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

[Colin Horsington]

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.
