ctdb/config/events.d/11.routing

   1 #!/bin/sh
   2 # script to add entries to the routing table after we have performed a
   3 # take ip event
   4 # (when we do a "releaseip" event and remove an ip address from an interface
   5 #  the kernel might automatically remove associated entries from
   6 #  the routing table. This is where we add them back)
   7 #
   8 # Routes to add are defined in /etc/ctdb/static-routes.
   9 # Syntax is :
  10 # IFACE NET/MASK GATEWAY
  11 #
  12 # Example
  13 # bond1 10.3.3.0/24 10.0.0.1
