Amazing

[@kukaichou9775]

Hello Professor!
On your Port Aggregation Slide near the end of the video. Could there be a possibility that a loop is created if there are two connections on the switch that lead to the same web server? Or does that only happen when you daisy chain switches?
Thank you for all your work!

[@professormesser]

The connection is configured as port aggregation on both sides, so the server and switch will not bridge traffic between those links.

[@pkdchoy]

Are the connections between the primary device and the redundant device (firewall with firewall, router with router, switch with switch) in slide 6 and 7 for health checking purpose?

[@professormesser]

They're active network links that can be used if another link fails.

The load balancer would be the single point of failure in that scenario. Can you HA a load balancer?
