[mpls-linux-devel] LDPD configuration

[<gsr...@al...>]

Hi!

After testing static configurations of LSPs and tunnels, now I'm trying =
to
automate the process. I've compiled and succesfully installed =
quagga-mpls
and ldp-portable from your p4 repository including the links created =
with
"create-links" file within the ldpd directory. Now, I'm able to run ospf =
but
I have some problems with ldp.

This is the scenario I use to test it:

13.0.0.0/24   .1   .1          .2   .1          .2   .1   14.0.0.0/24
         -------PE1--------------PE2--------------PE3-------
            eth2   eth0      eth1   eth0      eth1   eth2
                    10.0.0.0/24      11.0.0.0/24

And the .conf files in PE2:

Within "ldpd.conf" I have to comment(!) many lines and execute them via
command line, otherwise the daemon would not start. Also, I did realize =
that
after doing this, they don't appear on the "running config" of ldpd. The
only command that show up is "mpls ldp".

I'd like to configure a LSP from PE1 to PE3, so on PE3 I also put the
command "egress connected".

I capture ldp HELLOs discovering the neighbors and KEEPALIVEs. The HELLO
packets carry the LSR-Id set on the command line but the KEEPALIVEs from =
PE2
to PE1 and PE3, always contained a bad TCP CheckSum. Furthermore I don't =
see
any message regarding sesion activation.

Any information about these problems could be very useful.

Thanks in advance,

regards

Gonzalo.
