Hello,

I think you will have more success with the version of ldp-portable
that is in p4 (http://mpls-linux.sf.net/)

See my response to your other questions in line.

You do not _have_ to use them, but it is the "best common practice" :-)
The reason is that the default 'egress mode' is to only be egress
for the LSRs 'LSR-ID' (which is the dummy0 address if you have one).
If your LSR-ID does not show up in your routing tables as a /32 I don't
think 'LSR-ID egress mode' will work.  You can change the egress mode
to all, or interfaces and that should work.

Bugs.  Try the version in p4.

Changing the order of startup may give you differnt results.

Hmm.  I haven't seen this.  Could you file a bug at
http://sf.net/projects/mpls-linux?

> - How can I figure out if there is labeled traffic in my network?

tcpdump or ethereal.  See my example on http://mpls-linux.sf.net

> - Is there something else which I configured wrong?

Probably not.  It sounds like you are on the right track.

Yes. :-)
