Re: Dot1q tunneling

It will be my understanding that the exercise require you to configure
the "switchport mode dot1q-tunnel" and assign it to the proper VLAN with
"switchport access vlan <vlan-id>". Now, in order to have R3 and SW2
seen each other over CDP you will need also to do "l2protocol-tunnel
cdp" as minimum.

The other part, I found the same discrepancy with the presented
solution.
