Frame Relay and as5350

Dear Experts,
we got a 2811 framrelay hub ,which also runs VOFR ,since the device is not fully compatible with our PBX we decided to replace it with an As5350 ,but unfortunatley the as5350 does not support VOFR , is there any way to configure Vofr on as5350 with ios upgrade or any other way?
if not , is it possible to configure a 3640 router as the hub router wich runs VOFR ,and also configure the 3640 as a gatekeeper to route the calls to as5350 for termination and vice versa ?
all suggestions are welcomed,
Farshid.sh

Hi, as you noted the 5350 doesn't support VoFR. You can only terminate VoFR on other models, having the 3640 doing GK would not help, because GK is for VoIP only.
Hope this helps, please rate post if it does!

Frame Relay and MPLS

Hi,
I want to ask about the frame relay and MPLS.
Frame Relay Scenerio
The frames reached at the frame relay network and forwarded on the basis of DLCI. All the VCs are defined prior to the traffic on the network on the basis of DLCI (This is just like the MPLS network as packets are forwarded on the basis of Labels).
Now my Question is How can MPLS is used in frame relay network or what are its affects in the presence of DLCI (As DLCIs are also performing the same task and also works on layer 2) or these two are different equivalent technologies ?

Hi Muhammad,
The answer is : MPLS is working on FR like it's working on ethernet. Because the FR and Ethernet are running on Layer2. It's told that MPLS is working at layer 2.5 , meaning that is between Layer 3 , and Layer 2. So in order to work it needs a layer2 forwarding in your case FR's DLCI. On top of the Layer 2 it is the MPLS header.

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

Ipx over frame relay and route redistribution

Hi,
When I configure ipx over frame-relay multipoint interface, I need to run eigrp and disable the split horizon, and I'm running ipx rip on the same router thus, redistribution is automatic by default. This will cause potential routing loop when the route is advertised back from the same interface. In this situation, I have few questions:
1. How to prevent routing loop in this situation?
2. What is the administrative distance for ipx rip, eigrp, nslp?
3. How does eigrp and rip convert the metric?
Thank you

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 !!

What is the access rate of the head end?
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.

ADSL over Frame Relay

Hi all,
I have a Ascend DSLTNT in my Lab and they only support ADSL over frame relay and I dont have compatible modems. Is there any cisco ADSL WIC card which I can use in 2600 router for adsl or sdsl over frame relay. I will be grateful for your help.
Thanks in advance.

Configuring CE-PE link on Frame Relay over ATM

Hi!
Need you guys expert opinion on how to configure configuring CE-PE link on Frame Relay over ATM. I am stump by this one because I never done it before. The CE is a Cisco 7206 with ATM PA and the parameters given to us is DLCI number in x/y format...isn't that the format for PVC. When asked, my SP contact says that it is indeed FR over ATM. Any of you guys who have experience to guide on this or point me in the right direction is most welcome. Thanks
Rgds
Helme

Hello Helme,
ask your provider if they are doing FR to ATM service interworking.
In that case one side is configured for Frame-Relay and the other side for ATM
Service interworking is done by provider.
Verify that you have the same MTU on both sides and configure following ISP specifications
ATM uses two numbers to identify a PVC
int atm 4/0
no ip address
no shut
int atm 4/0.1 point-to-point
mtu 1500
ip address x.x.x.1 255.255.255.252
pvc x/y
enc aal5snap
protocol ip x.x.x.2 broadcast
this should be enough to have it working
on the other side configure or have a point-to-point subif configured on FR
see this example

Accessing Oracle through Frame relay

Is anyone using a 56k Frame relay communications connection to the applications. We are attempting to deploy sales offices on Frame relay and are experiencing very slow response time. THe interesting thing is that the communications provider is telling us that we are not using all of the available bandwidth!!
Other ideas or experiences would be great. You can also contact me on my e-mail at [email protected]
Thanks for any input

Hi,
I'm using 128k frame relay + satelite and I was fancing this situations, so the network admin find out that the link was losting packs.
Ask your communications provider to check it. I think it�s possible do it using ping.
Besides that we are using metaframe to improve the performance because we have a lot of conetions.
Good look.

Fram Relay hub and spoke scenario

See the attachment please
Requirements:
1.Using only physical interfaces configure a Frame Relay hub-and-spoke network between RTA and RTB and RTC, RTB as the hub.
2.Traffic from RTA destined for RTC should transit RTB, and vice versa.
3.Use only the DLCIs specified in the diagram.
4.Do not use any Dynamic layer 3 to layer 2 mappings over these frame Relay connections.
5.Do not send any redundant broadcast traffic from the spokes to the hub.
RTB (Hub):
interface Serial0/0
ip address 3.1.1.2 255.255.255.0
encapsulation frame-relay
frame-relay map ip 3.1.1.1 200 broadcast
frame-relay map ip 3.1.1.3 300 broadcast
no frame-relay inverse-arp
RTA (Spoke):
interface Serial0/0
ip address 3.1.1.1 255.255.255.0
encapsulation frame-relay
frame-relay map ip 3.1.1.2 22 broadcast
frame-relay map ip 3.1.1.3 22
no frame-relay inverse-arp
RTC (Spoke):
interface Serial1/0
ip address 3.1.1.3 255.255.255.0
encapsulation frame-relay
frame-relay map ip 3.1.1.2 33 broadcast
frame-relay map ip 3.1.1.1 33
no frame-relay inverse-arp
My queries:
A- Does he use these two statements because (frame-relay map ip 3.1.1.3 22 and frame-relay map ip 3.1.1.1 33 ) of requirement number 2 ?
B- Doesnt he use keyword broadcast in these two statements (frame-relay map ip 3.1.1.3 22 and frame-relay map ip 3.1.1.1 33) because of requirement 5?
C- Does that mean if requirement 5 is not there we should have used broadcast keyword ?
D- Does not that contradict with what Cisco syas: The broadcast keyword is commonly used with the frame relay map command ?
E- By using these two statements (frame-relay map ip 3.1.1.3 22 and frame-relay map ip 3.1.1.1 33) doesnt my network become full mesh? but if you look to the diagram it is partial mesh ?

Answers to your queries:
A. Correct
B. Correct
C. That depends. In most cases, it is a good idea to have broadcasts on, especially when using routing protocols like OSPF which send traffic to multicast destinations. I would habe it on most times.
D. The recommendation from Cisco is not contradictory. The lab scenario is making you do something quite specific so you have to follow that. You don't always have to follow requirements in order to make things work.
E. No. Full-mesh refers to a full mesh of PVCs. If there was a PVC from A to C it would be full mesh.
Hope that helps - pls rate the post if it does.

Do you think isdn and frame-relay expire?

in new ccnp book i didnt see any thing about isdn and some object
even in ccna exam i didnt see any question about isdn and if i remember about frame-relay
what's your opinion?do you think isdn and frame-relay expire?is there any place for this technology on it nowadays?
thanks

Hi Reza,
if you are talking about new CCNP curriculum, then ISDN and Frame relay technologies are no longer included there. ISDN and Frame relay were included in the Remote access paper of CCNP old curriculum but now that paper is replaced by Secure Converged Wide Area Networks paper which includes MPLS, IPSec VPNs and other technologies.
But as Rick said in earlier post that ISDN and frame relay are still very much in use.
hope it helps ... rate if it does ....

ISDN and FRAME-RELAY

Hi All,
I currently have two 2500 routers, to get my hands dirty on ISDN and FRAME-RELAY experiments do i need seperate routers for them?. Because i cannot see where to connect to in regards to the required connections i.e.
2 x Asynchronous/Synchronous Serial Interfaces (DB60)
4 x Serial Interfaces (DB60)
1 x ISDN Interface (RJ45)
1 x Token Ring interface (DB9 and RJ45)
THat i normally hear about when refering to ISDN or FRAME RELAY.
Somebody please put me through.
Secondly i would like to connect my 2500 to the internet ...please put me through how.
Many thanks in Advance

Olu
There are some challenges in what you want to do with this equipment. If each router has 1 x ISDN interface then you can use that for ISDN - but you will need some other piece of equipment to furnish the ISDN switch functionality. You can not just connect 2 ISDN interfaces back to back.
You would be able to do some testing of Frame Relay if you connected the routers back to back - if one of the cables is a DCE cable and one cable is a DTE cable. The testing that you can do with 2 routers back to back is somewhat limited. You could do much better testing if you had a third router which could be configured as a frame relay switch.
Connecting your routers to the Internet will be possible if you connect one of the serial interfaces to an Internet Service provider.
The routers have token ring LAN interfaces. Unless you have some token ring MAUs to establish the connections you will not be able to do effective testing using the token ring LAN interfaces.

Connection from remote sites (Frame Relay WAN) to AS/400 dissapears

Hello,
We have the following problem appearing in our environment:
All connections from remote sites dissapears unexpected from AS/400. After 2-3 minutes remote users get normal connectivity again.
The environment is the the following:
Frame Relay/ATM WAN (Frame Relay on remote sites and ATM in datacenter) comes to Cisco 7204VXR router which connected to LAN switch with 10/100/1000 ports. AS/400 with Fast Ethernet interface also connected to the similar LAN switch. CEF is enabled on the router, IOS version 12.4.3a. We have ETHSTD *ALL parameter set on AS/400. Remote users uses TCP/IP and Telnet but there are a number of 5494 controllers wich uses SNA.
We got the problem for the first time after we enabled CEF on the router.
I suspect that the cause of problem is Ethernet frames of different standards due to ETHSTD *ALL, but can neither reproduce the problem nor understand why it behaves so.
Have anybody had similar problem?
I would be very thanksfull if somebody can help me to solve it.
Thank you in advance.
//Mikhail Galiulin

Hi Martin,
Cisco 7200 itself can access AS/400 as well as all other hosts in the same with AS/400 LAN. There is no any outage in communications which goes to another LAN segment via Netscreen firewall while the communication via Cisco is down. Only those hosts which connected via Cisco are experiencing the problem. I can not say where the traceroute from AS/400 stucks (there are other people who maintain the machine and they never could catch the exact moment of outage).
To turn off CEF I treat as the last option actually and unfortunatelly there is no guarantee that software upgrade will help (we have 12.4.3a now).
So first of all I'm trying to understan WHY it happens because I can not see any systematics in the problem appearance. It can happen 3 times under 2 days and then dissapear for 1-2 months...

2621 as a Frame Relay switch & terminal server?

Is it unwise to use a 2621 as a combined Frame Relay switch & terminal server in a home lab? Both functions seem to move a general-purpose router into the dedicated use category.
Likewise, is it true than configuring a router to serve as a Frame Relay switch isn't memory intensive?
If I am wrong in my assumptions, please feel free to correct my misperceptions.
Thanks.

Using the 2621 for frame and TS should be fine. I do it in my lab and have never had a problem.

When 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.
