It is recommended that you DO tag the native VLAN. Otherwise, untagged
packets may become "confused" with the access vlan that your SP is using and
things may not work the way you want them to.
So while you may find in your lab you have some basic connectivity the way
you expect, as you start doing more and more things (or your SP connects
more and more devices) the behavior may change.
I believe this is listed as part of Cisco's recommendations or requirements.

Subject: vlan dot1q tag native
Hi there,
I am redoing the internetwork expert labs for R/S (IEWB VOL2 ver 4.1), and I
have seen that in task 1.5 of lab 8 the have configured dot1q tunneling, for
connectivity between R2 and R6 (tunneling for vlan 26), and they have added
the command "vlan dot1q tag native" to the solution, but I have configured
the tunneling ewithout it, and seems to work well (I have connectivity
between R2 and R6).
Do you know if it4s necessary to configure the tag for the native vlan to
configure this ? and why it is ?
Thanks in advance,
Julio.
