# PROVIDE: quagga

# KEYWORD: nojail

#
# Add the following line to /etc/rc.conf to enable quagga:
#quagga_enable="YES"
#
# You may also wish to use the following variables to fine-tune startup:
#  quagga_flags="-d"
#  quagga_daemons="zebra ripd ripngd ospfd ospf6d bgpd isisd"
#  quagga_vysh_boot="YES"
# Per daemon tuning may be done with daemon_name_flags
#  zebra_flags="-dP 0"
#  bgpd_flags="-dnrP 0" and so on
# If you want to give the routing deamons a chance to catchup before
# continueing, set quagga_wait_for to a "default" or certain prefix.
#  quagga_wait_for="default"
#
# If the quagga daemons require additional shared libraries to start,
# use the following variable to run ldconfig(8) in advance:
#quagga_extralibs_path="/usr/local/lib ..."
