What about the differences between DEC and IBM bridging and the good old Lou Rossi paper? Is this all filtering into 802.1D somehow or was that a TR bridging thing that was nothing to do with STP? Seems a long time ago now.

There is MISTP (802.1s) as well or is that MST?

One one side, it's a collection of stupid trivia. On the other side, it's
knowledge of history which sometimes explains how we got where we are at and
can help predict where we may go next! it's all about the experience level!


CSTP or CST is Common Spanning Tree. Historically:

802.1D which was one spanning tree for any/all networks came first.
PVST was created next by Cisco for doing separate STP per VLAN.
802.1Q came next as a trunking algorithm, but here is where CST was put in
the spec just to piss Cisco off.
PVST+ was the workaround to this by simply changing the multicast MAC
address used to "sorta tunnel" STP frames in separate VLANs.
MST came next where the industry finally (partially) agreed with multiple
instances of spanning tree, and RSTP came along with it.
Rapid-PVST came last where Cisco said "that's cool!"

HTH,

Scott

PS.  Most people wouldn't know this unless they really had to teach it or
explain it to people on a routine basis!

Ok, out of curiosity, I know of STP evolution from STP>MSTP>RSTP with
Cisco's version of PVSTP>PVSTP+

Which RFC defines CSTP?

Also, I googled CSTP and the first thing that came up is CSTP - Certified
Security Testing Professional.

If this is correct, then it's pathetic that someone's years of career can be
judged by these moronautic interviewers! Another reason why people set up
their own business, I think. Phew!


Many Thanks

Doh!

I hate such interviews, it's not as if I want to be a researcher in one of
the MIT labs, is it?

A Customer wouldn't ask me what the 2 most unused flags in TCP is, will
they?

Ok, maybe google needs lab engineers, or researchers or something, because I
don't get? As a specialist for few years now, all that is required of me is
to design according to customer's specification and provide 3rd line support
when things are going A-wire!


What do you guys think?

Many Thanks

Yemi Salau

Hello All,

I was surprised to see the thread resurrected again. I did take the
interview a couple of weeks ago. Didnt get through although i felt I did
well.
Like most
of you had mentioned, there was a hint that the package wouldnt be all that
great.


Although there was network trivia like the working of a traceroute.
There was
a few pretty in depth questions, like what are the two most unused flags in
TCP. They also asked about CSPF about which i had no idea.


Cheers,

Calvino
