Hello,

(I'm also reply to the new mpls-linux-general list at sourceforge,
you should have been added, please use this list in the future)

mplsadm is just a comand line utility that gives access to the
MPLS forwarding plane API.  This API would be used by LDP
or RSVP-TE (if someone chooses to implement it, hint hint)
If you want to manually setup LSPs this is the tool to use.
If you want to dynamically setup LSPs use LDP.

I'm not sure what you mean.  Do you want to see the label stack?
Right now, I do it by hand, by using tcpdump.  Maybe ethereal
has support for it now.

I would change it to mpls-linux-0.700 linux-2.4.0-test11 and the soon
to be release ldp-portable0.065 :-)

When you say "work" what do you mean? ;-)

There is a small amount of help.  Run ldp_linux as root (hit enter
and then type ? and hit enter)

I just realize that the README for ldp_linux doesn't contain any info
how to run it.  I will write up a README and add it to ldp-portable-0.065.

For now:

Start up ldp_linux:

./ldp_linux

Add a global object:

prompt> add global 172.16.0.1

Add an interface:

prompt> add interface eth1

Show the database of sent/received labels:

prompt> show database

Show the list of established sessions:

prompt> show session

Show the list of discovered adjacencies:

prompt> show adj

That should get you started.  I will write a more complete doc.
