# Virtual IP Address by RIP2 protocol.
# This script manages IP alias in different subnet with quagga/ripd.
# It can add an IP alias, or remove one.
#
# The quagga package should be installed to run this RA
#
# usage: $0 {start|stop|status|monitor|validate-all|meta-data}
#
# The "start" arg adds an IP alias.
# Surprisingly, the "stop" arg removes one. :-)
#
# OCF parameters are as below
# OCF_RESKEY_ip The IP address in different subnet
# OCF_RESKEY_nic The nic for broadcast the route information
