 0/0.201
Building configuration...
Current configuration : 118 bytes
interface Serial0/0.201 point-to-point
ip address 10.1.1.2 255.255.255.252
frame-relay interface-dlci 201
end
======================
FR switch is port 1-101 for R1 serial 0/0 & Port 2-201 for R2 serial 0/0
Below is the status for the sh frame-relay map
R1#sh frame-relay map
Serial0/0.101 (up): point-to-point dlci, dlci 101(0x65,0x1850), broadcast status defined, active
R2#sh frame-relay map
Serial0/0.201 (down): point-to-point dlci, dlci 201(0xC9,0x3090), broadcast status deleted
Serial0/1.201 (administratively down): point-to-point dlci, dlci 201(0xC9,0x3090), broadcast status deleted
Please let me know where i am making a mistake.
Hello
You mentioned a FR switch, if so these routers interfaces should not be clocking - as they should be both DTE's
Delete the config (sub interfaces and default the serial interfaces ,also shut/no shut them and re apply the config)

Can't ping routers across point-to-point frame-relay
'evening,
Really basic setup. Designed with Packet Tracer, trying to ping routers across a point-to-point frame-relay. I've designed this according to three different training sources who all say the same thing. Yet, all pings failed.

ThanksTurns out the mistake was not adding a mask to the subnet. Ex:
Router_2(config_router)# network 192.168.0.0 0.0.255.255
Router_2(config_router)# network 172.27.0.0 0.0.255.255
Doing that on both routers made the hosts capable of pinging each other.
Thanks for the tips everyone -

Benifits of point to point over multipoint on frame relay
Can anyone tell me what the above is ?
This is a big area of discussion and difficult to summarise. There are pro's and con's for configuring frame-relay on p2p, p2m and on the physical interface. It really depends on your design requirements. P2P as the name suggests just has 2 devices connected while P2M can be hub and spoke or full/partial mesh. routing protocols work in different ways depending on how the frame-relay is configured (see ospf network types and eigrp/rip split horizon). The choice of frame-relay interface also has implication on how multicast will work.
So to summarise, if you have many frame PVC's in a hub and spoke topology and use P2P you will end up with lots of subinterface which may be undesirable. P2M can get around this issue as the spoke will only need one interface, but there are other issues to think about if you use P2M. -
Frame included before In point...
Sorry for posting a second time - I realized my first post sounded a little convoluted, and am hoping to be clearer this time.
I created an In & Out point for a clip that I wanted to use. I put it in my Timeline, it was fine. After burning to a Qtime file, I noticed that the frame before my In point (which I did not want) was indeed included, but, this did not show up in my Timeline. It was exactly how I wanted it to be, in my Timeline. Then, I created a Final Cut Pro Movie file, and the frame did not show up there, but it did show up when I imported it into DVDSP. How can this be, since this was not included in my In Point to begin with, and did not show up in my Timeline? Thanks again...This is VERY BASIC video stuff. Most standard def video is interlaced. Each frame consists of 2 interlaced fields.
Try parking on a frame with a lot of movement in the canvas and set the size to 100%. You should see some vibration as each of the fields is displayed. If you're only looking at one field in the canvas (which is what happens when your canvas is NOT set to 100%) you may not be seeing a field from the previous or subsequent shot. -
Configuring Frame-Relay and the Frame-Relay Switch To Participate in WAN Routing
Hey,
My WAN in my voice lab is currently functional between all of my routers HQ, BR1, and BR1 with full-mesh connectivity. I am using my PSTN router for the frame-relay switching as is shown in the attached configs. I have used the connect commands for the PVC routing logic.
connect HQ-BR1 Serial0/3/0 101 Serial0/2/0 201
connect HQ-BR2 Serial0/3/0 102 Serial0/2/1 301
connect BR1-BR2 Serial0/2/0 202 Serial0/2/1 302
My question concerns the possibility of getting the PSTN router to participate in the WAN and the OSPF routing process? The connect command tells how the PVCs are to be connected and pass through the PSTN router. Is there anyway to do it so that a PVC connects to the PSTN router itself?
I would specifically like to create a connection between the HQ and PSTN router over the WAN. If anyone has any insight on this I would really appreciate it.
Thank you.Hello Adam,
you don't need to do FR switching.
You just need to configure a back to back PVC associated to a p2p subinterface under PSTN router interface se0/3/0 and HQ:se0/1/0. the new PVC can be 103 on both sides
PSTN
interface ser0/3/0.103 point-to-point
ip address 10.1.13.1 255.255.255.0
frame-relay interface-dlci 103
HQ
interface ser0/1/0.103 point-to-point
ip address 10.1.13.1 255.255.255.0
frame-relay interface-dlci 103
note: I was able to do this using the older syntax frame-relay route under interface configuration on frame relay switch. I would expect to work for you too with newer syntax connect.
Hope to help

When show int s0/0 I see that:16 input errors, 9 CRC. I think errors from service provider? because I alway use under 100 kps but still have some errors.
Thanks very much,
NhuongPhamWhen you're able, schedule some downtime for this circuit, and have your provide do some loopback testing on an off-hours time. Simply open a trouble ticket with them, indicating that you're taking CRC errors at the customer-premisis-equipment. 16 input hours per day doesn't seem like alot, but it's still worth checking out, especially since your WAN provider should do this for free.

ASR1K 5xE1 MFR Frame relay traffic not forwarding in one direction
Dear Techies,
Hope all is well !
Im doing this inter-op testing with Alcatel device for frame-relay and MFRs and got stuck at this situation which is actually mind boggling and I think i might be missing something "silly" :-(
Its a simple setup of
1. My ASR 1002-X with a LAN (Gig0/0/0) port is connected to a traffic generator.(ixia).
2. ASR WAN port is a 5xE1 bundled into a MFR circuit.
3. WAN link goes to a Alcatel box giving me my FR-DCE with E1s over MFR.
Issue is , I can send traffic to max throughput with flow initiated from LAN to WAN bit NOT the reverse flow initiated from WAN side to LAN port. I see traffic coming into my 5xE1s (1.8 mbps each) but the traffic just wont go to the LAN side , somewhere it gets "stuck" or "dropped".
PING works fine from both sides.......but sending traffic is not possible !!

Are you using a codec other than G711?
How many total sites are involved, what protocols are you running?
From the math, 32K is not enough CIR to ensure 4 calls proper Bandwidth. At what point is the voice degrading, is is choppy missing message, sound, jitter, echo or after 1, 2 or 3 calls.
Even if you are using G729a, voice packets could be dropped. Not to say that it is here, but look at the FRS stats to see ip packets are being dropped.
Traffic shaping is always recommended, rtp header compression will help, but the trade-off is around a 20% CPU hit.
If you implement traffic shapping , it needs to be done throughout the network as queueing delays related to data on other slow links and at the headend (specifically here) could be the cause of the distortion alone. I would at least try traffic shapping first, then if the problem doen't go away, increase CIR for Voice, if there are still issues, implement LLQ. -
All,
Sorry for asking this, but I have been beating my head against the wall here. I am getting a T1 installed in my residence for internet connectivity. I am using an old wic-1-dsu-t1-v1 in a 2610 router. I am unable to get this configuration working. I have a very simple configuration so far on the router, but I am unable to get this to come up. I have put the show run below. Some of the commands are default and are not showing up. Obviously I have changed the ip's to generic ones below. Any ideas?

Will QOS will work in this way where class is put on WAN interface where it should be service policy.
router#sh run interface Se0/0/0.1
Building configuration...
Current configuration : 239 bytes
interface Serial0/0/0.1 point-to-point

class COS-OUT-S0/0/0.1
end
COS-OUT-S0/0/0.1 is defined as policy map with class of voice and video.
When checking on WAN int #sh policy-map interface Se0/0/0.1 , can see output of service policy input/output with policy map recpective classes and packets match entries.Is QOS working with this configuration?
Appreciate any input on this.

Brajesh. -
THERE IS A FR NETWORK HUB AND SPOKE
IN STAR TOPOLOGY. AT HUB ROUTER THERE ARE POINT-TO-POINT SUBINTERFACES TO SPOKE ROUTERS AND STATIC FR MAP ENTRIES ARE PRESENT. tHE SPOKE ROUTERS COMMUNICATE WITH HUB ROUTER BUT DO NOT COMMUNICATE WITH EACH OTHER.
MY QUESTION IS WHAT TO DO FOR COMMUNICATIONS BETWEEN SPOKE ROUTERS,
1. IS ANY MORE DLCI MAY BE REQUIRED BETWEEN SPOKE ROUTERS?.
2.IS MAP STATEMENT REQUIRED, DLCI WITH IP ADDRESS BETWEEN SPOKE ROUTERS ?Abdul
There are a couple of things in your question that I hope you can clarify and if so we should be able to get good answers to your question.
At one point you describe the topology as hub and spoke and at another point you describe it as star. Most of us understand these to be two different topologies. So is it hub and spoke or is it star?
Many of us understand hub and spoke to be remote routers connected directly to a central (hub) router while a star is remote routers where some of the remote routers have direct connections to other remotes.
Also you say that the hub has point to point subinterfaces and this is generally the best practice for Frame Relay. Then you say that static FR map entries are present. I do not understand this because with p-t-p subinterfaces you do not need FR maps.
Based on what we have so far I would say that these are the answers to your questions:
1. you might choose to add additional DLCIs but they are not required. any spoke should be able to communicate with any spoke by going to the hub and having the hub forward to the other spoke.
2. No map statements should be required. Part of having p-t-p subinterfaces at the hub is that each spoke is an separate subnet. Therefore from any spoke to any other spoke is just going to a different subnet (through the hub) and no map would be required.
If these answers do not satisfy your requirements then perhaps you can clarify the points about your question.

Justify Security on a point to point circuit
Hello Everyone,
on a point to point curcuit from the Telco is there justification for putting in a firewall and IDS/IPS? Telco is saying "No" but I'm not so sure. Opinions?
All replies rated! Thanks in advance!Well, first of all I'm assuming that the curcuit is to support a connection to another network in your administrative domain (i.e. another one of your companies offices).
It depends on your requirements(including those that come from regulations/expectations/auditors/etc). What kind of traffic will go over the circuit(i.e. how sensitive is it)? Is is already encrypted (depending on where this happens, it can make IDS/IPS superfluous)? I'm not aware of any regulations that specifically require a firewall and/or IDS/IPS or even encryption of sensitive data on "private" networks like frame-relay and point-to-point.
However, if you're in the Pharmaceutical business and you have trade secrets you want to protect, you'd probably at least encrypt (ipsec, whatever) and maybe use IDS/IPS and a firewall. A bank might do the same. If you're selling toys and use the link to upload inventory, then you might not.
IMHO, you should assume that your service provider CAN and regularly DOES see your traffic. That's a problem best solved by encryption, not firewall/IDS/IPS. -
In order to provide voice quality for VoIP, is FR fragmentation equivalent to lowering the MTU size for the serial subinterface of a Frame relay subinterface?
Is there any isues like stop communications, using Low MTU ?If the router belongs to any of the
platform listed below, then use
FRF12 for you fragmentation. The MTU size
lowering also works but this can cause a high over
head as it can't be specified on a per dlci level.
With multiple dlci i.e. subinterfaces use per dlci fragmentation.. this helps reduce the overhead of changing the MTU size of the physical interface.

This should help if your router is

all running the right level of IOS.
12.1(5)T and above should work well. -
Service-policy output statement interface vs interface .500 point-to-point
We are running AutoQoS but have recently migrated our WAN service that puts our IP connectivity to a sub-interface (interface serial0/1:0.500 point-to-point and a frame-relay interface-DLCI). In our prior WAN configuration we bound the IP address directly to the interface s0/1:0.
After the migration, the auto qos statement service-policy output AutQoS is still on the interface serial 0/1:0 . Should this service-policy statement be moved down to the serial 0/1:0.500 point-to-point in order to be effective? We have been experiencing QoS problems but I understand it could be many different places, but I wanted to start here.
Thanks
ryanas a rule those are applied in a frame relay policy map.

Create the Frame Relay Policy map (and refer to the LLC policy map in the Frame Relay Config)

Hi,
Customer of me has several sites connected with leased lines. The leased lines have frame-relay encapsulation (frame-relay back-to-back)
The line has two pvc's configured, one for voice and one for data. The voice PVC works fine. On the data pvc we want to put some QoS.
Here is the partial configuration:
interface Serial0
bandwidth 2000
no ip address
encapsulation frame-relay
no ip route-cache cef
ip route-cache flow
no ip mroute-cache
frame-relay intf-type dce

ip address 10.xx.xx.1 255.255.255.252
no ip mroute-cache
frame-relay interface-dlci 120
interface Serial0.2 point-to-point
ip address 10.0.0.1 255.255.255.252
no ip mroute-cache
frame-relay interface-dlci 100
class VOICE
vofr cisco
map-class frame-relay VOICE
frame-relay cir 512000
frame-relay voice bandwidth 256000
frame-relay fragment 320
frame-relay fair-queue
Question is can I just apply a service policy out to the data DLCI or doi i also have to enable frame-relay traffic shaping?
Thanks,
JHThe disadvantage of shaping is that it will actually limit you bandwidth. That is, you won't be able to use the circuit at full capacity, because of the artificial limitation induced by shaping. This is particularly true for a situation like you where the actual circuits is a leased line, and not a FR network.
A better approach would be to reconfigure for simple hdlc encap, and run VoIP instead. This way, you would have all the QOS features you need for voice and data, and be able to use the full capacity with a much simpler configuration.
Actually, even if you want to retain the FR encapsulation and the voice over FR approach, still using a single PVC would be better, for the same reasons given above.
Hope this helps, please rate post if it does!
