Cisco CCNA Certification Training - VLANs

ICND2 (CCNA) Review - The Operation of STP

StormWind.com Cisco Mentor Question Spotlight – Collision Domains

"A question I have from the ICND1.  Can you have collision domains beyond the switch?  What if we had 2 routers connected, with switches hanging off them, and PC's connected to the switches.  I'd never thought beyond the switch, and I can't justify my answer.  The more I think about it, the worse it gets.  You're only concerned about collision domains up to the switch, right?"

 

Thanks so much for the awesome question!
