I would like to echo the thoughts of many in this thread that a concise list of PowerShell commands to study for the exam would be very helpful. Even if you cannot teach a whole class on it, just a list of the commands across each of the 70-4xx courses would make it a lot easier to study for the exams.
I would point you to the course request list in our courses section of the itpro.tv website. This will ensure that the request is logged officially. If we have enough demand for it, we will either do it or find an external SME to come in for us to do so but it requires some demand to make it happen. That is where you can make it happen!
It made no sense what was missing until I started going through the book on BGP configurations and figuring what was missing. eBGP-multihop is usually the culprit for pings not working. It was putting the network x.x.x.x mask y.y.y.y statements that got it working. BGP configuration with address-family ipv6 and ipv4 break everything up so that it would be easy to miss.
Here is the link for VRF using OSPF. This simulation is VRF for departments using OSPF. I have setup HR and ACCT to be separated. I also setup the routes to get out to my TFTP server, my workstation. Sh run | redirect tftp://192.168.1.240/iosv1_ShRun.txt so I could send the files below to my workstation.
Thanks for writing in. We have not been able to recreate your issue. That doesn't mean there isn't a problem, it just means it is a tricky one. Could I get a little more information from you? What model Roku are you using? Also, what type of internet connection are you using (DSL, cable, etc)? Last thing, what country are you watching from?
That will help us run a few more tests to see if we can narrow down your problem. My theory is that there is an issue with one of our CDN points and it is affecting you, but not us.
I don't know of a way to open the VPN dialog box. That might need to be done in C, C++, or C#, I don't think you can with PowerShell.
You might look into ras.h. I am not familiar with C programming, but that header contains the APIs to work with VPN connections in Windows.
I'm not sure what is causing the error, you will need to examine the log files. Maybe an issue during the main mode negotiation? Password mismatch? Possibly some of the encryption choices (AuthenticationTransformConstants, IntegrityCheckMethod, etc) don't match the receiving end.
