i am pretty serious about getting involved;
i have managed to access your repository, compiled quagga-mpls but it
did'n work (as a matter of fact ospfd didn't work); i patched a fresh
quagga-0.98.0 with the quagga patch from the mpls-linux-1.946a package
and got much better results;
however, when configuring quagga-mpls, my patched version and EVEN the
original quagga-0.98.0 version some configuration error messages
showed up (when running autoreconf or ./update-autotools):

root@MPLS4:/usr/src/quagga-test/test/quagga-0.98.0# autoreconf

autoreconf: automake failed with exit status: 1

i have sent a message to the quagga-users list;
is this normal? (does it happen to you - or am i missing some tool)

nevertheless, i compiled it and launched all the necessary daemons
(zebra, ospfd, ldpd)

this is the network topology i used; the link below contains various
show commands for the ldpd daemon

E0, E1, E2 - stands for eth0, eth1, eth2

i used the switch for Internet access and for easy ssh access from one
machine to the other (i only have one monitor)

only the mpls1-E1, mpls-E1, mpls2-E2, mpls3-E2 are running ldpd
mpls3-E1 is also running ospfd (there's another router with the
11.0.1.1 address - but i was afraid to run ldpd on it because of a
crash :D )

this is the link with the output of the show commands for the ldpd
daemon (they use a bit of space and i didn't want to overfill this
message - it's pretty verbose the way it is)

http://atlantis.cs.pub.ro/~razvand/ldpd-output.txt

as you can see the problem is similar to that presented in the link
from the previous mail; there are NO OUTGOING LABELS

i am looking forward for comments and suggestions where to start
"digging" for bugs
