Hi James,

Thanks, I have already subscribed to the mpls-linux-general mailing list and 
trying to get the info from there as well.

I am trying to establish a Static Tunnel between LER A and LER A without any 
RSVP-TE or CR-LDP.

I am able to receive MPLS labeled packets on Linux box through Ethereal with 
correct sequence and TTL ,and my question is , do I need to do some other 
configurations on LIunx box(LSR) to establish a tunnel or multiple tunnel in 
addition of establishing an LSP ?

I have configure my MPLS linux box as under;


mplsadm -v -L eth1:0
mplsadm -v -L eth2:0
mplsadm -A -B -I gen:16:0 -O gen:16:eth1:ipv4:172.16.10.2
mplsadm -A -B -I gen:17:0 -O hen:17:eth2:ipv4:172.17.10.2

I believe above will establish an LSP between LER A and LER B.

Or what would be the mplsadm commands for creating a tunnel or multiple 
tunnels between an LERA and LERA through one LSR or multiple LSRs ?

Is there any good source to learn the mplsadm command scripts ? as even on 
Sourceforge the material is not sufficient enough for a new comer to 
understand and configure MPLS-Linux properly.

Please respond.I will appreciate your help.

Thanks
Sunil
