Hi,

I figured-out my previous problem by myself i.e Static Tunnel creation.

Can you tell me that for forwarding un-labeled packets do we need to 
configure something on Linux box ? like instead of gen:16:0 gen:0:0 or 
anything like that which forwards the un-labeled packets ?

Please clarify.

Thanks
Sunil
