+#!/bin/sh
+# script to add entries to the routing table after we have performed a
+# take ip event
+# (when we do a "releaseip" event and remove an ip address from an interface
+#  the kernel might automatically remove associated entries from
+#  the routing table. This is where we add them back)
+#
+# Routes to add are defined in /etc/ctdb/static-routes.
+# Syntax is :
+# IFACE NET/MASK GATEWAY
+#
+# Example
+# bond1 10.3.3.0/24 10.0.0.1
