[j-nsp] M120 lt (Logical Tunnel) interface

[Mauritz Lewies]

Hi 

Thanks for the mail. 
Yeah I've found that as well, but there were some threads where guys stated you can do the same with a MS-PIC. However it doesn't work...

I'll look into your suggestion about the sp- interface. You wouldn't by any chance have any docs / links on the topic?
