The main purpose of dot1q-tunneling is transparency, if you are doing any
configuration related to Dot1q Tunnel either on R1 or CAT2 then it defeats
the purpose and transparency will be lost.
The correct scenario should be the one in which no configuration changes are
required either on R1 and Cat2, they should not know the presence of Cat1
Switch in between.
The Tunnel will start and end only on CAT1. The Start Point will be the Port
on which R1 is connecting and End-Point will be the port on which CAT2 is
connecting.
