Administrative Distance Vs. The Longest Prefix Match

Administrative Distance – Remember that each network can run, and likely will be running, multiple different routing protocols: OSPF, EIGRP, RIP, RIPV2, IGP, BGP, and IS-IS being the most commonly used, or at least the ones you’ll need to be somewhat familiar with for the CCNA. You’ll spend most of your time learning about OSPF,Continue reading “Administrative Distance Vs. The Longest Prefix Match”

VLAN and Trunking Concepts, Protocols, and Configuration
