hi fewi

i have my noobish question since i have no network certificate or proper training but im learning with my own self readings some forums etc etc now my question is how to communicate VLAN1 to VLAN2 ?? or need to bridge both vlans?? as my understanding VLAN can segregates broadcast domains .

thanks

if you want both vlans into the same broadcast domain then, yes, bridge them together.

wow thanks mrz for information u share

But don't bridge unless you have to. When in doubt, route.

VLANs are just like physical networks, only they can exist on the same wire.

Read that, and if you don't understand it, click on all the links to learn about the terms used to explain the concept of a VLAN.

So to communicate on layer 3 between two VLANs you have the router route between the VLAN interfaces, which it will do just fine and out of the box. They appear as normal interfaces, and the router doesn't care that they are not physical. They are incredibly useful and it's worth spending the time learning how they work. Once you understand them and have gear that can use them it's trivial to split all management traffic off from customer traffic, for example, and prevent that customers can even see a login page to your AP - even when you just have one single wireless or wire link to a specific location.

VLAN 1 is also the default VLAN on a lot gear and you'll want to avoid using it if you're trying to separate traffic. VLANs can work different ways as well. They can be internal to a piece of equipment and used to separate ports on a switch and not tag any traffic leaving an interface or you can set equipment to tag packets leaving an interface to extend the VLAN across to different pieces of equipment. In Cisco terminology it's referred to as access ports and trunking ports.

If you want to learn networking I'd suggest getting Cisco's ICND 1 and ICND 2 books. A Safari Online account will get you access to the full library of Cisco material. You may not work with Cisco equipment but they're the standard for network training and certification that everyone recognizes.
