Today we’ll wrap up this lab (hoorah!) with a discussion of the last major task for this lab. As with tasks 1 and 2, this lab task starts with an initial config as stated back in the 3rd post for this lab. However, in this case, I tell you one change – R3 gets a [...]

Today we’ll move on to the 2nd major task for this lab. As with Task 1, we’ll start with a look at the connected routes, and then chase a few subnets around the topology to find out if the routers appear to be missing any network, auto-summary, and passive-interface commands.

This is post 5I’ll list links to the first four posts after the fold. Today’s post: I’ll wrap up the analysis of task 1, specifically chasing many of the route advertisements so reverse engineer whether the config includes the network, auto-summary, and passive-interface commands.

If you can’t predict what should be in the routing tables when you know the topology and the config (as shown in lab 3 post 1), then you’re not going to be able to predict the config based on the topology and some show command output. Today’s post completes the part of the initial part [...]

Today’s post wraps up CCENT Lab 2. I’ll likely extend this lab as lab number 3 as time goes on, because it sets up a nice discussion of auto-summary and maximum-paths. But as promised, today’s post looks at R3’s routing table, again using the configuration as shown in answer part 1, with emphasis on two [...]
