[j-nsp] Vlan Rewrite - Non IQ PICs (MX)

[Humair Ali]

HI Tarique

what type of TCC are you talking about ? VLAN -TCC ?

I guess it depends on how JKING wants to do his VLAN mapping,

from what I remember VLAN-CCC only supports one type of TPID, whereas
vlan-rewrite can support all 3 types of the TPID.

now don't ask what the 3 TPID 0x8... are as I don't remember :-p

I personnaly wasn't aware you could do vlan rewrite directly on the TCC
config, I always believed you still needed to configure the input-vlan-map
additionally to  the TCC config.

If true, then I guess we never stop learning, if not then it is added config
for nothing,

Can anyone confirm this ? thanks

Furthermore, if the choice is between the two, I would use VLAN rewrite as
it is a bit more flexibility, such as the option to have CE-PE on one end
sending native packet and tagging only on when the packet reaches the PE
interface (via native-vlan-id options) and the other end can have the vlan
being forwarded to the CE.
