Module Name: src
Committed By: kefren
Date: Thu Dec 30 11:29:22 UTC 2010
Modified Files:
src/usr.sbin/ldpd: Makefile TODO label.c ldp.h ldp_command.c ldp_peer.c
ldpd.8 main.c socketops.c
Added Files:
src/usr.sbin/ldpd: conffile.c conffile.h
Log Message:
* add config file so one can control id, timers and label assignment and
use neighbour specific options - XXX: needs documentation
* add peer authentication using TCP_MD5SIG. Interoperability tested with
Cisco IOS
* use SLIST_FOREACH_SAFE when deleting labels instead of re-looping.
