That's why my sed scripts ignore router-to-switch connections, I use a 3750
breakout switch and a set of 4 lab switches. It's the only way to get full
functionality with a Dynamips lab.

In early testing of the setup I used all 3550s and it works, you just won't
get CDP both ways if you're using the QinQ/breakout switch method, and you
lose all the 3560-specific features.

3550s usually run US$75-85 on eBay, which is pretty reasonable in my
opinion.

Hi John,

I don't know if you're aware of it but another option is to look at using
real switches with dynamips/GNS3.  Tentatively you could get by with 4 x
3550s which support a reasonable amount of feature parity with the 3560
(but missing out on QoS, private VLAN and I think IPv6) which are
relatively inexpensive to acquire on ebay these days.  You will either need
to have a lot of physical interfaces representing each router interface
connecting to a switch (using multiple 4 Port Ethernet NICs or a bunch of
USB NICs), or you can look at using another switch using dot1q tunnelling
to act as a breakout switch.

There are a number of blogs that work document how to do this, and it's
what I used for my home lab (though I did have some 3750s which are pretty
much stackable 3560s)

Tentatively while you need 4 switches (plus possibly another as a breakout
switch) only two need to be a 3560/3750 since most of the workbook labs
that rely on 3560 specific functionality occur on Cat1/Cat2  meaning Cat3/4
can be lower cost 3550s.

Cheers,
Adam
