I don't think there is much to think about this particular question and the extra configuration added. Whoever was solving the lab, thought that using 802.1q over ISL was a better idea. Since not specified nor restricted in the lab, it falls under "grading doesn't care about this" category.
While technically speaking it IS an extra and unnecessary configuration, it's not the one you should dwell upon. -- Marko Milivojevic - CCIE #18427 Senior Technical Instructor - IPexpert FREE CCIE training: http://bit.ly/vLecture Mailto: [email protected] Telephone: +1.810.326.1444 Web: http://www.ipexpert.com/ On Mon, Apr 4, 2011 at 07:02, marc abel <[email protected]> wrote: > I understand that, this is just a case where it seems like they > applied extra config for reasons that are unclear to me.If a question > doesn't seem to ask for something, I don't want to apply extra config. > I am just wondering if there is maybe a later dependency that I just > can't see. > > It would be nice to have one of our experts weigh in on this topic. > They seem to be quieter than usual lately. > > On Mon, Apr 4, 2011 at 8:37 AM, Jason Maynard <[email protected]> wrote: >> Hey Marc, >> Don't forget that there are at times more than one way to meet the >> requirements.
