Logical LAN. What`s this???

[DICS]

Can anybody explain me in a word in which cases it will be usefull?
Thanks in advance.

To separate broadcast domains, i.e. to have two separate networks on one network interface.

I would use it for routing between different subnets. I don't see how it can separate broadcast domains.

Broadcast traffic will not pass between VLAN's or across routers.

It had to be in one word, but there's a lot more in it.

I think logical LAN and VLAN are different things!

A logical LAN is simply a LAN. If you have a LAN with two VLAN's, you have one Physical LAN (eg one LAN switch), but two or more logical LAN's within that physical one.

A logical lan on the IPO is nothing more than a second ip ont the same interface. This is not the same as VLAN.
In case of a vlan the ethernet frames are different and you need to configure trunking (802.1q), something the IPO doesn't support.
