B means "bind", mplsadm -A -B -I gen:34:0 -O <key> means that you want to forward the packets coming with label 34 to the output with the key <key>. When you add an output (mplsadm -A -O 0) a key is returned, that is the key you have to use to refer to that output. You can see which key refers to which output in the file /proc/net/mpls_out. If you just want to recieve the packets (POP & PEEK) , do: mplsadm -A -I gen:34:0 You can see the inputs in /proc/net/mpls_in Best regards, Miguel.
