Re: [mpls-linux-devel] LDP Configuation

Hi!

Thanks for your information.

I have this module loaded into the kernel ever since system boots. I =
decided to make the file "mpls.modules" to have mpls4, mpls and =
mpls_tunnel always loaded to perform LSPs and tunnels experiments.=20

When I type "dmesg" this is the output:

MPLS DEBUG net/mpls/mpls_tunnel.c:279:mpls_tunnel_ioctl: enter
MPLS DEBUG net/mpls/mpls_tunnel.c:298:mpls_tunnel_ioctl: enter

This two lines repeated lots of times, nothing else related to MPLS.
In those mpls_tunnel.c lines there're calls to MPLS_ENTER, that is =
defined in mpls.h as follows: #define MPLS_ENTER MPLS_DEBUG("enter\n"). =
Anyway, I suppose this module (I mean mpls_tunnel) has nothing to do =
with the config I tried for LDPD to open only simple LSPs.

I've tested ILMs and NHLFEs before and after running ZEBRA, OSPFD and =
LDPD and typing the additional commands by vtysh, and they kept empty.

So, do you know where I could look at, any clue...?

Thanks in advance,

Gonzalo.
