question eBGP and iBGP
Hey guys,.
I have a problem with this topology, I'm new to BGP so I will try to understand.
(R1)
IP route 192.168.2.2 255.255.255.255 209.165.202.130
router bgp 65100
The log-neighbor BGP-changes
209.165.200.224 netmask 255.255.255.224
192.168.2.2 neighbor remote - as 65000
neighbor 192.168.2.2 ebgp-multihop 255
neighbor update-source Loopback0 192.168.2.2
(R2)
IP route 209.165.201.1 255.255.255.255 209.165.202.129
router bgp 65000
The log-neighbor BGP-changes
network 192.168.22.0
192.168.3.3 neighbor remote - as 65000
192.168.3.3 neighbor update-source Loopback0
192.168.3.3 neighbor next-hop-self
neighbour 209.165.201.1 distance - as 65100
neighbor 209.165.201.1 ebgp-multihop 255
neighbor 209.165.201.1 update-source Loopback0
(R3)
router bgp 65000
The log-neighbor BGP-changes
network 192.168.33.0
192.168.2.2 neighbor remote - as 65000
neighbor update-source Loopback0 192.168.2.2
The thing I don't understand is that R1 and R2 can ping each other but R1 and R3 can
The R1 and R3 have entered into the table to the other bgp, but not ping between them.
Can someone explain why?
Good morning Martine.
I check that you lack some configurations as below
R2:
IP road 192.168.3.3 255.255.255.255 172.16.23.3
R3:
IP route 192.168.2.2 255.255.255.255 172.16.23.2
Why you use the static route for your wan link. You must use the default route for WAN link on the Router R2.
Don't worry, if you want to keep the same configuration that you have used then Source Loopback interface 1 when the ping command:
Example:
R1 #ping 192.168.33.1 source loopback 1
Kind regards

I have a subscription valid and active Leica camera.
How can I get Adobe to recognize? My creative cloud has expired. I'm frozen out of my photo library
Using the redemption code Leica I downloaded successfully updated day to day LR 6 but my LR library for 2015 and beyond now has a question mark, and I can't open the images.
Any suggestions?
Is this something that Adobe has to rectify?
Thank you
John
The question mark has nothing to do with your subscription at the end. The question mark on your records indicates that Lightroom cannot find the photos, because they have been moved or renamed, or delete outside of Lightroom. The instructions to fix it are: Adobe Lightroom - find folders and files moved or missing

Hello community,
I have a following question design and update on vSphere 6 with MRS.
In out of our subsidiaries, we have configured following installation:-VMware vSphere 5.5 environment with Site Recovery Manager that runs on 5.8 installed U3.
-Two vCenter server running in a configuration in linked mode, so you only need access to a vCenter server to see both sides.No, we want to upgrade to vSphere 6 and here I have some question how says it in the best conditions.
Wouldn't be a good thing or maybe it's mandatory to have a service of external platform controller installed in the vSphere environment and then start the upgrade to vSphere 6 each side has its 'own' PSC.Thanks for some tips and training on your side.
Did you read the documentation regarding the upgrade to SRM 6 located here: Site Recovery Manager 6.0 Documentation Center
Who will answer all you questions, including your subject to PSC. A short summary, you want a PSC for each site. The reason is that you want that each site to be completely independent of the other.
If read you the docs and you still have questions, please post them.

-IF not, Details of the message from the error messages and a person may be able to help (just not Adobe)

I opened my garageband, but I does not, because there was a question mark hollow garageband icon, then I restarted the computer, it normally restarted (whithout saying I restarted the computer because of a problem), and when it was made of built-in apps were question marks, were not in the program and "it is not found on the computer.
Please help even the app store is broken and he asked me if I would choose a program from the app store when I tried to re - download from the internet, said yes and it did not work. Help, please
The? means that the location for the file specified in the Dock cannot be found.
You said "were not in the programs.
Did you mean that they are not located in the Applications folder? Windows has a record of programs, not OSX.
You said "when I tried to re - download from the internet, said yes and it did not work."?
What happened when you tried?
The missing applications are in the purchase of the Mac App Store section?

The https://support.mozilla.org/questions/959992
This has already been done, but he still plays for some downloads of mp3, mp3 instead of ask me where to save the file.
Is there a way to fix this?Ah yes, I remember now.
From 26 of Firefox, Firefox can also use DirectShow to play MP3s natively in the browser. This added support for Windows XP handle the MPEG encoded media. So you will also need to disable this, too. I'll add that as step 4:
(1) in a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful.
(2) in the filter box, type or paste media and make a pause so that the list is filtered
(3) double-click on media.windows - media - foundation.enabled to change its value from true to false.
(4) double click on media.directshow.enabled to change its value from true to false.

Hard drive replacement and warranty question Portege and Tecra models
Good afternoon
I'm hoping for a little clarity if a laptop warranty is invalidated if the hard drive is replaced for another title of model/difference. The company that I work buys models Tecra and Portege for these last years, if we decide to buy more large hard disks and get our IT Department install them will be that gap in the agreement of guarantee with Toshiba?
I talked to Toshiba and they were a little gray in their response. They said that, if you didn't damage the laptop, it should be fine, but if you send it as an unrelated question, with what they can carry out repairs on the laptop if the hard drive does not match the orgional one provided...
Can somone if this is the case? It seems ridiculous that you would not be able to replace the drive even if bought from an official and used dealer in a corporate environment.
Kind regards
Jonsey
As much as I know RAM and HDD upgrade do not negate the warranty. For many models of laptops, you can find instruction how to do this. It is described in the document of the user s manual or you can find short videos on Toshiba documents (knowledge base).
Even on this forum in the USER SELF REPLACEMENT section you will find instructions how to replace the hard drives.
What you can also do is to contact the nearest Toshiba authorized service provider and check what they say on this subject.

iCloud question library and roll camera
If I turn on iCloud library on my Mac and my iPhone, all existing photos in iPhone camera will roll and photo streams appear in pictures of my Mac?
And the existing camera roll photos will be downloaded on my Mac if I download original activated on my Mac?
The reason I ask this is pictures of my Mac is my master library of photos I want to keep. I could take 10 photos with my iPhone of a scene, but only to copy one of these ten photos to pictures of my Mac and I let all ten photos in the Filmstrip of the iPhone. I'm afraid that when I turn on iCloud photo library on my iPhone, I'll pollute my Mac with photos Photos, I don't want to keep.
With this in mind, would you recommend that empty of my film and photo stream iPhone before I have activate iCloud photo library on my iPhone?
Thank you!
These articles support should help to answer your questions, but in general, all the photos from all sources will download to iCloud photo library if you have enabled it, as all changes and deletions will load:
