Advantages of Running IPv6 in MPLS Core

Folks,
Cisco has 6PE solution for providers who have IPv4 backbones running MPLS and want to add support for IPv6.
My question is what is a New SP who wants to enable IPv6 in the backbone ( Loopback IP address, Ospf V3, IPv6 MPBGP,etc). Would this SP have any advantage???
To the best of my knowledge cisco still does not support MPLS VPN for IPv6, customer isolation is done using prefix list, I know juniper has support, any thoughts on why cisco still does not support IPv6 Vrf and if it has any plans to do it in the future would be hiighly appreciated?
Thanks

I see two questions in your posting.
1- What is the advantage of running IPv6 native all over your backbone.
The answer to that is it depends. If you are a transit provider only providing IPv6 to your customer then I see no advantage in running IPv6 natively in the backbone as 6PE does an excellent job at that. If you are a content provider then it is a different story.
2- MPLS VPN for IPv6 (aka 6VPE). This feature will be supported in the near feature. For more information on the road map, please contact your account team.
Hope this helps,

Extract report only runs on a single core

I am running the following extract report on a dual quad-core processor server with 32 GB ram and when I suppress empty rows the process runs on a single core which of course runs at 100% slowing down the process, but if I do not sppress rows all cores are used. Has anyone else experienced this or can i modify my report to improve performace?

One item unrelated to the DimBot issue:
If you have a time period that can be used to restrict on (for suppression), you can use the restrict approach rather than the sup missing, ala:
<RESTRICT (@DataCol(11) <> #Missing )
I'm not sure I would attempt this if you had to deal with multiple restrict's though -- I'm also not entirely convinced the savings would be substantial, but it could be based on the multiple core aspects.

Load-balancing in MPLS Core

How is load-balancing achieved in MPLS L3 vpns and equal cost multiple links exist to reach egress PE along with per-destination load-balancing enabled on interfaces.
I have tried to simulate the network below
Ingress PE--->P1--->>P2--->Egress PE
Multiple equal cost links exist between P1 and P2, cisco platform,LDP, IGP-ospf being used.

Hi,
Destination based load balancing in MPLS L3VPNs can be categorized into two scenarios:
1) multiple pathes between two PE routers
2) multiple access links to a single CE or site
Your question as I understand it was about the first scenario. So let me first quickly review how customer traffic is forwarded between VRFs on two different PE routers.
The VRF routing table will have BGP entries for the routes learned from the remote PE usually with next hop addresses being the remote PE loopback IP used for PE-to-PE BGP peering.
The traffic will be forwarded across P routers using the label for the BGP next hop.
Thus the load balancing accross the MPLS core in a first step is decided by the IGP, which has to insert several equal cost pathes into the global routing table for the BGP next hop networks (PE loopbacks).
Side note: MPLS traffic engineering in the core would allow for unequal cost load balancing.
The decision, which labeled packet to send across which path in the core is done by CEF using a hash algorithm. To achieve the same load balancing as with unlabeled IP traffic, a Cisco MPLS enabled router will look for the bottom label - the one with bottom-of-stack bit set to 1 - and try to determine, if the transported packet behind the bottom label is IP. If so, the hash is calculated for the customer IP header like for normal IP traffic. This ensures all traffic for a certain customer destination will always go through the same path. No unwanted packet reordering will occur.
Be aware, that the customer IP packet header will only be used for CEF hash calculation, no IP lookup will be performed, as core routers in MPLS L3VPNs do not have any knowledge about customer addresses.
As a side note: if the traffic transported is not IP (e.g. Ethernet over MPLS), the bottom label will be used for the CEF load balancing (e.g. the VC label).
For the second scenario - CE load balancing with multihomed CE/sites - it is first required to have two equal cost entries in the VRF routing tables. The difference will be the two different PE BGP next hop addresses. The first load balancing decision is the performed by CEF based on the IP packet received by the CE and the VRF routing table entries. Once CEF decided, which VRF entry to use, the required BGP next hop label (and the VPN label) is applied and the packet is transported across the MPLS core. load balancing there is done as described above.
Hope this helps! Please rate all posts.

BGP Best Practice / Private-AS vs. Public-AS in the MPLS Core

Dears,
We have recently aquired a large network with ASR9K as Internet Gateways and non-Cisco devices in the MPLS Core.
We would liike to know which is the best recommended solution to use Private MP-BGP AS in the MPLS Core or extend the IGW Public AS, knowing that the IGW will be in a VRF and not the global routing table. Moreover, the clients of the MPLS Core have their own BGP Public AS and would need to connect to the MPLS Core to obtain internet services from the IGW.
(Cust1)------EBGP------[VRF_Cust_1](MPLS CORE AS_2)[VRF_IGW]------EBGP-----(IGW AS_1) in the case of having a private BGP AS in the core
(Cust1)------EBGP------[VRF_Cust_1](MPLS CORE AS_1)[VRF_IGW]------iBGP-----(IGW AS_1) in the case of having same public BGP AS in the core
Waiting for your feedback and thoughts.
Thanks,
Michel.

Michel,
if your mpls core is also used for internet transit, then it is best to be a public AS.
if not, then you can leave it be and remove the private AS at your border routers.
If oyu are connecting multiple MPLS networks together to link L2 or L3 VPN services, I think it is easiest to have it all one AS, otherwise you end up with complex designs such as Carrier supporting Carrier (CSC) or Inter-AS option A (vrf lite), B (using vpnv4 at the inter AS gateay) or C (using vpnv4 at the interAS gateway with route reflectors in each AS peering with each other).

Anyone running Parallels on Mini Core Solo?

I've seen widely varying reports (but only a few, not enough to come to a conclusion) about how well (i.e. acceptable speed, or too slow?) the Parallels Desktop virtualization software (which allows running Windows alongside Mac OS X, rather like Virtual PC used to do) runs on the Core Solo Intel Mac mini, which is the only Intel Mac without the Core Duo CPU.
We need to get a Mini for the office, to run QuickBooks (only, no games or anything else); the Core Solo is within budget, the Duo model is beyond it, and more than we need otherwise.
Anyone here tried running Parallels on a Core Solo Mini? Care to share your experience?
Andrew Main

I’ve installed Parallels Desktop and WinXP on my Core Solo with 1GB RAM. I also have a MacBook so I have compared the two.
The Good News:
The speed of Windows in Parallels is what you’d expect from a basic Celeron PC with integrated video from a couple years ago. In other words, if you will be using programs with modest requirements such as word processing, spreadsheet, or database with medium data sets you’ll be fine. Anything that requires graphics acceleration...forget it. Screen redraws are slow because they are done through the Mac. I don’t mean you can watch each pixel be written but you can watch the screen redraw.
I have two tasks that require a PC - one is accessing a .NET based website that only works in WindowsXP and Exploder 6. The day that company has a viable competitor that doesn’t require Exploder we jump. The second is a data mining program. My mini and Parallels Desktop handle this just fine.
The Bad News:
Installing WinXP was something of a challenge and it was only through Parallel’s fantastic forum and tech support that I finally succeeded. But remember - I was on the cutting edge at the time working with a beta product. Parallels ships with a disk image program. I’ve found that it is best to make a disk image of the installation CD rather than use the CD itself. This applies to all CDs.
I also found it impossible to update to WinXP SP2 - my computer always hung during the process. (That may have been a glitch with early beta releases, I don’t know.) Luckily at work we had a WinXP w/ SP2 install CD - and commercial license - that installed without a hitch. But be warned - installing WinXP on a core solo with Parallels is slow. Start in the morning and keep an eye on the screen as it progresses - and don’t expect to use the computer for anything else. The installation will be using 95-99% of the CPU.
BootCamp vs Parallels:
In a word, significant. I’ve not done any benchmarking but when you run WinXP natively you realize just how much horsepower Parallels and OS X is taking away from Windows. Not to mention how much faster the screen redraws.
Differences between Core Solo and Duo:
Night and Day. It is like the difference between running Windows with an older Celeron and a new Pentium (excluding screen redraws which are slow because they are done via the Mac’s graphics package rather than accessing video directly.) On the mini, when I am processing data with the data mining program I can’t use the mini for anything else. Running the same process on my MacBook I can surf, read email, play a couple rounds of Soduko, whatever.
Conclusions:
If your budget is for a core solo consider using BootCamp rather than Parallels. The speed difference isn’t as significant as between solo and duo but it is significant. The Intel Macs boot quickly enough that your downtime isn’t tremendous. Having said that, in my own circumstances I find the speed of Parallels on my mini to be sufficient that I chose it rather than BootCamp. You might also want to consider a refurbished rather than a new core duo. Hope this helps.

L3 VPN and MPLS core

Hi all,
1) I am new to MPLS and trying to configure a scenario in a non production environment. Is it possible to have L3 VPN's without using BGP in MPLS core network? For some reason I am more inclined to use RIPv2, EIGRP or OSPF in the core.
2) Is it possible to use 2600 series router as PE?
Thanks in advance.

hi SHAH
to add to the nice cooments in the discussion
the BGP used with mpls and L3 VPN called MP-BGP
the VPN in with VRFs, RD and RT each one add to the ip packet an identifier to distingush the packet with the provider network from other packet and make it uniqe to pass these identifiers from router to router especiallt from PE router to PE router u need the BGP (MP-BGP)
hope this helpful

MPLS core questions

Hi,
I want to know the answers for the following failure scenario
1.Unknown LSP connectivity problem: LSP connectivity problem ,Data plan issue, or unknown cause
2.Distributed LFIB table discrepancy: There is a discrepancy in the LFIB table between the route processor and line cards
3.Distributed LFIB table discrepancy: There is a discrepancy in the FIB table between the route processor and line cards

hello dear mohisaxe,
so sorry for the late response, yes we plan to use them on separate ports and both CE and use the same line card as both customer and MPLS core facing.
just another quick question i have here:
1- as Mr. Xander's information, MOD80 line card has 2 typhoons each of them can accommodate 32K PPPOE sessions with limitation of 64K limit per line card.
2- as we have MOD160 line card with 4 typhoons, do we have the same limitation as above?
thanks for your support :)

Is there any way to make a Classic program run on a Intel Core Mac Mini?

My mom just got a new Mac Mini with the intel core processor and she wants to be able to run a rabit pedigree program from her ancient little mac that ran OS 7. Now it says that you can't run classic programs on the intel core processors, but is there any way to get around this? Say converting the application some how, or maybe even installing OS 9 some how as an alternate operating system or any such thing? Or should my mom just start looking for a different pedigree program and start reentering all of her information now?
Mac mini Mac OS X (10.4.7)

Try this, UneasySilence.com has a guide on how to use SheepShaver to run Mac OS 9 on an Intel Mac.
http://www.gibix.net/dokuwiki/en:projects:sheepshaver
"Who said you can't use MacOS 9 because you have an Intel Mac? It is completely possible with a little bit of tinkering, and a really cool universal application called Sheep Shaver, which came to us via a tip from Kazaki. Sheep Shaver is a full speed 'Classic' emulator for Windows, Linux, and Intel based Macs, that runs older MacOS's at shockingly full speed!"

Best Practice QOS in MPLS core

Hi.
Wath is the recommendation in configuring QOS in the core mpls (PE-P)
we have a mixture of traffic of data, cell signalling, O&M, voice R4, IVR.etc. We have 7600 as PE and 12000 as P. The PE's have SIP-GE and WS-GE cards against the P. In some cases the traffic goes through two P's connected via SIP-GE cards. I Had seen that the WS cards have some special considerations about QOS.

Hi,
Here is a good starting point regarding the best practices:

Forcing processes / JVM to run on specific CPU / Cores seamlessly

I'm running 4 different performance sensitive applications on a 2 CPU / quad-core 3GHz HP with solaris x86.
3 applications are java, 1 is C.
I'd like to force each of them to run on a specific (and different each time) CPU or core.
I've read about prstat / prset / pbind, however I find it quite inconvenient to use.
I'd like to add something to my start scripts so that they seamlessly always start on a different cpu / core...
any idea / link ?
thanks

Please describe the problem in as much relevant detail as possible. The "etrecheck" fad hasn't made that step any less necessary. The better your description, the better the chance of a solution.
For example, if the computer is slow, which specific actions are slow? Is it slow all the time, or only sometimes? When did it start to be slow? Did you change anything just before it started? Have you seen any alerts or error messages? Have you done anything to try to fix it? Most importantly, do you have a current backup of all data? If the answer to the last question is "no," back up now. Ask if you need guidance. Do nothing else until you have a backup.

Labview 2011 executable does not run on AMD Quad Core

I have recently bought a brand new Toshiba Satellite with AMD Quad Core- A8-4500M 1.9GHz processor and Windows 7 OS. It does not run any labview executables. It runs on all my Intel machines without any problem. This is the first AMD ever bought (and the last). I need help in resolving this problem.
When I run an exe on the AMD, under Task Manager\Processes, I do see *.exe process running, but the Memory usage goes up and tops off at 100% and then it returns to 0. It's like a saw tooth waveform of memory usage, as if it's looking for some missing files. I have cleaned up the computer twice now and even a simple Add Two Numbers.exe does not work on this AMD.
Any clue, anyone? please?

I believe you are running into the problem described in this KB.

Will illustrator cs2 run on imac quad core?

will illustrator cs2 and photoshop cs run on the new imac quad core? if not, which versions will run?

Only the very latest versions will/could have updates for 10.7 Lion as the OS was just released and doesn't run "Rosetta/PPC" based programs which those most likely are.
Guess you milked Adobe for as long as you could, perhaps you can buy a used machine?

7600 as Backbone router for MPLS core

I have 7600's and 7500's in my backbone and 7200's on the edge. My question is that when I look at the feature navigator the 7600 with Sup 720 is missing a lot of basic features required to be a core router of an MPLS Backbone. Features like Traffic engineering fast reroute, MPLS enabled Netflow are missing on this platform, is this platform not a good candidate to be a Backbone router for a service provider offering MPLS services??? 7500 on the other hand it seems 7500 seems to have support for the MPLS related features.
