Transparent VLL between XMR and Juniper T-series

  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.

David,

 From release 3.8.00 both VLLs and VPLS instances support
dual mode  
ports (i.e. both tagged and untagged Ethernet frames),
unless you   
really want to support transparent VLANs (similar to QinQ)?

If your trying to do transparent VLANs try changing the
ethtype on  
the VLL edge port, like:

NetIron(config)# tag-type 9100 e 3/1

...and ensure the VLL edge port is untagged.

  Thanks for the great suggestions.  I tried setting the tag
type manually and things worked great for both tagged or
untagged.  
   That said, I have to think that there's a non-kludgy
(please pardon the expression) way of doing this though, no
?  I mean, how do folks deliver Transparent Lan Services to
their customers?
  I'll use the 'tag-type' workaround if I must..........but
must I ?  I've tried 'raw-mode' with untagged endpoints,
which works great for untagged, but as soon as it's tagged,
it only works in 1 direction (from Juniper to XMR, not the
other way around).  the MTU is 1500, but the test set is
generating 1280 frames, so MTU shouldn't be hindering it...

vll xmrtop-t640-vll 500 raw-mode
  vll-peer 172.16.0.1
  untag e 2/11

Try to using SAV + VLL 
  
XMR global config 
  
tag-type 9100 e 1/1 
  
router mpls 
vll test100 100 
vll-peer <juniper> 
untag e 1/1 
  
You can send traffic with any VLAN ID and XMR will
transparently switch.
