Well I don’t like the fact that your Po1–po3 po1-po4 connection is messy, I’m sure it’s supposed to be po1-po1 po3-po3 etc. Why configure the l2 tunnel? Are SW3 and SW4 supposed to see each other as cdp neighbors? You don’t tell us what the task is, but I don’t think being able to ping shows that you’ve accomplished it. Maybe they have you configuring l2 tunnels for no reason, in which case I’m clueless.
