[mpls-linux-devel] LDP query

[Neha S. <neh...@gm...>]

Hello,

We have downloaded and installed mpls (1.950) with all other utilities give
in the sourceforge site.

The mpls forwarding engine works fine. we tested the same using "mpls"
command suite provided in iproute2 for mpls 1.950.

Now we are trying to atuomate this using  LDP

When we start ldpd it runs as shown below :-

quagga   11410 11319  0 13:39 pts/1    00:00:00 /usr/sbin/ldpd -f
/etc/quagga/ldpd.conf


when we give the following command:-

VPLS22> en
Password:
VPLS22# con
VPLS22# configure t
VPLS22# configure terminal
VPLS22(config)# mpl
VPLS22(config)# mpls ld
VPLS22(config)# mpls ldp
VPLS22(config-ldp)#


The LDPD daemon/process used to crash abruptly. Upon debugging we found that
"creation of ldp hello socket fails with bind error :  bind failed : :
Permission denied".


As you can see the user id with which the ldpd runs is quagga ...


We had tried the old version of ldp which runs with root as userid . it
starts with no problem and also exchanges the labels. but has problems in
communicating with kernel.

Hence we downloaded the latest LDPD and mpls package (1.950) as given in
sourceforge website.

However when we run the ldpd it fails with the error stated above.

Please suggest us what is to be done to over come this problem. and get ldp
going :-)


Thank you

A quick search of the archives will show that the version of
LDP in the current quagga-mpls release is not designed for users (it
was a development release).

If you are interested in work with LDP and are willing to help
in the debugging process, please download the lastest quagga-mpls from
my development tree (see http://mpls-linux.sf.net for more info)

Make sure to search the archive before posting to the mailing list.

Hello,

Thank you for your response.

I also want to know if the user version of MPLS LDP is available just like
the user version for the MPLS Forwarding Plane. If it is available please
provide me the link for the same.

Regards

Neha Singh.

Re: [mpls-linux-devel] LDP query

[James R. L. <jl...@mi...>]

Hello,

Basically MPLS LDP (quagga-mpls + ldp-portable) is only ready for
people who are willing to help debug.  So far I think there are three
people besides me who have had some level of success using it.  All of them
downloaded the code from my development tree and compiled it themselves.

Until I get more feed back from people about them being able to successfully
use MPLS LDP, I will not release a new version.

I'm on Gentoo with a kernel 2.6.18.2 MPLS (downloaded from the repository)
and GCC 4.1.1 (Gentoo 4.1.1-r1). I would to say that I had to "modify" the
code to compile everything cleanly.

For example, If you have an error like this :
../lib/prefix.h:40: error: expected specifier-qualifier-list before 'u_char=
'
../lib/prefix.h:61: error: expected specifier-qualifier-list before 'u_char=
'
../lib/prefix.h:70: error: expected specifier-qualifier-list before 'u_char=
'
../lib/prefix.h:78: error: expected specifier-qualifier-list before 'u_char=
'
../lib/prefix.h:87: error: expected specifier-qualifier-list before 'u_char=
'
../lib/prefix.h:157: error: expected '=3D', ',', ';', 'asm' or '__attribute=
__'
before 'ip_masklen'

This SHOULD be solve by adding: #include <linux/types.h> but it didn't work
for me (don't know why). So I add them manually (it's ugly, I know)

I created a patch to show you what are my changes :
http://www.info.fundp.ac.be/~jbiscont/file/patch_compile_quagga-mpls.patch<=
http://www.info.fundp.ac.be/%7Ejbiscont/file/patch_compile_quagga-mpls.patc=
h>

This was made according to the latest version of quagga-mpls.

And this is the script to use aclocal, automake, autoconf, blablabla...

I hope it helps and don't forget to create the links for ldp-portable (it's
so obvious that you are able to forget about it ;-) )

Sincerely,
