Hi Raj,
Practically there is nothing like l3 vlans. Vlans are always l2 which breaks broadcast domain at layer 2.
Now when we create logical interface at layer 3 switches for those vlans, they are created at upper layer (ip layer) so in common terms everyone say it as layer 3 vlans. But they are just logical interfaces for those layer 2 vlans which make communication possible between vlans.

Hi Ankur,
Thanks for your reply .
I there any document specifying the difference
beacuse if we create a vlan for eg ASA then it cannot route traffic between vlans.
I want to know the diffrence as in for theory purpose only
