# ip-down.ipv6to4
#
#
# Taken from:
# (P) & (C) 2000-2001 by Peter Bieringer <pb@bieringer.de>
#
# Version 2001-07-15a
#
# Calling parameters:
#  $1: interface name
#
# Called by (mostly) /etc/ppp/ip-down.local
#  like: /etc/ppp/ip-down.ipv6to4 $1 >>/var/log/ppp-ipv6to4.log 2>&1
#
# Uses following information from /etc/sysconfig/network:
#  NETWORKING_IPV6=yes|no: controls IPv6 initialization (global setting)
#
# Uses following information from /etc/sysconfig/network-scripts/ifcfg-$1:
#  IPV6TO4INIT=yes|no: controls configuration
#  IPV6TO4_RELAY=IPv4addr: remote IPv6to4 relay address
#  IPV6TO4_ROUTING="eth0-:f101::0/64 eth1-:f102::0/64": information to setup local subnetting
#  IPV6TO4_CONTROL_RADVD=yes|no: controls radvd triggering
#  IPV6TO4_RADVD_PIDFILE=file: PID file of radvd for sending signals, default is "/var/run/radvd/radvd.pid"
