Newbie here, big question

Hi yawl !,

I have an assignemnet for Uni. It's a case study. the question gives three
swtiches hanging off a router in a three router scenario. eg on in sydney,
one in melb and one in brisbane.

I'm given a class C public subnet of 233.0.0.0 for internal address.
I'm expected to subnet this . Might be a basic question but in subnetting do
I regard the switches as a router (sort of) when calcualtin nubers of hosts
.. . (do you know what I mean - do the switches and their hosts each become a
subnet to calucate ????)
I'm Confused.
TIA,
Anthony

Me too - this group has "home-networking" in the title - how many home
networks do you think use subnetting? When I was at University we had
these invaluable aids to learning called "books", which they kept in a
thing called a "library" - if we wanted to find out about something we
would go there and "read" them.

Class C subnet written to look like a class A..... very clever.
You gotta take it back to binary, to work out the subnets easily
Calculating each switch as a subnet would be easiest, although is a
strange setup for your example, would expect routers.
don't forget to give the router an address in each subnet too tho,
otherwise you'll struggle to get it working
Good luck with it.

I agree with Rob's opinion about spoon feeding. If you can't find this out
yourself, you will never succeed.

I will give you a clue or two, to help you find things out.

A switch is not a router.

A switch is layer 2, a router is layer 3.

There's a neat perl script called ipcalc which does subnet calculation for
you.

Rob mentions libraries, as in buildings full of books as opposed to
collections of commonly used subroutines. It was the same when I was at
University. They are indeed very useful. Nowadays, we also have an
Internet. It is not a write only medium. You guys are spoiled, really. As
we were compared to the previous generation, etc.

Some of the best books were written by W.R.Stevens.

Windows is not an ideal platform for network experimentation. Try Linux.

Correct spelling enhances communication.

thatnk you for your reply. I realise it's a home network NG but I couldn't
see any other NG's that might fit the bill.
Cheers,
yeah it is a class A.

You too, need an enema.

Why, will that stop clueless twats from polluting newsgroups with
irrelevant crap?

Check your definition of Class A :-) (or take NuTTeR's advice and
convert it to binary - hint: Class A binary addresses start with 0)

These "real" things are commonly known as 'life'! So, if it sounds
sarcastic, don't take it seriously. If it sounds hazardous, Do not try
this at home or at all. And if it offends you, just don't read it.

In that case its fairly easy to do the lazy way.
233.0.x.x for the backbone
233.1.x.x for site 1
233.2.x.x for site 2
etc.
Subnets would be 255.255.0.0 unless you have any reason to subdivide
further at a site level, but you still have enough addresses for a every
dept to have a class C subnet.
