Frame Relay Configuration
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?
version 12.1

ip http server

Sorry when I transposed the ip's to post i made a mistake in them. 1.1.1.2 is my address and 1.1.1.1 is the gateway for them (their side of the t1). I have it configure correctly on my router with the real ip's.

Hi
I am trying to understand the build we have on our CE routers from the Service Provider. Frame-relay encapsulation is build on the Wan interface with LMI configured/dlci enabled on sub-interface. At the PE end, there is also Frame-relay configuration on the PE end...How does that work? Does Cisco have any docs that I could read?Hello Mary,
on the PE router there is a Frame-relay interface and sub-interfaces.
the PE-CE link is the VRF access link what is different on the PE side is the presence of the command ip vrf forwarding VRF-name in the correct FR subif.
Then the MPLS cloud includes the backbone links of the PE routers.
see the following link for an introduction to MPLS VPN

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

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
HelmeHello 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
http://www.cisco.com/en/US/tech/tk39/tk53/technologies_configuration_example09186a00801747e3.shtml

Can't ping routers across point-to-point frame-relay

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 -
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 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.

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)

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.

service-module t1 timeslots 1-24Hello,
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
bandwidth 2048
ip address XXXX
ip nat outside
frame-relay interface-dlci 555
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.
Regards,
Brajesh. -
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
c2600, c3600, mc3810, c7200, c1750
all running the right level of IOS.
12.1(5)T and above should work well. -
Why is everything on my Frame-relay network working fine with different encapsulation types ?
I have a cisco frame-relay switch with the encapsulation type on IETF.
I have a cisco router with
the encapsulation type on cisco.
Still everything works fine.
How come when it is a different dlsi byte structure ?
Is it because also my switch is a cisco and it uses cisco encap afterall ?A cisco router will understand both the IETF and normal Cisco encapsulation when receiving data regardless of configuration. However, depending on the configuration, it will only send one type.

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
interface Serial0.1 point-to-point
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! -
"frame-relay fragment XYZ" causes link to stop working
Hi people!
I have a strange problem regarding the "frame-relay fragment xyz" command. I have the following configuration:
interface Serial0/0
description R3926704: phy. FrameRelay-Interface (Se0/0)
bandwidth 512
no ip address
max-reserved-bandwidth 95
encapsulation frame-relay IETF

ip address A.A.A.A B.B.B.B
frame-relay class egress_queue_512k

frame-relay cir 486000
frame-relay bc 48600
frame-relay be 0
frame-relay mincir 486000
service-policy output egress_queue
... if i change the map-class to:
map-class frame-relay egress_queue_512k_voice
frame-relay cir 486000
frame-relay bc 4860
frame-relay be 0
frame-relay mincir 486000
service-policy output egress_queue
frame-relay fragment 53
... no traffic goes over the link any more. no telnet no other traffic. the strange thing is, that i can ping the router!??
does anyone know what's the problem here??
thanks for any help!!
Marioalso, this fragment size must be set on both sides of the link, the same size, even if the hub has a greater link speed than the spoke.
