Re: Vlan to Vlan : L2TPV3 question

I am not trying to do anything by myself ..
This is example from the book " L2 VPN architectures " Chapter 11 ;
page 384 . No extra command has been used by the author .

I am trying to understand the dot1q label ; what is carried and what
is seen where ?

PS : If I am not wrong ; you are trying to mix this with a feature of
EVC where one can push/pop/translate upper 1 or upper 2 tags .. This
is a diff story !
