Layer 1 Loop test over MPLS

I was asked lately if it is possible to run a layer one loop test on a T1 through an MPLS cloud. My answer was that it does not matter. MPLS is at a different layer. I was told that this is different. When you send a loop code, when testing a T1 with ESF, it is not possible.
Here we have two sites having point to point connection (Pure layer 1 ) and going through an MPLS cloud.

Hi,
OK! I am going to try to be clear about this.
It is not really an issue. This was a discussion that took place about a two sites (A and B) that are connected in a point-to-point with a T1.
Now this connection is being moved to an MPLS cloud.
The tech was asking, in the case he wants to run a loop test at the physical layer. How should he proceed? I told him that he has now two local loops, he needs to test both separately. He replied that he wants to test all the way through the MPLS cloud to reach the remote site. He said that when sending a loop code with ESF, the PE strips the ESF part from the loop code and label only the payload (which is not clear to me).
Imagine you have a test device connected to the Demarc A and you are testing the link up to Demarc B. Can you run the loop test across the MPLS cloud?

Ask the Expert:Concepts, Configuration and Troubleshooting Layer 2 MPLS VPN – Any Transport over MPLS (AToM)

With Vignesh R. P.
Welcome to the Cisco Support Community Ask the Expert conversation.This is an opportunity to learn and ask questions about concept, configuration and troubleshooting Layer 2 MPLS VPN - Any Transport over MPLS (AToM) with Vignesh R. P.
Cisco Any Transport over MPLS (AToM) is a solution for transporting Layer 2 packets over an MPLS backbone. It enables Service Providers to supply connectivity between customer sites with existing data link layer (Layer 2) networks via a single, integrated, packet-based network infrastructure: a Cisco MPLS network. Instead of using separate networks with network management environments, service providers can deliver Layer 2 connections over an MPLS backbone. AToM provides a common framework to encapsulate and transport supported Layer 2 traffic types over an MPLS network core.
Vignesh R. P. is a customer support engineer in the Cisco High Touch Technical Support center in Bangalore, India, supporting Cisco's major service provider customers in routing and MPLS technologies. His areas of expertise include routing, switching, and MPLS. Previously at Cisco he worked as a network consulting engineer for enterprise customers. He has been in the networking industry for 8 years and holds CCIE certification in the Routing & Switching and Service Provider tracks.

Hi Tenaro,
AToM stands for Any Transport over MPLS and it is Cisco's terminology used for Layer 2 MPLS VPN or Virtual Private Wire Service. It is basically a Layer 2 Point-to-Point Service. AToM basically supports various Layer 2 protocols like Ethernet, HDLC, PPP, ATM and Frame Relay.
The customer routers interconnect with the service provider routers at Layer 2. AToM eliminates the need for the legacy network from the service provider carrying these kinds of traffic and integrates this service into the MPLS network that already transports the MPLS VPN traffic.
AToM is an open standards-based architecture that uses the label switching architecture of MPLS and can be integrated into any network that is running MPLS. The advantage to the customer is that they do not need to change anything. Their routers that are connecting to the service provider routers can still use the same Layer 2 encapsulation type as before and do not need to run an IP routing protocol to the provider edge routers as in the MPLS VPN solution.
The service provider does not need to change anything on the provider (P) routers in the core of the MPLS network. The intelligence to support AToM sits entirely on the PE routers. The core label switching routers (LSRs) only switch labeled packets, whereas the edge LSRs impose and dispose of labels on the Layer 2 frames.
Whereas pseudowire is a connection between the PE routers and emulates a wire that is carrying Layer 2 frames. Pseudowires use tunneling. The Layer 2 frames are encapsulated into a labeled (MPLS) packet. The result is that the specific Layer 2 service—its operation and characteristics—is emulated across a Packet Switched Network.
Another technology that more or less achieves the result of AToM is L2TPV3. In the case of L2TPV3 Layer 2 frames are encapsulated into an IP packet instead of a labelled MPLS packet.
Hope the above explanation helps you. Kindly revert incase of further clarification required.
Thanks & Regards,
Vignesh R P

GRE over MPLS

Hello people,
im facing problem trying to establish a GRE tunnel over mpls. The topology goes as follows:
(server) ----CE1(6500)-----PE1(6500)----vrf cloud-----CE2(6500)--FW
-server needs to establish a gre tunnel with FW.
-server receives a default route from CE1 via OSPF.
-CE1 has an default static route pointing to the next hop which is an interface VLAN (in a vrf) on PE1.
- PE1 receives a default route generated by CE2 (via mpbgp).
In this situation the GRE tunnel wouldnt come up.The only way i got the GRE to work was replacing the default static route on CE1 with a more specific static route.
On both cases (default AND specific static routes) the connectivity(ping) from end to end was there.
Has anybody seen anything alike?
thanks,
Bruno

You could be looking at some recursive routing throug the GRE interface, so the second it comes up it will try to put the GRE packets through the GRE tunnel, this creating a loop. Are you using a dynamic routing protocol to get network info over the GRE tunnel or a static route if so, how is it setup ?

How to run multiple CodedUI Ordered Tests over multiple Test Agents for parallel execution using Test Controller

we are using VS 2013, I need to run multiple Coded UI Ordered Tests in parallel on different agents.
My requirement :
Example: I have 40 Coded UI Test scripts in single solution/project. i want to run in different OS environments(example 5 OS ). I have created 5 Ordered tests with the same 40 test cases.
I have one Controller machine and 5 test agent machines. Now I want my tests to be distributed in a way that every agent gets 1 Ordered test to execute.
Machine_C = Controller (Controls Machine_1,2,3,4,5)
Machine_1 = Test Agent 1 (Should execute Ordered Test 1 (ex: OS - WIN 7) )
Machine_2 = Test Agent 2 (Should execute Ordered Test 2 (ex:
OS - WIN 8) )
Machine_3 = Test Agent 3 (Should execute Ordered Test 3
(ex: OS - WIN 2008 server) )
Machine_4 = Test Agent 4 (Should execute Ordered Test 4 (ex:
OS - WIN 2012 server) )
Machine_5 = Test Agent 5 (Should execute Ordered Test 5 (ex:
OS - WIN 2003 server) )
I have changed the “MinimumTestsPerAgent” app setting value
as '1' in controller’s configuration file (QTController.exe.config).
When I run the Ordered tests from the test explorer all Test agent running with each Ordered test and showing the status as running. but with in the 5 Test Agents only 2 Agents executing the test cases remaining all 3 agents not executing the test cases but
status showing as 'running' still for long time (exp: More then 3 hr) after that all so its not responding.
I need to know how I can configure my controller or how I can tell it to execute these tests in parallel on different test agents. This will help me reducing the script execution time.
I am not sure what steps I am missing.
It will be of great help if someone can guide me how this can be achieved.
-- > One more thing Can I Run one Coded UI Ordered Test on One Specific Test Agent?
ex: Need to run ordered Test 1 in Win 7 OS (Test Agent 1) only.
Thanks in Advance.

Hi Divakar,
Thank you for posting in MSDN forum.
As far as I know, we cannot specify coded UI ordered test run on specific test agent. And it is mainly that test controller determine which coded UI ordered test assign to which test agent.
Generally, I know that if we want to run multiple CodedUI Ordered Tests over multiple Test Agents for parallel execution using Test Controller.
We will need to change the MinimumTestsPerAgent property to 1 in the test controller configuration file (QTControllerConfig.exe.config) as you said.
And then we will need to change the bucketSize number of tests/number of machines in the test settings.
For more information about how to set this bucketSize value, please refer the following blog.
http://blogs.msdn.com/b/aseemb/archive/2010/08/11/how-to-run-automated-tests-on-different-machines-in-parallel.aspx
You can refer this Jack's suggestion to run your coded UI ordered test in lab Environment or load test.

How to stop after first loop operation over?

Hi friends.
How to stop after first loop operation over?
I have a loop operation in module pool program.
After first loop over I want to stop.
I used the STOP keyword, but it is going to dump.
Thanking you.
Regards,
Subash

Hey,
The statement STOP is forbidden in methods and, since release 6.10, leads to an uncatchable expection during the processing of screens called with CALL SCREEN...
As they said above, use a EXIT statement to fix this DUMP...

How to provied Redundancy for VRF MGMT with help of BGP over MPLS(MPBGP)

Hi,
Please find the Network Topology.
This is One Remote site and mamaged by Mgmt office.
All devices on remote site is accessed by MGMT Office. My organisation seek for Redundancy for Managing devices.
My administration is from MGW to R1. I am new to MPLS.
AS u can see in diagram, R1 have 3 VRF(Voice,Signal and MGMT).Currently i have primary link over whitch we are running MPBGP.
Traffic from these VRF goes to this primary link. Currently Secondary link is not connected.
Now my organisation proposed for the secondary link and they want that only traffic from VRF -- MGMT should go through MPLS RTR R2 (the secondary link ) , when the mgmt routes not learned from MPLS RTR R1 (Connected to the SP1 ).
Current R1 config
There is IBGP betweem R1 to both MPLS RTR.
BGP Config

so what configuration need to done at R1 to achiev the redunancy for MGMT vrf ?
if possible please reply with sample configuration.
or
IN MPBGP protocol, where i will apply routing policy to apply as- path prepand    so that Route would be secondary to neighbor.
IGP-OSPF and BGP over MPLS is running.
on Which address-familiy nbr,should i apply, is it in VPNV4 or IPV4 or IPV4 VRF ?
if i want 10.36.128.0/26 prefix should go to Neigbhor MPLS R2, what should i use access-list or Prefix list?
please provide the reply with its config .
thanks in advance,

Can I build a test over several pages, and give instant pass/fail feedback.

I want to build a test over several pages. I would like to have buttons where you click on the answer, and at the end of the test show pass/fail and answers to failed questions. I also want to show the percentage to the test answers, such as 76% out of 100%. I would like to adjust the percentages depending on the amount of answers per questions. Let's say there are 7 questions for the test, a passing score would be 71%, if there are 5 questions, a passing score would be 80% and so forth.
I am sure there are many questions regarding this, feel free to ask any and I will answer as much as possible.
I have Keynote 09, Numbers 09 and Pages 09, I would prefer to work with Keynote and hopefully use the other two as needed.

Thanks, while it worked on yours it doesn't work on mine, any other ideas?
Are you holding down the "d" key, all by itself, just after the system shuts down for a restart?
And how long did you hold it down?
I held mine down for about 40-50 seconds. Then I lookat at my routers WAN light and it was flickering so I let up on the d key.
If that does not work then maybe there is something wrong with your MBP. Is that the reason you want to run this test, something isn't right with your unit?

Point to Mulipoint L2VPN trunks over MPLS

Can we have trunk between more than 2 CE over MPLS in short we are looking for the point to multipoint MPLS L2 VPN where more than 2 CE will share the common ethernet segment over MPLS to share the vlan database
Let me give more info @ solution which we are trying find out
CE1,CE2,CE3 & CE4 are the core switches at respective location, we are looking for the same vlan database between these core switches over the MPLS
CE1 will be connected to PE1
CE2 will be connected to PE2
CE3 will be connected to PE3
CE4 will be connected to PE4
so can we have the L2 vpn between CE1,CE2,CE3 & CE4 where the interface connected to respective PE's will be TRUNK ?

hi
thanks for the pdf, I had tried the VPLS earlier. the circuit are coming up but I am not able to ping between CE's Vlan ip address although VC are up
PE end config
interface GigabitEthernet1/35
description L2 Connectivity to KBL039SW1 (TEMP)
switchport
switchport access vlan 100
switchport mode dot1q-tunnel
l2protocol-tunnel cdp
CE-1 end config
interface FastEthernet1/0/48
switchport trunk encapsulation dot1q
switchport mode trunk
end
int vlan 100
ip address 10.10.10.1 255.255.255.0
other end vlan 100 ip address is 10.10.10.2 but not able to ping this ip address from CE-1
any guess what cpuld be the problem?

FR over MPLS

Dears,
hope you support me understtanding the following:
i have the following topology:
now i need CE1 and CE2 communicate to CE3 ( CE3 connected to mpls through ethernet) over MPLS cloud and be aware that mpls cloud working perfectly but my head stund at how to make CE1 and CE2 connect to customer VRF on PE router through FR switch .
please i need your support.
thanks in advance

Check whether you have enabled IP CEF .

Layer a grid over photo

How do I layer a grid over a photo and print photo with grid...... I use this method for drawing. Thanks!

Aperture excels at converting, developing, storing, retrieving, and publishing digital photographs. It has limited tools for creating graphics from your photographs. For that you need a graphics program. Graphics program allow compositing.
Search the forum for "compositing" -- I think you'll turn up some helpful posts with links.
You could, of course, print the photograph and then draw your grid right on the print.

VoIP, Video Polycom over MPLS

Hi
Any one using Vidoe polycom and VoIP over MPLS? We have around 5 offices and they want to use Video Polycom over MPLS. If someone can provide Pro and Con for that and any document or link much appreciate it. Thanks in advance.
Sai

i havnt done polycom over mpls
but i would like to give u hints to consider it
the first think u need to know from the ISP what COS they put in as priorty and how many COS they provide u based on SLA and how match max traffic then they start to drop traffic
the other think is to know how the polycom mark the traffic and u need to calssifiy it and put it in proper calss based on the classes provided by the mpls ISP
good luck
and hope this helpful

Cell-relay over MPLS using MGX 8850

we have existing ATM network using TDM links between MGX 8850 & have PVCs for voice & data traffic. We are planning to migrate the same over MPLS network
following is the setup.
MGX1----> PE1 ------>MPLS Cloud ------> PE2 ---->MGX2
As per this plan we will terminate existing TDM trunks to PE routers at both the end & map VPI/VCI values at PE routers for virtual ATM pvcs over MPLS cloud.We are using cell-relay over MPLS with VC mode. My query is, can we enable MPLS L3 & L2 on the same last mile in this scenario? We want to have one IP over ATM interface on same ATM interface at PE router & make that part of VRF & enable L3 MPLS VPN between all the sites for any to any data transfer. For data we don't want to use L2 MPLS as its any to any & it will end up with too many ATM PVCs.
In this setup PE router & MGX will be configured in NNI-NNI at both end. If we want to create one sub-interface at same ATM interface at PE router end, then that port need to be in UNI. Is it possible to use same ATM trunk port as NNI & UNI?
In MGX 8850 we have RPM,AXSM & VISM modules.

the following document should give you some idea,

Secondary Site SRST over MPLS

My company has IPT in our HQ. We have a secondary mfg location in the next town that is connected via a point-2-point T1, and we run VoIP over it. We have a PRI for PSTN access at the HQ. The 2nd location had POTS access until someone canceled them feeling they were unnecessary (pros and cons for that) At both locations we have SRST on a 1760-V.
Our location in CA (HQ is in WI) currently has its own PBX which is dying. I wish to roll out VoIP to it over MPLS, which I would then replace the P2P T1 and put it in the MPLS cloud too. I plan NOT to add a voice gateway at the CA location and just put a switch out there and route all calls through WI (Leaving a POTS line for fax and 911).
Management only worry is if the phones go out at the HQ, CA will be stranded. I said SRST would kick in and maintain call processing, until the batteries ran out. Only THEN everything would be down. (The other scenario would be the HQ building is compromised somehow).
Is it possible if a DR plan is in place that if an extended power loss occurs, or the HQ building is destroyed, that call routing could be established through our secondary location; since everything is connected via MPLS? I know POTS lines would need to be reestablished, but could the second WI location run SRST for the CA site?

I am not asking how to do it, just if it is possible down the road some time. This could sell the plan to management if it is possible.
