Hey all,
Not much happening today, that I didn't make happen :(
My eyes are getting poofy again, and it is only 4 days into it. The first test is usually the killer. It is on Sunday afternoon. I have gone through 350 study questions so far in the last 4 nights. While they are great questions, they take a while to go through as you try to figure out how they got a certain answer. Sometimes it is obvious, other times you just wonder if they got it wrong.
We did a lot of layer 2 switching today, particularly Spanning Tree Protocol, root bridge selection, BPDU's, and all that jazz. I am running PVRST+ on the school network. It good. Then I learned about MST and thought, HEY! This is pretty cool! I should do that....(when I am 1000+ miles away from work). 3 hrs later I got it all configured...Ooops!
Then, about half way through this whole thing, I get to thinking, I bet the days of Layer2 switching are really numbered. I completely blew up my layer 2 stuff, yet layer 3 was working fine...hum.... Now...I can't do that with everything in my network yet, but someday I will! Layer 3 all the way down to the device. Some of you might think, "Well heck yes Tom, where have you been!" I heard about it about 8-10 years ago, but thought it was a long way off.. Time flies!
More tomorrow.
Tom
