Here is how I do it:

on C
----
mplsadm2 -A -I gen:101:0
mplsadm2 -A -I gen:201:0
mplsadm2 -I gen:101:0 -i pop:peek

on B
----
mplsadm2 -A -O 0
mplsadm2 -O 0x2 -o push:gen:101:set:eth1:192.169.1.2
mplsadm2 -A -O 0
mplsadm2 -O 0x3 -o push:gen:201:fwd:0x2
mplsadm2 -A -I gen:200:0
mplsadm2 -B -I gen:200:0 -O 0x3
