[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
