Hi jim n all,

I really need your help , my ldp-portable doesn't work properly and I don't know what is wrong?!
I have redhat 7.2 with kernel 2.4.13 (MPLS patched).I got the latest ldp-portable via CVS ,first, I have a simple question:I compiled ldp-portable in directory ldp-portable by typing "make ldp_linux" and it was compiled successfully,is it compiled with MPLS_LINUX ?How can I make sure?(The first line in the Makefile in directory ldp-portable:CFLAGS = -g -I. -wall -D__LDP_LINUX__ -Werror
#-DMPLS_LINUX).

I have configured 2 machines as follows :

[Kiyoung J. <jj...@ic...>]

I think you should include -DMPLS_LINUX option in CFLAGS to
work with MPLS forwarding engine in Linux kernel.
As you can see, this option is commented out.
This should be :

CFLAGS = -g -I. -wall -D__LDP_LINUX__ -Werror -DMPLS_LINUX

Regards.
