Hey Guys, I was doing a CCNA lab with intervlan Routing. The network topology is x3 switches (1 vtp server , 2 clients) x1 Router x3 End device Computers x1 Tftp server Basically i setup everything correctly , the computers on the seperate vlans can ping each other. But here's my question, should the switch be able to ping the computer's? I was not able to ping a computer from my switch. If it helps , I can upload the packet tracer file for it. Cheers

THe switch's management interface is for all intentions the same as a computer ie you should choose a VLAN that it should reside on and give it an IP and the default gateway of that VLAN.

Yeah, your layer 2 devices are not configured to be on any particular vlan. You can ping between pc's coz you have your vlan trunking to your layer 3 device configured correctly.

yeah in the absence of a multi-layer switch the router is used for inter-vlan routing, ie router on a stick. The whole point of your lab. If your distribution layer switch is layer 3 capable you don't need a separate layer 3 device. But in order to ping from a layer 2 only switch you have to assign ip addresses to the respective vlans.

I actually ended up finding what was wrong. I didnt add this command on the router. int fa0/1.99 encapsulation dot1q 99 native ip add 192.168.99.1 255.255.255.0 now everything works :)
