In planning for your CCNA and CCNP examination achievements, you have got to understand to repair ’cisco’ routers. And while called ping is a fantastic primary IP connection device, it doesn’t provide you with all the details you need to identify system connection problems.
The five times indicate that there is no IP connection to CityB. Problem is, thats about all called ping claims. You can have 5 or 50 routers between the two factors, so how can you tell which downstream wireless router has the problem?
Thats where traceroute comes in. Traceroute delivers three datagrams with a Time To Stay (TTL) of 1. Those datagrams will timeout once they hit the first wireless router in the direction, and that wireless router will react with an ICMP Time Surpassed concept.
This indicates that the wireless router at 30.1.1.1 doesn’t know how to get to the ultimate location. Now you have a better concept of which wireless router has an issue!
Now this is the bad part: you’re going to get 30 collections of three asterisks, and until you abort this traceroute, you’re going to just observe those asterisks go across the display. Theres an abort series that the wireless router refers to in the first range of the system outcome, but the wireless router doesn’t tell you what it is! So I will - this top-secret series is TWICE, one right after the other.
That key stroke requires a little getting used to, but a CCNA or CCNP can do it! Add this control to your ’cisco’ expertise set, and it will provide you well both on the CCNA and CCNP examinations and your real-world systems. And you will make an impression on your buddies by understanding how to quit a traceroute!
