I think I am not fully understanding the question completely, but if you
needed to do an etherchannel between SW1 and Sw4, you would just need
completely and transparently tunnels channel protocol across SW2 and SW3
and you could just use dot1q tunnel for it and if you configure channel
as on SW1 and SW4, you could probably make it work without tunneling.
Having a split etherchannel kind of goes against the definition of
etherchannel.
Not that it helps with CCIE lab or anything but in the future besides
stacking of say 3750s, 6500 will have a feature where you could turn two
switches into one virtual switch. I think it should be available
sometime in 2007 and hopefully will not have too many IOS bugs. :) I am
actually checking with our SE on a presentation on the new features
coming up.

Subject: Re: L2 etherchannel between 2 differents catalyst
This is my first thought, but my final point would be config a new SW4
with l2etherchannel (2 fastethernet) to SW3 (1 fastethernet) and to SW4
(1 fastethernet), in others words, config a etherchannel multichassis
between
SW1 and SW2 with IP connectivity.
* SW2 *
* *
* *
SW1 * * SW4
* *
* *
* SW3 *
Thanks for yours inputs,
Matt.
