[mpls-linux-general] MPLS and virtual interfaces

[Alessandro De R. <ale...@ho...>]

Hi all, I am using the MPLS kernel patch on a Fedora Core 3 distribution. 
The patch is successfully installed and it seems to work fine. I am now 
trying to use a network simulator (called NCTUns) to simulate MPLS 
forwarding but I am experiencing some problems.
NCTUns creates TUN/TAP interfaces for each node of the simulated network 
(e.g. tun1, tun2, tun3 and so on) which means "virtual" interfaces. Is it 
possible to run MPLS instructions with these interfaces?
Thanks in advance
