Re: i want to know diff advantages of 802.1Q and ISL????

Hi,

From my experience, I appreciate ISL for InterVLAN routing possiblities : with 802.1q, I needed one Ethernet interface for each intervlan routing whereas with ISL I can configure as many sub-interfaces I want with various VLAN on each and achieve the interVLAN nice and easy!

Try to configre some InterVLAN routing and you will enjoy ISL!

Hope this somewhat helps!
