11. Administrative Distance

Master administrative distance — one of the most important and most tested concepts in CCNA routing! This video explains exactly how routers use administrative distance to choose between competing routes from different sources! In this video, you'll learn: - What administrative distance is and why routers need it - How administrative distance ranks the trustworthiness of different routing sources - The administrative distance values for every major routing source — connected, static, EIGRP, OSPF, RIP, and more - How a router chooses between two routes to the same destination from different sources - What happens when two routes have the same administrative distance - How floating static routes use a higher administrative distance to act as a backup - How administrative distance differs from a routing metric - How to verify administrative distance values in the routing table - How to modify the default administrative distance of a static route or routing protocol Administrative distance is the tiebreaker between routing sources — and getting it wrong means traffic takes an unexpected path. This video makes sure you know every default value, understand how the selection process works, and can apply that knowledge to any routing scenario on the CCNA exam. #systemengineer7131 #CCNA #Ping #ICMP #NetworkTroubleshooting #ExtendedPing #CiscoNetworking #CCNABoost #NetworkingTutorial #CCNA2026
