i understand vlans. but how is a vlan network interface different from a
normal eth interface as far as higher layer protocols are concerned? or
for that matter of fact how is this different from even l2 perspective.
only difference is the broadcast domain. right ?
also, if somebody can give me an example of ifconfig output for vlan
interface, that will be helpful.
thanks.

i have been following this post rather keenly. it now seems to have died
down. but still i am not able to understand what is a vlan interface.
can somebody please give me some pointer where i can read about this.
vlan i thought is a l2 concept and should have nothing to do with l3.
http://en.wikipedia.org/wiki/Vlan might be a good start.
While VLANs are basically a layer 2 concept, you somehow need to reach
them from upper layers. This is accomplished by having "virtual
interfaces" which are "connected" to the VLAN and feel just like a
physical interface on a physical LAN from the software side.
