Exactly patrick! absolutely agree with you! as your solution is the same
as my last and third option:
"So, as a final solution to try to satisfy all what is answered without
violating any requirement, I think, that I must create an etherchanneling of
fastethernet 0/16, with a group different than the etherchanneling of
fastethernet 0/17 at both switches SW1 AND SW2. and in SW3 to l2 tunnel the
lacp right??
Please if someone agrees with my last result or has any other ideas, you are
welcome!
Thanks!!!
