Ok, who really knows their networking?

Hey guys, looking for some input here. I have a networking project that is 99% done, so please do not think I am asking you guys to do my project, it is much larger then this question.

Anyway, this one question is holding me from finishing, I cannot find a solid answer. Any input would be appreciated.

Question: Why would the spanning tree mechanism be difficult or impossible to implement for repeaters?

I am thinking because repeaters do nothing but regenerate signals and send them back out. There is no routing or fowarding tables involved with repeaters.

I'm not following how the term "repeater" is in there, unless you're using that term to mean hubs? (which generally aren't managed, therefore don't support Q VLans, etc)

Yes, reperater or hub.

If your network uses CAT 5.. be it 10baseT, 100baseT or 1000baseT...
and your network goes pass the 100 Meter mark in length.. you have to use a repeater to regenerate the signal..

I just (very quickly) read about the spanning tree mechanism protocol..
and it mentions several times about using a "bridge".. which , in turn, links two network segments.... kind of what a hub or repeater would do..
I think this might be what you are looking for..

Much appreciated

CoolJ,

YeOldeStonecat is on the right track. Hubs do not support the spanning tree protocol and there for can cannot participate in anything that spanning-tree does. i.e root selection, layer 2 loop protection, vlan segrigation etc...

Yeah the little I've read about spanning tree, I picture it as a method of trunking VLans across switches similar using .Q. I haven't done any .Q trunking, only had the need for port based VLans.
