CCNA/CCDA/CCDP/CCNP renewal, Fort Lauderdale FL, Day 4

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
