[f-nsp] Transparent VLL between XMR and Juniper T-series

[David Ball]

  Is it possible to build a transparent VLL from an XMR?  I've
successfully got a VLL running between an XMR and a Juniper, with the
XMR endpoint specified as 'untagged' and the VLL in 'raw-mode'.  If I
send untagged traffic, all is well.  As soon as I send tagged traffic,
it breaks.  Given the 'untagged' command for the XMR endpoint, I guess
I'm not surprised, but I'd ideally like to be able to receive untagged
OR tagged traffic and just send it to the far end (ie. transparent,
not caring if tagged or untagged).  I'd rather not have to
manage/maintain any VLANs that the customer may be sending us, but I'm
still trying to get my head around how it might be done (do I use
raw-mode or not?  Is the XMR endpoint untagged or tagged if I don't
want to 'care'?).  Nudges in the right direction would be appreciated.
