dot 1q encap

[gauravprakash]

HI,

I think dot1q is a L2 trunking protocol. I is used to carry traffic of variuos vlans across switch trunk ports..

So as far as L2 switch is concerned, its ok.

But with Routers we can do

#int Eth 0.1

encap dot1q <vlan_id>

ip add X X X

I cannot understand why how can we use dot1q here ( NON TRUNKING) , that too with ip address..

Plz explain..

Regards,

Gaurav

You are trunking here: you are setting the ethernet encapsulation to dot1Q. The ip address&mask are used to bind an ip range to the vlanID.
