[mpls-linux-general] Problem no labelspace
|
From: Georg K. <gk...@gi...> - 2002-11-08 11:05:32
|
Hi all,
today I tried sending of labeled packets between adjancent nodes. But
I was facing the kernel message:
"mpls_rcv: MPLS unicast packet recv on interface w/o a labelspace"
I checked that the labelspace needs to be enabled by the LDP during the
do_mpls_labelspace() function. But do_mpls_labelspace() only works if the
ifindex is set correctly. Anyway the function do_mpls_labelspace() is onl=
y
called during config file reading, but the interface data is get afterwar=
ds
when reading the zebra data (after the config file read is done compeltel=
y).
What do you think? Probably I am doing something wrong in teh config file=
?
For your reference I am attaching the mplsd.conf file as well as the
gdb session output:
