The new mock labs are indeed done with all materials on screen. At some point – we will create a flash based interface to mimic that of the lab I suppose.

Hi Mohammad – we had to correct the network command they tried to use. They used the “classful” network command of 10.0.0.0/8, but the underlying prefixes are of /24, so we need to advertise one of them using the proper mask in order for the aggregate to work.

I had to go and see if those were real cities in PA:

Even funnier that places exist. You know what would be even funnier? If Scott pulled this out of his Butte, Montana.

Too funny.

Thanks Anthony for another good example the troubleshooting thought/flow process. Sadly, Scott is correct. I live about 20 minutes from all those funny towns in PA. He did forget to mention one of them, Climax PA.

hi Anthony,
Why did you use /24 mask in the bgp network command?
Thanks

Hi Anthony,

This is good methodology to solve the trouble ticket. Please teach us more for the rest tickets, as well as the 4 switch troubleshoot tickets.

BTW: I failed the lab on 10/27/09 due to limited resource for lab prep by myself. I now joined INE R&S 2.0 program. I think I will be fine for the next lab attempt. Please help me.

Thanks
Dengming

Yeah, Scott is serious about those towns. I live about an hour from most of them. There are all outside of Philadelphia in PA Dutch Country near Lancaster. He left off Smoketown. Cheech and Chong hang out there sometimes

Until now, every one get failed. And every one is saying same that even reading troubleshooting twice should be considered a wastage of time.
Same goes with config section, few have drawn their own topologies and at the end they have to regret their decision to do so.
I am not saying your approach is bad, but we should know what is right direction to go with V4.
Are you going to release mock interface for V4

Excellent question Nadeem! Just like in the Configuration section – you should draw your own diagram when it is needed. Some Trouble Tickets I would not be able to solve without my own diagram – some will not need one.
