How to prevent packet forwarding over non-MPLS connection.

I'm wondering if it is possible to configure Cisco ESR to not forward packet over non-MPLS connection(VPI/VCI=0/32) when an LSP for its destination has not been established, while allowing control packets(BGP, LDP, OSPF) to be sent over non-MPLS connection. The reason why I ask about is as follows.
Referring to the following network configuration,
R1 --- Cisco_ESR --- ATM_LSR --- LER --- R2
<--> non-MPLS connection
----------------------->
LSPs
----------------------->
In the ordinary operation, when a packet arrives at Cisco_LER from R1, it gets forwarded over an LSP if available, while getting forwarded over non-MPLS connection(VPI/VCI=0/32) if the corresponding LSP is not available. In the configuration mentioned above,ATM_LSR does software-based packet processing for incoming packet through non-MPLS channel, while doing cell-switching for LSP traffic. Thus if ESR sends packet over non-MPLS connection, e.g, STM-1c, the ATM_LSR could get crashed or time-critical control traffic could be delayed or lost, thereby resulting in BGP/LDP session failure between ESR and ATM_LSR or LER.
In summary, my question is how to prevent Cisco_ESR from forwarding packets over non-MPLS connection when LSPs for their destinations are not available due to LSP failures.
Thanks.

Control Packets over non-MPLS connection

Is it possible to configure Cisco router 7204 to send BGP packets not over LSP that has been established for the BGP peer, PE router, but over non-MPLS connection, while all data traffic to the PE router get forwarded through the LSP. In other words, I'm wondering it is possible to constrain all control
packets, including BGP, OSPF and LDP, to the non-MPLS interfaces, even though the LSP exists for the destination prefixes for the BGP packets.
I hope it could be applied to establishing MP-iBGP sessions between PE routers in MPLS/VPN network, in other words, we want all BGP packets not be forwarded through the LSP established between two PE routers, which is actually an ATM LER system since we have established non-MPLS connections between LERs in order to forward control packets including routing protocol and MPLS signaling protocol.
Any response will greatly appreciated.
Regards,
Yongjun.

Yongjun,
r1------r2-----r3
\-------r4----/
r1, r3 are PEs
r2 is a P rotuer
r4 is a non-LSR
r1-r2-r3 is LSP
r1-r4-r3 is a ip path, non-lsp
Then, you can do 'local-policy routing on r1 and r3 to send the Bgp control traffic over r1--r4--r3 path.
config on r1:
ip local policy route-map foo
route-map foo perm 10
match ip addr 100
set ip next-hop
access-list 100 perm tcp host eq 179 host
access-list 100 perm tcp host host eq 179
you got to do similar config on r3.
let me know if you have further q's.

MPLS over non-MPLS network

A Chairde,
I am nearly sure the answer is no, but will ask anyway.
I want to connect two private networks over a corporate WAN , and am looking to keep the router traffic (BGP) and routing traffic under control.
I only have control of the two lab routers, the routers in middle are controlled by IT dept. , is there anyway of setting up MPLS with this scenario ???
Any other suggestions ......

You could indeed run MPLS over a GRE interface.
If you want to run MPLS VPN, then I would suggest configuring MPLS VPN over l2tpv3. See the following URL for more details:
http://www.cisco.com/en/US/products/sw/iosswrel/ps1829/products_feature_guide09186a00802b4817.html
Let me know if I answered your question,

How good does Indesign work over a VPN connection?

We are a small, widely distributed publisher using Adobe Indesign, Incopy etc. We would like to allow access to our server for outside designers, and are looking into a VPN solution. We have implemented a test of VPN, and it appears to work OK for file access, however the load and save times are rather long.
Is anyone using these tools with file access over VPN in a production environment? Please let me know issues, such as reliability, file corruption or other issues. Also, what sort of non-standard configurations do you recommend for the software.
Thanks in advance for discussing this type of environment, because there are a number of advantages for distributed users.
Mark Sellers

Hi Bob,
From my perspective, direct file access on a single server that is backup up every night has a lot of advantages, including:
Easy and familiar access
Fast access for in-house users, slower but reliable access for remote users
Better security
Easier for users - double click and go
Simpler workflow - no copying files from a "master" source to a third-party cloud drive
Basically, extending the identical resources that are provided in the office through the server, to remote locations seems logical.
Why do you believe that Dropbox and other cloud based solutions are better? I don't see the advantages over VPN.

FCP X how to download and install over very slow connection?

Does anyone know if I can go to a public library, buy/download FCP X, copy it to a usb thumb drive and then come home and install it on my Mac Pro?
My only internet connection is thru a cell phone, which is slow and also has a data cap.

Welcome to Apple Support Communities
Probably you bought redeem codes. Open the Mac App Store, log in with your Apple ID, choose Redeem under "Quick Links" and insert a code. Final Cut Pro X or Motion will start being downloaded. Then, do the same with another code.
If it says that your code is not valid, contact with the seller that gave you these codes

How to prevent itunes from connecting to my IOS devices over wifi

I have a MBP retina that is set to sync (over wifi) with the iOS devices for myself and my wife: 2 ipads, 1 ipad mini and 2 iphones.
When I am launch iTunes in my other Mac - Macbook Air (mid 2010, 13inch, OS X 10.8.2), it will also start to connect the iOS devices - even though I am not using it to sync with my iOS devices.
How to prevent iTunes in my MBA from connecting to all the iOS devices in my house?
Thanks.

I configured all my iOS devices to sync with my MBP Retina (over wifi) - but the problem is that when I am using my MBA, the devices will also automatically connect to the MBA Itunes over wifi when I launch iTunes in the MBA.
Is there any way to prevent auto connection to the MBA?

Need an inexpensive way to eavesdrop on MPLS connection

We have a customer that needs to feed the data flowing over an MPLS connection into a software package that audits the content. They want to be able to see if inappropriate content is flowing and if so, to be able to take action on it. Any ideas on the lowest cost way to do this would be appreciated.
This client requirement raises issues about policies, but I'm not here to question policies, but to solve technical problems.

You will make the traffic over the core to flow via switche i.e.---> PE-Switch-P.. and enable SPAN and mirror the traffic to a software (ethereal/wireshark) and monitor the data flowing. Those software has the capability to capture the packets with the help of Outer Label(IGP), Inner Label(VPN) and Source/Destination IP address. So you can get the label values in the PE routers and map the values in the software which will show the data flow...

How LACP works over non-ethernet networks?

Hi all. Everybody knows how works LACP between two switches.
This is predictable wired links. But how it works in another, not clear ethernet networks? Supposing one link in LAG is over wireless transparent bridge. In this case values of packet delay, jitter and packet loss over one of the links differs from another.
Instead wireless bridge there can be IP/MPLS or SDH network for example.
How it works? Are there any tresholds for counters on links? Maybe any configurable parameters?

The configuration of each router should be provided in the Apple Support article link I provided you.
Basically you will not need to make any changes to the Motorola router just the AirPort Express.
Roaming Network Setup Basics
For the AirPort Express base station:
Setup the base station as a bridge. Network tab > Router Mode: Off (Bridge Mode)
Provide a unique Base Station Name.
The Network Name (SSID) should be identical to that of the Motorola.
If using security, use the same security type (WEP, WPA, etc.) and password. Note: It is highly recommended that you use WPA2 Personal for best bandwidth performance.
The following are the basic setup steps:
Power all the networking hardware down.
Perform a "factory default" reset on the AirPort Express. Note: You may have to perform this more than once to make sure they "stick."
Connect one Ethernet cable between the Ethernet port on the Motorola router to the Ethernet port on the Express.
Power up just the Motorola router. Verify that you can get Internet connectivity with network clients either by wireless or by wire connections to the Motorola router.
Power up the Express base station. Use the AirPort Utility to select it.
Configure the Express with the Network Mode option set to: Create a wireless network. (Note: Do NOT set it to "Extend a wireless network."
Set the Wireless Network Name, Wireless Security, & Wireless Password options to be exactly the same as that used for the Motorola.
Set the Router Mode to: Off (Bridge Mode).
Select Update and allow the Express to restart.
Once restarted verify that you can roam with a wireless laptop or iOS device between base stations and still gain Internet access.

TS3276 On received mail, I delete sender's name, address, etc. then forward it. The forwarded mail has a duplicate of the original mail, show original sender's name, etc. How to prevent the duplicate from being sent?

How to prevent duplicate of orginal mail (with original sender's name, address) being "attached" when forwarded?

Maybe I am mis-understanding what you are seeing.
When I forward a message, the receiver will see the original mail (unless I edit it, such as removing any previous sender's information) and the length will be the same as the message was before forwarding except for the added line "Begin forwarded message" (again, unless I edit bits out), and there will be no attached copy of the original message.
So when you say in your reply above "The orginal email with the sender's name and address was also sent with my forwarded email." do you mean:
a) that it is still visible at the head of the text of the message (which I was saying does not happen for me because "after hitting delete, the previous sender's information disappears." [and since] "it has disappeared, it cannot be in your forwarded mail." Disappeared means it is not there.
b) another copy of the original message is attached to the forwarded email at the end, either as an included file or as repeated text.
c) some other situation.
Sorry about the previous mis-spellings! I hope that we can get to the bottom of this.

How to prevent voice over saying the caller number or name automatically in iphone?

hi, i'm a new member of apple world,
i'm using voice over in my iphone 5s, when i receive a call, voice over automatically say the calling number or name with the ring tone, how can i set
voice over to prevent it saying the caller number or name ??

Same problem, which is extremely inconvenient because I like to use my earphones to listen to Pandora while I work. Not every time, but most of the time I plug in my earphones, the iPod software starts playing the last song that was played. Stopping the music via iPod or pressing the Home button for 10 seconds to force quit iPod doesn't stop the music as it will just automatically start playing again. Sometimes if I'm lucky, plugging the earphones in very quickly avoids this problem -- but like I said, it's a cross my fingers and hope I get lucky kind of thing.
I'm using the newer 3G model, which I've had for only about a month. I did not have this problem with my old 2G iPhone.
Someone in another thread said it's a hardware fault and suggested exchanging the phone for a new one. Can anyone confirm this?

How to prevent voice over saying the calling number ?

i'm using voice over in my iphone 5s, when i receive a call, voice over autamatically say the calling number or name with the ring tone, how can i set voice over to prevent it saying the caller number or name ?

It appears to be working as Apple intended. The manual says:
Moving recordings to your computer
You can sync voice memos with the iTunes library on your computer, and listen to them on your
computer or sync them with another iPod touch or iPhone.
When you delete a synced voice memo from iTunes, it stays on the device where it was recorded,
but it’s deleted from any other iPod touch or iPhone you synced. If you delete a synced voice
memo on iPod touch, it’s copied back to iPod touch the next time you sync with iTunes, but you
can’t sync that copy back to iTunes a second time.
Sync voice memos with iTunes. Connect iPod touch to your computer. Then in iTunes, select
iPod touch. Select Music at the top of the screen, select Sync Music, select “Include voice memos,”
then click Apply.
Voice memos synced from iPod touch to your computer appear in the Music list and in the Voice
Memos playlist in iTunes. Voice memos synced from your computer appear in the Voice Memos
app on iPod touch (but not in the Music app).
What yo can do is code the Voice Memos on the computer as something besides Voice Memos (Right click>Select Get Info>go to Option tap and change under Media Kind). When yo change it it will move the VM to the library for that kind e.g., Music if you coded it as Music)

How to prevent error message for material description in MDG material detail screen, when user click on check action

Dear Experts,
I have a requirement for making material description as non mandetory in change request view of mdg material screen.
I have done that using field usage in get data method of feeder classes, but still message is displaying.
This message 'Material description is mandatory is displaying with check action only, but not with save or submit after i anhance field property as not mandetory.
How to prevent error message for material description in MDG material detail screen, when user click on check action.
Thanks
Sukumar

Hello Sukumar
In IMG activity "Configure Properties of Change Request Step", you can completely deactivate the reuse area checks (but will then loose all other checks of the backend business logic as well).
You can also set the error severity of the checks from Error to Warning (per CR type, not per check).
Or you provide a default value for the material description, e.g. by implementing the BAdI USMD_RULE_SERVICE.

How to send joystick data over TCP connection

Hi all,
I am a long time Labview discussion forum user for learning, but this is my first time posting a question, I hope somebody can help me!
In the attached VI I am trying to send data from a joystick over a TCP connection. I can send data fine using the TCP examples (in fact the majority of my VI is just a copy of the example). However I am to the point where I do not know how to send all the data necessary (3 axis data, 12 buttons, and the POV data) over TCP. Strings, clusters, and arrays were never my strong suite and converting between them is a nightmare for me.
Basically I am trying to send each axis data (X,Y, and Z), button data (12 buttons), and POV data (the POV data will be calculated to adjust the position of a camera, so the immediate data is not important, I will add functions to add the change in the button movements to write a standing position for two servos [pan and tilt], for which that I will need to send over the TCP connection) over the TCP connection to control various cameras and motors. I don't know if it is posible to send that much data over a TCP connection in one write VI through a string, and also how to separate the string on the other side in order to control the client VI.
Again, the actual TCP communication I get, and can operate fine, just formatting all the data into a string (or whatever is required) so that I can unpack on the other side is the issue here.
Another question I have (not impotant to get the program running just might make it easier on me) is can a TCP server (which sends the data to the client) also recieve data back from the client on the same port ( for example sensor data and digital positions [on,off])? Or do I need to set up two TCP communication loops with the first client acting as the server on a different port than the first, which then sends the data to the original server, which also has a client TCP configuration in another loop? I hope this makes sense...
One final question.....I already have a solution to this but using labview for the entirety of this project would be nice. I use skype to stream 1080p video from a webcam to my computer so I can view live feed. Can labview do this? This would be awesome if so, I am just not sure if the communication protocols in use could support real time (or as close as possible to streaming) for 1080p video.
Thanks all in advance for your help,

Well, you cast the axis info cluster to a string, but then you cast it back to an array of DBL. Thatr's not compatible. You should probably cast it back to an "axis info" cluster of exactly the same type. Go the the other VI and right-click the cluster wire to create a constant. Now move that diagram cluster constant to the other VI and use it as type.
Your default ports don't seem to match. You seem to have client and server roles confused. In the sever you create a listener, but then you start sending packets, even though no connection is established. The connection needs to be initiated by the client.
Your client stops the loop the first time a timeout is encountered. Shouldn't that be more permanent? Also, please retain code clarity and avoid unecessary complexities. For example, replace the "not or" with a plain "or" and change the loop to "stop if true"

You can send as much as you want. The casting to/from string is the same as described above.

The primary function of a "server" is to wait for a connection and then communicate with the client once a conenction is established. An established TCP/IP connection is fully two-way and both sides can send and receive.

How to prevent contacts disappearing after FW upda...

Hi all, I would like to know how to prevent all contacts from vanishing after firmware update, can contacts be saved on memory card & retrieved or restored ? I have over 300 contacts & it would be a pain in the a** to restore it one at a time, thanks.

you can
a) back them up in your pc with PC Suite / SVI Cuite, and in the SD Card
b) Copy them all in your SIM Card (if not already recorded there instead of the phone memory
