At my YouTube channel, it's Spanning Tree for the next few weeks... once I get to it. :-) A nasty bug kept me away for over a week, so no new video this week! But I'll be back next Wednesday with a new video digging into STP convergence (with review of course), with more STP the following week. In the meantime, if you want to brush up on the basics of STP, check out this video on the basics of STP (applies to RSTP as well), plus two Interview Review videos to practice your skills!

Today’s lab: Extended IPv4 ACLs
🔒 PC0 & PC2 blocked from using DNS on Server1
🔓 Only PC0 can reach 192.168.15.0/24, PC1 can’t.
📊 Result: PC0/PC2 can ping by IP, not by name. PC3 can ping PC0, but fails to ping PC1 (blocked).

@artofneteng As always, this episode was very insightful

Today’s lab: Standard IPv4 ACLs
1. Configured standard numbered ACLs on OSPF routers (each also a DHCP server).
2. Simulated 4 remote departments.
✅ QA → Tech only
✅ Sales PC0 blocked from Marketing & QA.
📊 Added deny any to log all denied traffic.

Agentic A.I. is one of the newest focuses we’ve been seeing in the industry & more so recently at @CiscoLive ! So what’s the difference between Agentic & Traditional A.I?

For the next two weeks, I'll post videos completing the topics from the CCNA OCG Vol 1 Chapter 7, which is all about LAN Switch interfaces. I'll post three new videos this week and three more next week. If you want to get started now with what's already posted for that chapter, check out this video about the first topic in the chapter: Ethernet Auto-Negotiation.

Wednesday starts with another automatic process: Automatic pinout adjustments with Auto-MDIX. More soon!
