This post wraps up the #CCNA Q&A focused on how routers add routes to their routing tables. What happens when a router happens to learn three separate routes for the same subnet ID – but with different masks? And how
This latest #CCNA question takes us in the same direction as the previous question: how does a router choose between different competing routes? Today’s question adds connected routes to the mix, along with routes learn by routing protocols. Enjoy! Previous
What happens when a router happens to learn three separate routes for the same subnet ID – but with different masks, and with different routing protocols? What should you be thinking about when predicting how a router acts? These questions
#CCNA study scenarios often focus on the most common and most obvious combinations of events. However, sometimes it helps to think about some more unusual scenarios just for the purpose of exercising our understanding of how these devices think. This
The previous post changed the OSPF Hello interval (timer) on a WAN serial link. What’s that do to the output of various OSPF commands in our familiar router triangle? What happens to show ip ospf neighbor? Show ip ospf interface
