+#	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
