mesh...

this is a meshed network...

ether channel links all the way around, 2 ports each, how to label them...

this speaks to design, comfort, logic, economy and sanity...

how i would label them (knowing full well that the etherchannel numbers are only locally significant)

dls1 --> als1  1 to 1 (counter clockwise)
als1 --> als2  2 to 2
als2 --> dls2  1 to 1
dls2 --> dls1  2 to 2

dls1 --> als2  3 to 3
dls2 --> als1  3 to 3

is this correct, by the cisco book...  maybe, but who cares..

the point here is that this kind of thing, your logic, your method, is the correct method in a time pressure situation...

if you are not given specifics for the implementation, then have your own logic in place before you sit, stick to that logic... reuse that logic in practice  so you don't waste valuable time coming up with a plan...

like an ip addressing scheme... dls1 is always 172.16.1.1 and dls2 is always 172.16.1.2... or 192.168.1.1 and 1.2 unless otherwise stipulated...

and als1 is always 1.101 and als2 is always 1.102, and so on...

make things that you can, automatic...
