Yes.  In theory you should be able to do:

mplsadm2 -A -O 0 -o push:gen:16:set:eth0:ipv4:192.168.2.1
mplsadm2 -A -T mpls0
mplsadm2 -A -O 0 -o push:gen:1600:set:mpls0

But there is some broken code preventing this.  Instead you'll
have to do this:

mplsadm2 -A -O 0 -o push:gen:16:set:eth0:ipv4:192.168.2.1
(key: 0x2)
mplsadm2 -A -O 0 -o push:gen:1600:fwd:0x2
(key: 0x3)

Or alternativly:

mplsadm2 -A -O 0 -o push:gen:1600:push:gen:16:set:eth0:ipv4:192.168.2.1
