Does OSPF support IP LDP Fast Reroute Loop Free Alternate?
I only saw examples with IS-IS protocol. I have got ARS9010 with IOS XR 4.01. OSPF is in MPLS core and I need failover below 1sec. The core will state 5 ASR in ring.
Yep, it's supported in IOS XE, XR and 15S. Check the feature navigator to see if it's supported on your platform & release, but basically it's in almost all XE & XR boxes plus 7600 & ME3600/3800, and probably other stuff running 15S that the FN doesn't mention.

Configure IP LDP Fast Reroute Loop Free Alternate - OSPF
Hi,
The below link is giving example to configure IP LDP FRR LFA using IS-IS as an IGP.
http://www.cisco.com/en/US/docs/routers/asr9000/software/asr9k_r4.3/mpls/configuration/guide/b_mpls_cg43asr9k_chapter_01.html#reference_063CBD50AC624F28B69D6B2173B53A75
Is it possible the same while having OSPF as an IGP ?

MSI 645 ULTRA - DOES IT SUPPORT FAST WRITE -
MSI 645 ULTRA - DOES IT SUPPORT FAST WRITE -
coz i want to enable it so i can get higher 3dmarks score.
so i'm wondering if it supported but i think it doesnt but not sure.
k thx.I am assuming here, that it is always on and that turning it off isnt a option via the less than robust bios' that MSI gives us. That being said, there is a utility called NVMax that allows you to switch it on and off as well as 2x/4x agp, assuming again, that you have a NVidia graphics card.
Try that Emazy, Im curious to see if you get lockups like I do when I check it off. For me at least, it appears to be on, but greyed out. Sisoft says that it is capable of fastwrites but not enabled.
As I mentioned before and as Assaf confirmed, the difference is negligeable and in most cases causes to instability.
I think Fast Writes was as big a hype as MMX was. :] -
IP-Fast Reroute with MPLS remote LFA tunnels
I have a simple ring network with 4 3600Xs with IP/MPLS 10 gig backbone between all units (with OSPF running in the core). Per the 3600 design guide I turned on IPFRR under OSPF for fast reroute of traffic around faults. I have a l3vpn on the 3600s that I'm using to test. The FRR works quite well when the repair route is a ECMP (equal cost multipath) route, I don't even notice an interruption in ping between l3vpn sites when an 'active' link goes down.
The issue arises when the repair route is a remote-LFA (loop free alternative) MPLS tunnel. I've done a few tests, and the failover time when the repair route is a remote LFA tunnel is the same as when FRR isn't turned on at all, it's just the normal route convergence time and there is a significant traffic interruption (as compared to FRR when an ECMP route is the repair route).
The thing is I'm not quite sure how even to diagnose this. I was thinking that maybe the remote FLA tunnel was using the link that failed, so it in essence was 'down' as well, hence the traffic interruption as routing fully converged. But I looked at the remote-LFA interfaces, and as much as I understand them they are taking the right path out of the router anyway (that is, away from the link that would fail in order to activate the remote-LFA route).
Are there any resources or tips to help troubleshoot why these remote-LFA tunnel repair routes don't seem to be working well?Thanks for the reply Nagendra. When you ask if I've seen the back path installed in RIB/FIB, I'm not exactly sure what you mean. I do see repair paths referncing remote LFAs on both the 3600 that would be the source and the destination of the test traffic. Like this:
* 172.16.0.3, from 10.10.10.3, 01:55:50 ago, via TenGigabitEthernet0/2
Route metric is 2, traffic share count is 1
Repair Path: 10.10.10.4, via MPLS-Remote-Lfa40
and on the other router:
* 172.16.0.2, from 10.10.10.1, 01:56:34 ago, via TenGigabitEthernet0/1
Route metric is 2, traffic share count is 1
Repair Path: 10.10.10.2, via MPLS-Remote-Lfa32
If you're looking for some specific command output, let me know. -
Hi,
One quick enquiry, does 7600 platform support MPLS Fast Reroute.
Practical inputs would be of immense help.
Thanks
Cheers
~sultanThe MPLS Traffic EngineeringFast Reroute MIB provides Simple Network Management Protocol (SNMP)-based network management of the Multiprotocol Label Switching (MPLS) Fast Reroute (FRR) feature in Cisco IOS software.
The Fast Reroute MIB has the following features:
"Notifications can be created and queued.
"Command-line interface (CLI) commands enable notifications, and specify the IP address to where the notifications will be sent.

MPLS TE Fast-Reroute question?
Hi:
I am trying to configure the mpls te fast-reroute command but the router complains!!
I am running 12.4 Enterprise on a 3640.
Does this only work on a 7200 and up?
Thanks.Niraj,
The 3640 doesn't support FRR. It does support traffic engineering but can not be used as the Point of Local Repair (PLR) router, which is the router where the backup tunnel is configured.
Hope this helps, -
Installed graphics card does not support the opengl features recommended
I've installed FCP6 on my PowerMac (PPC G4 DP 1.25GHz), and when I run it, I get a warning ("...installed graphics card does not support the opengl features recommended...") and the program ends. The graphics card is the ATI Radeon 9000 Pro (64MB)
I'm looking for a definitive answer regarding my hardware compatibility with FCS2 (specifically, FCP6). I'm NOT looking for an answer along the lines of: your system is too old to run this.
I've checked the minimum system requirements from the apple website (http://www.apple.com/finalcutstudio/specs/
and http://www.apple.com/finalcutstudio/download/):
* A Macintosh computer with a 1.25GHz or faster PowerPC G4, PowerPC G5, Intel Core Duo, or Intel Xeon processor
* 1GB of RAM
* An AGP or PCI Express Quartz Extreme graphics card (Final Cut Studio is not compatible with integrated Intel graphics processors)
* A display with 1024-by-768 resolution or higher
* Mac OS X v10.4.11 or later
* QuickTime 7.3 or later
* DVD drive for installation
I have all that stuff. What I'd like is to know which component of my system is FCP6 complaining about (vis-a-vis the error message above), alternatively, if someone has had success with a similar configuration, I'd like to know anything they think might help.
Thanks in advance for any helpful advice you may have.The minimum would probably be an nVidia Fx5200 or an ATI 9600...

TestStand Open SQL Statement does not support SQL's ORDER BY clause???
TestStand 1.0.3
Windows 2000 SP1
SQL Server 2000 Personal
You've got to be kidding me...
It appears that the built-in TestStand Open SQL Step does NOT support the
"ORDER BY" clause in the SELECT statement, even though the documentation
says it does. Is this true?
I have an Open SQL Statement query:
"SELECT * FROM [MyTable] WHERE ([Batch ID]=1234)"
it works fine, returning a correct record count 120 records. If I change
the Open SQL Statement query simply by adding an ORDER BY clause, such as:
"SELECT * FROM [MyTable] WHERE ([Batch ID]=1234) ORDER BY [MyField] ASC"
it returns a record count of zero. I know that "MyField" exists in the
MyTable table and contains valid data. The
second query works fine in SQL
Server Enterprise Manager.
Am I missing something? Is it true that the TestStand Open SQL Step does
NOT support the "ORDER BY" clause? If not, what &#$!ing good is it and why
does the manual state it is supported? Is there any other way using just
the TestStand steps to order a database recordset on one or more fields?
Any help would be appreciated.
Grrrrr....

I've been doing some experimenting over the past couple of days. Simple,
one-table queries seem to handle the ORDER BY clause fine. Th
ings seem to
get messed up when I try multi-table queries with ORDER BY clause with the
TestStand database steps. I get no errors but the returned record counts
are always 0 with the ORDER BY and positive without the ORDER BY. The exact
same queries work fine in Visual Basic/ADO and the SQL Server Query
Analyzer.
> Questions:

Hmmm... yes data IS getting returned (at least on the two instances I just
checked), but the record count is always zero. I was not proceeding with
processing if the record count was 0.
Still... I don't know how to loop through the recordset without knowing how
many records there are an not eventually generate an error by passing EOF.
Is there another way using the TestStand database steps to determine a) the
number of records in the recordset or b) when I'm at EOF?

Everything on the Advanced tab of the Open SQL Statement step is set to "Use
Default".

CS4 does not support XP 64....
I just read this from Curt:
"Premiere CS4 does not support XP64. It supports XP 32, Vista 32, or Vista 64 on PC"
Why not? and will it be supported in the future?
Will it work with Windows OS 7?It works with xp64 but it's not supported. Vista 64 is what the program is optimized for. I have Windows 7 64 as test OS and it works perfect so far. Right now if I'm doing an After Effects project I'll do it in Win 7 64 because it is faster. Hands down.
I know there's a lot of hate for Vista but XP is going the way of Windows 2000. I know some people hate that but technology is what it is. I wouldn't be surprised if there is no support for xp when CS5 comes.
Actually I kinda wish 32 OS would die off so 64bit will become more widely supported. -
"Your computer does not support video chatting." Sometimes.
Hi, I'm on a MacBook late '08 and my pal has some earlier macbook.
We are on each other's bonjour list. The problem is that sometimes we can have a video conference no problem, and at other, random times, the option is grayed out, and if I go to preferences, the iSight green light goes on, but the window says my computer does not support video chatting, and that's the end of the story. How do I troubleshoot that? Thanks.Hi,
In the 5 years since iChat 2 came on the scene I have only managed 3 Video chats with people on Satellite connections.
The Issue is the time it takes to bounce the Signal Up and back to the Host server.
When you send for a Web page you send little data packets of requests.
Your computer does not send the next until the first is acknowledged.
It tends to improve once it is started and you may notice any downloads you do seem to get faster the longer they are going.
iChat requires for Video chat that the packets are almost Instantly responded to/acknowledged and most domestic modems do not do this.
Some commercial servers provide a Buffer at one end or the other that acts like the acknowledgement was sent speeding up the process and effectively getting the fastest service you can get out of the connection.
Speed testing your Connection tends to take long enough for the Acknowledgement issue to be reduced and will tell you the max speed you will possibly get
http://www.speedtest.net/ but not the start up speed.
With some services you can pay for the Buffering (I forget the actual name for it)

DRG-11110: matches does not support functional invocation
Hi all,
We are working on the some prototype and we hit this road block.
When 'matches' was included with other conditions in query and used in pl/sql we are getting this error.
Oracle Text error: DRG-11110: matches does not support functional invocation
We tried including the hint /*+ index(t2 t2x) */ * (t2 table and t2x index ) in query but it didn't help.
The query works fine from SQL developer, but included in pl/sql gives the error 9 out of 10times.
Is there something that anyone can help
Regards,
Chaitanya.The optimizer tends to choose functional invocation, which will cause the query to fail, when the structured portion of the query is most restrictive. So you will need to stop it from selecting what might otherwise be the most efficient plan at the times when you might have otherwise gained the most performance benefit from it. You want to try to force the optimizer to use the domain index to select the rows based on the matches criteria first, then evaluate the other conditions. You will need to experiment with things like your date filter to see if that causes funcitonal invocation or not. It will depend on how restricitve that is, whether there is an index on the date column and whether there is a small enough amount of data to do a full table scan benficially. You might benefit from hints but the "rownum > 0" seems to have the most consistent effect. You can use "explain plan for" on a query that fails to see what it was trying to do. Notice the difference in the execution plans below for the first failed query and the second working query that uses the domain index.

Does WCCP support traffic from different VLANs(mapped to VRFs)?
Hello,
I have the following scenario from the WAN to the Data Center and from the WAN to the Branch:
1. Router 2800/7200 with three (3) MPLS VRFs (VRF Lite)
2. Switch 3750 with three (3) WAN VLANs (one for each VRF) and three (3) LAN User Traffic VLANs (one for each ASA Context) and one WAE VLAN
3. WAE with WCCP enabled for one VLAN in the switch
4. ASA with three (3) Contexts
5. Three (3) Internal LANs (one for each Context)
In summary, there are three flows of traffic which are separated along the way from Branch to Data Center. WAEs are working for one VLAN(VRF1) and WCCP is enabled at the 3750 Switch to do the redirection (not in the router). The question is: does WCCP support traffic from different VLANs (similar to inline 802.1Q) and handle all three flows separate? If so, what should the configuration be at the switch and the WAE?
Thanks.The VRF awareness for 12.4(T) is still probably 8-12 months out. VRF aware WCCP features are definitely in the pipeline, but nothing has been publically published on availability timelines.
It's now publically available on the forum... but , I've only found it on the 3750 and 3550 documentation.
at the 3750 you will need to place the redirect statement on each of the VLANs, ip wccp 61 redirect in

Fast-Reroute on a ring with Gig Interface
Hi,
I'm trying to setup a fast-reroute option on a 4 routers ring connected through gige with OSPF.
The main idea is to be able to use xconnect between A & B for normal route with a backup through C & D in case of Gig failure AB.
I created two tunnel as follow on A
interface Tunnel50
ip unnumbered Loopback0
tunnel mode mpls traffic-eng
tunnel destination b.b.b.b
tunnel mpls traffic-eng autoroute announce
tunnel mpls traffic-eng priority 2 2
tunnel mpls traffic-eng path-option 1 explicit name b-fast
tunnel mpls traffic-eng fast-reroute node-protect
interface Tunnel51
ip unnumbered Loopback0
tunnel mode mpls traffic-eng
tunnel destination b.b.b.
tunnel mpls traffic-eng autoroute announce
tunnel mpls traffic-eng priority 5 5
tunnel mpls traffic-eng path-option 10 explicit name b-low
and configure A to B interfaces with
mpls traffic-eng backup-path Tunnel51
ip rsvp bandwidth
router ospf
mpls traffic-eng router-id Loopback0
mpls traffic-eng area 0
Same kind of conf on B side...
Well, if I shutdown A to B interface, the fast-reroute doesn't seems to operate and the xconnect resume on a ospf convergence base latency.
Should I also create tunnel A-C, A-D, B-C, B-D, ... like a full mesh ? or point to point on a ring AB, BC, CD, DA ?
Thanks for your help.
LaurentI tried a xconnect between br01 and br04.
Routers are on a ring : br01(ge3/2)--(ge3/1)br03--br02--br04(ge3/2)--(ge3/1)br01
tunnel50 is the straight route and tunnel 51 is the low route

Hi,
i am trying to set up TE tunnels with Fast Reroute protection. As i am using FastEthernet and GigabitEthernet links i need to use RSVP Hello for link or node failure detection.
I have a little problem understanding and properly configuring the rsvp hello feature. The topology looks as follows:
PE1 - P1 - PE2
| |
P3 ----------- P4
I am trying to set up fast reroute to protect the connection PE1-P1-PE2 with backup path PE1-P3-P4-PE2. Both primary and backup tunnels are set up and working. I configure RSVP Hello on the link between PE1 and P1 with following commands on PE1 and P1:
PE1#configure terminal
PE1(config)#interface Fastethernet 0/0
PE1(config-if)ip rsvp signalling hello
PE1(config-if)ip rsvp signalling hello refresh interval 50
P1#configure terminal
P1(config)#interface Fastethernet 0/0
P1(config-if)ip rsvp signalling hello
P1(config-if)ip rsvp signalling hello refresh interval 50
After issuing the sh ip rsvp hello instance detail command on PE1 i can see that the RSVP hello session is active:
Neighbor 195.10.3.1 (router ID: 3.3.3.3) Source 195.10.3.254
Type: Active (sending requests)
I/F: FastEthernet0/0
State: Up (Since: 2012 January Thursday 12 00:14:22 )
Clients: Fast Reroute
LSPs protecting: 1
Missed acks: 4, IP DSCP: 0x30
Refresh Interval (msec)
Configured: 50
However on the P1 router the output shows different values:
Neighbor 195.10.3.254 (router ID: 33.33.33.33) Source 195.10.3.1
Type: Active (sending requests)
I/F: FastEthernet0/0
State: Up (Since: 2012 January Wednesday 11 23:43:18 )
Clients: ReRoute
LSPs protecting: 3
Missed acks: 4, IP DSCP: 0x30
Refresh Interval (msec)
Configured: 2000
The configuration guide for IOS 12.2SR refers to active instances:
If a neighbor is unreachable when an LSP is ready to be fast rerouted, an active Hello instance is needed. Create an active Hello instance for each neighbor with at least one LSP in this state.
and to passive instances:
Passive Hello instances respond to Hello Request messages (sending Ack messages), but do not initiate Hello Request messages and do not cause LSPs to be fast rerouted.
At this point i am not sure if i configured the RSVP Hello properly. After shuting the interface FastEthernet 0/0 on P1 down i do get the backup tunnel active and rerouted, but the convergence time is too slow. I would expect the convergence time to be 4xRSVP Hello interval which is 4x50=200ms. However, the testing revealed the convergence time to be round 2,5 seconds. My goal is to get the convergence time under 300ms.
The question is, what is the actual difference between active and passive rsvp hello session? What does the Clients statement in the sh ip rsvp hello instance detail command mean and shoud i see the same interval on both ends of the link?
If you need any other specification, i will provide any other show command outputs necessary.
Thank you for any help or clarifiation.
AdrianAdrian,
Would it be possible to post the relevant tunnel configurations from your PE routers? From what you described, I am not sure if you want to achieve an MPLS path protection, MPLS link protection (NHOP) or MPLS node protection (NNHOP) here.
Best regards,

Keynote does not support exporting with embedded Quicktime Movies
I hope this helps a few of you out before you run into this problem.
Keynote does not support export to Quicktime with any slides that contain a quicktime movie.
Created a 27 page slide show with transitions, music, narrations and 6 Quicktime movies (Actually LiveType Text scrolls)
When I attempted to export it never finishes the export cutting it short after about 20 pages.
And the pages with the movies, don't start playing.
It exports fine as a quicktime movie without the movies inserted though.
Spoke with Apple Support and they confirmed that quicktime placed files within Keynote playback is only supported from the native Keynote Application.
I read somewhere on this board that it was an issue with Quicktime version 7.5, not so as I tried the same test on a mac with Quicktime 7.42 and it had the same issue.
So, beware.
LJSMaybe I didn't understand well what you said but it is possible to export a Keynote file with embedded Quicktime movies to a quicktime movie. Actually, I'm doing it and I works. BUT, the issue I get is that I can't get my embedded videos to loop. Grrr...
