+# Version 2005-09-22
+#
+# Note: if called as (like normally) by /etc/sysconfig/network-scripts/ifdown
+# exit codes aren't handled by "ifdown"
+#
+# Uses following information from /etc/sysconfig/network-scripts/ifcfg-$1:
+# DEVICE=<device>
+# IPV6INIT=yes|no: controls IPv6 configuration for this interface
+#
+# Optional for 6to4 tunneling:
+# IPV6TO4_RELAY=<IPv4 address>: IPv4 address of the remote 6to4 relay [default: 192.88.99.1]
+# IPV6TO4_ROUTING="<device>-<suffix>/<prefix length> ...": information to setup internal interfaces
+#
+# Optional for 6to4 tunneling links to trigger radvd:
+# IPV6_CONTROL_RADVD=yes|no: controls radvd triggering [optional]
+# IPV6_RADVD_PIDFILE=<file>: PID file of radvd for sending signals, default is "/run/radvd/radvd.pid" [optional]
+# IPV6_RADVD_TRIGGER_ACTION=startstop|reload|restart|SIGHUP: how to trigger radvd [optional, default is SIGHUP]
+#
+# Required version of radvd to use 6to4 prefix recalculation
+# 0.6.2p3 or newer supporting option "Base6to4Interface"
+# Required version of radvd to use dynamic ppp links
+# 0.7.0 + fixes or newer
