CCNP: multi layer switching
Hi Everyone,
I hope you are having a nice day. I think I need troubleshooting guidance or I am missing a piece of the puzzle.
I am trying to set up a 3550 switch in my lab. My home Internet is a 192. net and connects to fa0/1. My desktop computer is a 172. net and attached to fa0/2. My desktop can ping the 3550s 192, but it can't ping my houses 192 gateway. This is something I fought with for while. Must the interfaces have ip's or are the vlan ip's enough?
Any guidance is appreciated.
Thanks!

Try --
ping 8.8.8.8 source Fa0/2
Security: CCNA [ ]
Virtualization: VCA-DCV [ ]
I don't think fa0/2 is a routed interface but I get your drift. When testing connectivity, also check the return traffic and I guess this is the issue here, as also mentioned by the other ones in this topic.

It needs to know how to get back to where you are pinging from (this is Routing 101). Essentially what you are doing is sending a request to the home router to respond. If it does not know how to send it back then this is where your failure will occur. A good way to troubleshoot this is trace it too. Where does the trace end? If the home router does not know how to route traffic back then I would image you will find the trace to end 1 hop before it reaches your home router (i.e. your 3550 switch).
