[f-nsp] Transparent VLL through XMR and J-6350

[David Ball]

  Foundry has a slightly different take on making a service
'transparent' (at least from what I was used to with JNPR).  To make
it transparent, you change the tag-type to something that won't be
used by the customer (Foundry TAC recommended 9100) and then make the
port untagged in the VLL definition.  So in your config below, looks
like you should just need to set 'tag-type 9100 ethe 1/20' and be on
your way.
  I believe the tag-type 9100 is related to a Metro Ethernet Forum
recommendation regarding how QinQ should be handled (per 802.3ad).
  I was able to get this working using XMR4 and a T640, so hopefully
your J-series acts the same.

HTH,

David
