Understanding EIGRP Metrics and Commands for CCNA Success

What command would you use to display EIGRP metrics such as hop count?

• A. show ip protocols
• B. show eigrp neighbors
• C. show ip eigrp metrics
• D. show ip route

Answer: (D)

The command that displays EIGRP metrics, including hop count, is directly related to the routing table, which is what the command "show ip route" provides. This command lists the routes known to the router, along with their associated metrics and administrative distances, allowing users to see not only the paths to various destinations but also their respective hop counts as calculated by the EIGRP protocol. The primary function of "show ip route" is to give an overview of all the routing information and statistics, which includes metrics derived from protocols such as EIGRP. Therefore, when seeking EIGRP metrics specifically regarding hop counts, the output of this command will reflect the calculated distance using EIGRP's composite metric, which includes both bandwidth and delay, along with the overall hop count as part of that information. Other options serve different purposes and do not provide the specific details about EIGRP metrics as required by the question. For instance, "show ip protocols" offers information about routing protocols in general but not detailed metrics. "Show eigrp neighbors" focuses on neighbor relationships within EIGRP, listing neighbors but not metric details. Meanwhile, "show ip eigrp metrics" isn't a valid command, which also affirms that the

When it comes to preparing for the CCNA exam, understanding EIGRP (Enhanced Interior Gateway Routing Protocol) metrics is crucial. One common question that pops up relates to which command can display these EIGRP metrics, particularly hop count. And the answer? It's the "show ip route" command. But why is this command so significant, and what exactly does it reveal? Let’s unpack that a bit.

First off, let’s clarify what EIGRP is. This protocol is like that trusted friend who's got your back in routing decisions. It chooses the best path for data packets based on various metrics, one of which is hop count. But here’s the catch—you need to access this information correctly.

So, when you type in "show ip route" in your router’s command line, what are you actually doing? You’re getting a peek into your router’s routing table. This table is like a roadmap, revealing all known routes along with their respective metrics including bandwidth, delay, and yep, you guessed it—hop count. It’s this composite metric used by EIGRP that gives you the best insight into how data will flow through your network.

Now, let’s quickly look at some of the other options you might stumble upon. For example, "show ip protocols" gives you a broader view of all routing protocols running on your router. But it doesn’t get into the nitty-gritty of metrics like hop count. Similarly, "show eigrp neighbors" is important but only tells you about neighbor relationships—who’s connected to whom without giving details on metrics.

You might even wonder about "show ip eigrp metrics." Here’s a fun fact: it’s not even a valid command! That’s right; it’s a dead end. So, if you’re pondering how to gather EIGRP metrics, stick with "show ip route."

Are you feeling confident yet? The beauty of mastering these commands is that it equips you not just to pass your exam but also to excel in real-world networking scenarios. Imagine troubleshooting a network failure—being able to quickly check your hop counts and metrics could mean the difference between a quick fix and hours spent debugging.

So, before we wrap up, remember this: knowing the right command isn't just a checkbox for your CCNA prep. It's a tool you'll carry with you into your networking journey. As you study up, keep reinforcing these commands and their functions in your mind. The "show ip route" command is your gateway to understanding how EIGRP operates in your networks—so don't overlook it!
