[mpls-linux-general] problem in ldp_linux

[Venisa C. <vca...@ho...>]

Hi all,

I have installed succesfully both Sourceforge's mpls and ldp-portable (CVS 
version) in my linux-based computers. I am using linux kernel 2.4.3 and 
following the basic configuration in file README.Ingress.
I am also using zebra so that I do not need to explicitly add the routes in 
my mpls configuration scripts in each mpls-enable computers. So far, if I 
use the mplsadm tool (that is, to setup LSP manually) the mpls encapsulation 
works very well, I can see the labels in every packets traversing my mpls 
network. Many thanks to James R. Leu :-))

My problem arises when I start using ldp_linux (that is, trying to setup LSP 
dynamically). I have compiled succesfully ldp_linux with the -DMPLS_LINUX 
flag. I have followed the configuration in file README.sample and I also use 
zebra for establishing the routes. I have changed the address of lo 
interfaces and I let zebra to create the routes for these interfaces and it 
works ! I can see the routes for these interfaces in the FIBs and I can ping 
these interfaces from the other computers. I can see the LDP messages 
(Hello, Initialization, KeepAlive, Address, Label Mapping, ...) when I use 
ldp_linux. I can see also that ldp_linux updates the mpls proc filesystem 
"mpls_in", but unfortunately only "mpls_in". I can see nothing in the other 
proc filesystems (mpls_out and mpls_fec) that are important for creating the 
LSPs. That is why I cannot see anymore the mpls encapsulation in my mpls 
network ... :'-(

I know that someone has experienced this kind of problem, would he please 
share his experiences with me or could someone please tell me if I might 
have misconfigured or forgotten something that is important ? James ?

Or should I use the ldp_zebra instead ? But I cannot quite understand the 
functionality of ldp_zebra because even with ldp_linux I can use zebra to 
establish the routes ...

Any help will be greatly appreciated ...
