Hello Mauritz,
You need a T-PIC on M120 to have lt-* interfaces:
Logical tunnel (lt-) interfaces provide quite different services depending
on the host router:
On M Series and T Series routers, logical tunnel interfaces allow you to
connect logical systems, virtual routers, or VPN instances. The router must
be equipped with a Tunnel Services PIC or an Adaptive Services Module (only
available on M7i routers).

Having said that, I believe You can "emulate" lt-* interface unit pairs with
sp-* interface unit pairs+"match input-output allow-all" Stateful Firewall
rule to achieve same effect but I never tried that myself...

Subject: [j-nsp] M120 lt (Logical Tunnel) interface
Hi
Does anyone out there have lt- interfaces on a M120 Chassis with a MS-PIC.
Been Googling for a while and there is conflicting info between users and
techpub docs.
Users saying you need Tunnel/AS or MS-pic. Techpubs saying you need Tunnel
pic and that lt- is not supported on the MS-PIC...
Any realworld users of lt- interfaces out there?
