Vlan Trunking

Guys i have a quick but simple question on this topic. For some reason i'm suddenly hung up on it. I know when passing traffic between two different VLAN's you need at least a Router. Obvisoulsy they are on different subnets. Now what about if i have to switchs. I have VLAN 1 on both Switch 1 and Switch 2 and need to send a broadcast. Does the traffic need to pass through a router since they are on the same VLAN? Or is that what the VLAN Trunk is for and it the traffic goes between both switches?

Thanks for your help.

No, you only need a router if you're traversing different subnets. You can trunk two switches and pass traffic between them without a router so long as you never leave the same subnet (which means no inter-vlan traffic).

Just set the two trunked switchports to trunking mode and do a no shut, it's as easy as that.

Sweet thanks man. I had a feeling that was the answer but for some reason i woke up doubting myself..to much studying the last few days.

I know the feeling

If you have the same VLANs on both switches, you can also connect a crossover cable via an access port on both switches (in the same VLAN) to allow communication across both switches in the connected VLAN. Obviously, the trunk method is a better solution, as you only need one trunk link for all the VLANs, and not a cable for each one.

cool. Thanks Man. Makes more sense.
