Merging of lsps

hi,
what do you mean by merging of lsps..?
In what all scenarios do we use this..?
How do we do this..?
Thanks in advance,
Thomas.

Hello Thomas,
the term "VC merge" is used in cell based MPLS. There ATM cell headers (VPI/VCI) are used as labels. Basically LVCs are setup through f.e. LDP. The main issue VC merge does address is the comparably low number of VCs supported per interface in ATM routers and switches. Assume 100 routers attached to an ATM network - this could mean roughly 10000 LVCs.
VC merge means, that an ATM switch has several incoming VCs (VPI/VCI) mapped to one outgoing label (VPI/VCI). Thus on the outgoing interface towards one router R1 only one VC is created and not 99 (a separate one per other router).
In cell-based MPLS you can configure this through the command "mpls atm vc-merge".
The detailed description can be found at: "MPLS over ATM: VC Merge"
http://www.cisco.com/en/US/tech/tk436/tk798/technologies_configuration_example09186a00801c2d73.shtml
In frame-based MPLS the downstream router distributes a single label per destination network. So all upstream neighbors will use the same label. This could also be called "merging of LSPs". As this is the default, there is no specific configuration required.
Hope this helps! Please rate all posts.

  • Override IS-IS LSP password on interface

    I have a router which uses a Keychain for authentication, configured under the ISIS process, and i want to disable this on one interface.
    Therefore all ISIS interfaces use this keychain. I now need to add another interface into the ISIS process, but this one needs the LSP password authentication disabling 
    under the interface settings.
    The issue is that the router network uses all ASR9000 series kit, and all ISIS instancies are authenticated by the keychain. Now we need to add an ASR1001 router onto a new link, but cannot get the ISIS authentication to operate on that path. I wish to disable the authentication on this path, I'm away from site so dont have access to the routers, and the manuals don't indicate how to override the process setting at an interface level.
    I'm back on site Monday morning to continue with this, can anyone tell me the commands for this?
    The code version is 4.3.0

    Hello aacole,
    IS-IS Authentication can be configured under interface configuration (isis password ), under IS-IS process for an area (area-password ) or for an entire IS-IS domain (domain-password )
    These three could be combined depending on your need. In this case, you have some options for disabling IS-IS Authentication in the link between the ASR9000 and ASR1001:
    1-Disable IS-IS Domain Authentication on all routers: no domain-password under IS-IS process.
    2-Option A: Disable IS-IS Area-Authentication on all routers within the area: no area-password under IS-IS process. Later you could configure IS-IS Interface-Authentication in the desired secured interfaces, excluding the link between ASR9000-ASR1001
    2-Option B: Configure Multiarea IS-IS and disable IS-IS Area-Authentication in the area of the ASR1001. For this you'll need to configure ASR1001 in a different area and merge the areas by configuring multiple network entity titles (NETs) in the ASR9000
    Note: Step one could be skipped if you configure the new ASR1001 on a separate VRF.

  • Questions on Merging Dis-similar Data Types...

    I am using Web-I version 11.5.8.834 (We do not use the Crystal Reports module, all of our reports are built with Web-I).
    I have two questions:
    Question 1: First I am attempting to create a report from two different universes and need to merge a dimension from each universe.  The two dimensions have similar data, but one is set up as a "string", and the other universe has the same data set up as a "number".  Our IT department creates and maintains the universes and I have requested that one of the dimension data type be changed to match the other, but I am told that other users have already set up reports using these dimensions and to change them at this point might cause a problem with their reports.  So my first question is: Can two separate dimensions be setup within a single universe, using the same data field, each having different data types (e.g., a field with numeric data be set up as a "string" and a second dimension be setup as a "number")?  If this works, I can make a recommendation to our IT department to do this and I will not have to resort to Question 2.  but just in case, here is Question 2:
    Question 2: I have two other dimensions that I might be able to use, but it requires creating a variable and "trimming" data off of each of the fields.  The first universe is a part number with three alpha characters followed by four numeric characters (PRT1234).  The second universe has a serial number, in which the first four characters match the last four characters of the other universe (1234-00111).  If I trim off the first three characters from the first universe using a variable (=right([Part_Number];4), and trim off the last six characters from the second universe using a variable (=left([Serial_Number],4), the variables will have matching data.  The second question is: Can variables be merged?  I've tried, but it isn't working so far.  If so, can someone give me some hints on how to do it?

    Charles,
    Can variables be merged?
    No, local variables cannot be merged.  The manipulation must be performed at the database level via Designer before the data comes across to the report.  As an aside, your IT deparatment can create "new" objects just for you, placed in the list under a separate sub-class that manipulates the data to your liking and will not upset other users who already built reports using the original columns of data.  I guess my point is that you can have multiple objects placed in your universe that derive from the same column in a given table -- user A has it per their flavor and user B has it per his flavor.
    Thanks,
    John

  • Can I merge several different Verizon plans (different family members each have own plans) into one plan (i.e. can I take over all their lines), if all lines on all plans are on Edge?

    I was originally told by Verizon that if I joined, I can eventually take over the lines of various family members.  Now that I've joined, and my family members all upgraded their phones and are on Edge, Verizon is telling us that we can't merge into one plan (because Edge lines can't be transferred to another account).
    Is this true, and, if so, what is my recourse since I was lied to.

    Well, yes and no (as far as being lied to).  I asked on several occasions (I have the chat transcripts to prove it) if there would be any issue if the lines were all already on Edge, and was told each time that under no circumstances would there be any issue.  The latest being today (I know it's after the fact, but I wanted proof that this is what the chat people are saying).  I asked "I have currently have an account with 3 phones on Edge.  My brother and his wife, and my parents, also have plans all on Edge.  I would like to 'take over' their lines.  I want to make sure there is no issue with the Edge plan and that I can simply 'take over' their lines with no problems."  I was told "Yes. That would be correct."  Again, this is what I was told in the past as well (my original post didn't make clear the timing of the chats and upgrades to Edge..).  Every time I chatted I mentioned that the accounts were going to be on Edge or (later on) were already on Edge.  Even before my family members upgraded to Edge, not one single chat or phone representative (and my brother asked the same thing in a store) mentioned NOT to upgrade to Edge because it couldn't be transferred.  Everyone just said yep, no problem.  The ONLY reason I even joined Verizon (I was on Straight Talk) was because of the More Everything and Edge plans (we wanted a family plan with 6 people and over 10GB so we'd each save $25/line).  Otherwise I never would have joined Verizon and my family wouldn't have upgraded either.

  • HT4910 Have two phones with same apple id as I got one for my hubbie .he tried to back up his numbers in I cloud . Our contacts have now merged and neither can delete from our phone without it coming off the other . Any ideas how we can stop this

    Have two iPhones with the same id as I got hubbie one in week and when I got it they asked for email address so I gave the one we use, so when my husband started phone up he just put my password in. When he tried to back his numbers on iCloud they all appeared on my phone and now I can't delete his numbers without them deleting on his phone as well . Any help would be appreciated.

    You'll have to migrate one of the phones to a different account, then delete the other person's data from each account (you can continue to share the same Apple ID for purchasing from the iTunes and app stores). 
    Decide which iPhone will be keeping the current iCloud account.  On the one that will be changing accounts, if you have any photos in photo stream that are not in your camera roll or backed up somewhere else save these to your camera roll by opening the photo stream album in the thumbnail view, tapping Edit, then tap all the photos you want to save, tap Share and tap Save to Camera Roll. 
    Once this is done, go to Settings>iCloud, scroll to the bottom and tap Delete Account.  (This will only delete the account from this phone, not from iCloud.  The phone that will be keeping the account will not be effected by this.)  When prompted about what to do with the iCloud data, be sure to select Keep On My iPhone.  Next, set up a new iCloud account using a different Apple ID (if you don't have one, tap Get a Free Apple ID at the bottom).  Then turn iCloud data syncing for contacts, etc. back to On, and when prompted about merging with iCloud, choose Merge.  This will upload the data to the new account.
    Finally, go to icloud.com on your computer and sign into each iCloud account separately and manually delete the data you don't from each account.

  • I have three itunes accounts and want to merge them

    I have three iTunes accounts and have found that at times we have purchased multiple of the same items as a result.  Can I merge two of the lesser accounts by gifting or otherwise migrating the songs, apps, videos etc to one master account?

  • I brought my itunes library onto a mac from a windows machine and now i have two separate libraries.  How can I merge them?

    I moved to Mac from a Windows machine where I had downloaded all of my CDs into iTunes.  When I got my Mac it only put my purchased items into my library.  So I merged my windows library and it created a whole new user account with that on it.  I now have two libraries and can only sync music with one account or I lose all of my imported CDs.  Help!  How do I merge them. 

    The easiest way is to get both computers on your home network and copy the files over the network. It's easier than you think
    Check this earlier thread:
    [How do I move my itunes library to new computer|http://discussions.apple.com/thread.jspa?messageID=7937172&#7937172]
    That thread mentions Target Disk Mode, which won't help moving from a PC to a Mac. But you can use file sharing to copy the files.
    As the articles all say: don't forget to de-authorize your PC before you get rid of it.

  • I have 3 iTunes accounts and want to merge them into only one of them. I also have money on all 3 accounts

    You cannot merge the accounts.
    Sorry.

  • I have two apple ids somehow, probably from two mobile and two computers - how do I merge them into one account so they all work with iCloud?

    Somewhere, somehow, between two mobile and two macs, I ended up with two apple ids. I figured that this was the root of my problem to syncing. So, I am syncing Mail, Contacts, etc through the one account that I bought storage on this year in iCloud. I want to merge the two accounts, since many of my apps were purchased with my other id. Apparently, Keynote will not merge files since the app was bought with the second id, not the id I am using for icloud.
    What to do??? I read, in the forums, that I am definitely not alone. I always had the id I used for the Apple Store to buy iTunes items, and then apps. The other id, that I am using for iCloud was based on my iDisk id, and apparently I set up as a separate account. The much failed iDisk account appears to be the one that I wish I never got involved with. Should I feel the same way about iCloud. If I cannot merge the two APPLE accounts from the same person (ME!!!), then many dropbox really is the answer for my file sharing needs.
    Please help me decide.

    To begin with, I would like to try to explain Apple's confusing nomenclature in regard to iCloud.
    Apple have called the whole cloud thing iCloud, there are a number of features under the iCloud umbrella, some of which require their own login. iTunes is one of these, another is what Apple have unfortunately also called iCloud too.
    You can use the same Apple ID (account) to login to both iCloud and iTunes, but you don't need to and often users will login to each service using a different ID.
    The part that you need to remember is that the services available when you log into iCloud are completely different and unrelated to those when you log in to iTunes. Your iCloud login enables mail, contacts, calendars, find my phone, Back to My Mac, Documents & Data sharing and photostream, it does not affect any of your iTunes services.
    To avoid confusion when discussing your problem, when I mention iCloud, I am referring to the services under the iCloud login, Whereas I will refer to the whole cloud thing as The Cloud.
    To go back to your question; you cannot merge accounts, but perhaps using one account for iCloud and the other for iTunes will resolve the majority of the reasons you needed to merge to begin with.

  • I have iTune accounts under two separate Apple IDs.  Can I merge them into one account under one ID?

    I have iTune accounts under two separate Apple IDs.  Can I merge them into one account under one ID?  I have purchased music and video in both.

    No, it is not possible to merge accounts.  Choose one as the primary account and keep a local backup of all purchases so you don't get into the mess where you encounter a 90 day freeze on re-downloading past purchases from multiple accounts.

  • I have two apple Id accounts how do I merge them into one account

    you can't merge Apple ID's

    I have multiple Apple IDs. Is there a way for me to merge them into a single Apple ID?
    Apple IDs cannot be merged. You should use your preferred Apple ID from now on, but you can still access your purchased items such as music, movies, or software using your other Apple IDs.

  • How can I merge all of the new FF windows that are open into one window with multiple tabs? Safari has a merge windows feature that I like. This is really nice when conducting reasearch on multiple sites at the same time.

    When I clik on weblinks they all open into new windows making it somewhat painful to clik on window in the menu bar to go to each new page. I would rather have a feature that would allow me to merge all of those individual windows into tabs within one page.
    == This happened ==
    Every time Firefox opened

    Thank you. That worked. I was able to open 1 window with multiple tabs. Thanks cor-el!

  • How do I merge multiple ipod libraries on one laptop?

    We have over 5 ipods in the family and need to sync all their content to one library on one laptop.  Every time I plug in an ipod to the laptop, it will only show that ipod's library.  I have tried to merge the libraries, but end up losing songs/apps/etc.  At present, for example, I can see many apps in the iTunes library, but they will not sync with the ipod that is plugged in.  Thanks for any help.

    Only two ways currently - the latest versions of iPhoto and of Aperature (which can nopen current iPhoto libraries and can merge libraries) or the paid version of iPhoto Library Manager - http://www.fatcatsoftware.com/iplm/ -
