Re: [mpls-linux-devel] LDP Configuation

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

Hi, again:

This is the scenario I use:


      13.0.0.0/24   .1   .1             .2   .1   11.0.0.0/24
               -------PE1-----------------PE2-------
                  eth2   eth1         eth0   eth1
                            10.0.0.0/24  =20

I've compiled the latest quagga-mpls and ldp-portable from your =
repository:
      =20
        [root@l12p07 ~]# rpm -qa | grep quagga
        quagga-contrib-0.99.5-2006120101_mpls_0.1164964523
        quagga-0.99.5-2006120101_mpls_0.1164964523
        quagga-debuginfo-0.99.5-2006120101_mpls_0.1164964523
        quagga-devel-0.99.5-2006120101_mpls_0.1164964523

I tried what you suggested and this is what happens (on PE2), after =
launching zebra, ospfd and ldpd:


        [root@l12p07 Scripts_Ord2]# vtysh

        Hello, this is Quagga (version 0.99.5).

        PE2# con t
        PE2(config)# mpls static 0
        PE2(config-ls)# label-map gen 160 swap gen 170 nexthop eth1 =
10.0.0.1
        Warning: closing connection to zebra because of an I/O error!
        PE2(config-ls)#

This is what dmesg prints at this time:

[root@l12p07 ~]# dmesg | grep mpls
Linux version 2.6.15-1.1831_FC4mpls_1.950 (root@localhost.localdomain) =

MPLS DEBUG net/mpls/mpls_ilm.c:126:mpls_ilm_dst_alloc: enter
MPLS DEBUG net/mpls/mpls_ilm.c:156:mpls_ilm_dst_alloc: exit

Then I tried with another ip address that doesn't belong to the =
scenario:

Hello, this is Quagga (version 0.99.5).

PE2# con t
PE2(config)# mpls static 0

PE2# show mpls forwarding

PE2#

But the output of dmesg is always the same, although MPLS debug is =
running. This lines are the same that appear as I boot the system and =
load mpls4 and mpls modules. Furthermore, at any time NHLFEs and ILMs =
are empty:

[root@l12p07 Scripts_Ord2]# dmesg | grep mpls

MPLS DEBUG net/mpls/mpls_ilm.c:126:mpls_ilm_dst_alloc: enter
MPLS DEBUG net/mpls/mpls_ilm.c:156:mpls_ilm_dst_alloc: exit

I expect your answer.
Thanks in advance,
