Re: [mpls-linux-devel] LDP Configuation

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

Hi, James:

This is what I get with "dmesg" related to mpls as soon as system boots. =
I
have also loaded the "mpls4" module that at the same time loads "mpls"
module:

[root@PE1 ~]# lsmod | grep mpls
mpls4                   6081  0
mpls                   78465  2 mpls4

Linux version 2.6.15-1.1831_FC4mpls_1.950 (jleu@jleu-laptop) (gcc =
version
4.0.2 20051125 (Red Hat 4.0.2-8)) #1 Sun Feb 26 15:00:23 CST 2006

MPLS: version 1.950
MPLS: protocol driver interface - <jl...@mi...>
MPLS DEBUG net/mpls/mpls_sysfs.c:130:mpls_sysfs_init: enter MPLS DEBUG
net/mpls/mpls_sysfs.c:139:mpls_sysfs_init: exit
MPLS: IPv4 over MPLS support
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

These are the new lines output by dmesg when I type:

[root@PE1 ~]# mpls ilm show
[root@PE1 ~]# mpls nhlfe show

MPLS DEBUG net/mpls/mpls_netlink.c:204:genl_mpls_ilm_dump: Enter: entry =

MPLS DEBUG net/mpls/mpls_netlink.c:221:genl_mpls_ilm_dump: Exit: entry 0
MPLS DEBUG net/mpls/mpls_netlink.c:394:genl_mpls_nhlfe_dump: Enter: =
entry 0
MPLS DEBUG net/mpls/mpls_netlink.c:411:genl_mpls_nhlfe_dump: Exit: entry =
0

The next I tried was to create a NHLFE entry and an ILM entry:

[root@PE1 ~]# mpls nhlfe add key 0
NHLFE entry key 0x00000002 mtu 0 propagate_ttl
         (0 bytes, 0 pkts)

[root@PE1 ~]# mpls ilm add label gen 100 labelspace 0

[root@PE1 ~]# mpls nhlfe show
NHLFE entry key 0x00000002 mtu 0 propagate_ttl
         (0 bytes, 0 pkts)

[root@PE1 ~]# mpls ilm show
ILM entry label gen 100 labelspace 0 proto ipv4
        pop peek  (0 bytes, 0 pkts)

...and their respective lines in dmesg output:

I hope you'll have a look at it and you could tell me something about.

If it helps here are the RPMs installed related to MPLS:
