Join Chris Bryant for an in-depth discussion in this video Testing and troubleshooting with pings and traces, part of CCNP Troubleshooting (300-135) Cert Prep.
- [Instructor] We're picking up…right where we left off on the last video where router two…could not ping either of the addresses on router three,…whether it's the loop-back…or router three's interface on the fast ethernet segment,…220.127.116.11 but it could ping 18.104.22.168…which is router one's interface on that same subnet.…So, also of course, if you get this unrecognized host…or address or protocol not running,…it's 'cause you pinged what I like to call IP version three,…which is where you put three octets…and then you forgot to put the fourth one.…
So let's take a look at what we're going to do now because…you know, pings are great,…they're a great starting point for your troubleshooting,…but they don't give you a ton of information…it's almost like a yes/no return.…You get some other characters once in a while,…but most of your ping returns are either going to be…time outs, they're going to be periods,…or they're going to be exclamation points.…What I want to do now is run a trace route…and see exactly where the problem is,…
