I am not really sure (I am mostly working on the 2.6 version with a new
mplsadm and debugging mechanisms that will make it easier to track bugs),
but I wonder if the eth1 interfcace is MPLS enabled? Try setting the
labelspace (e.g. to 0) before actually mapping the traffic to the LSP

mplsadm2 -L eth1:0

before
mplsadm2 -O key1 -o push:gen:16:set:eth1:ipv4:10.120.0.6

Idem for host B

The answer to that question is complicated and out of the scope of this
mail :-P but netlink is a linux kernel mechanism that allows user space
applications to communicate with parts of the kernel (for example to
get/set routes).

It's being lazy....


Not sure if it answers your question, but it is worth trying.
