   3 # Attempt to add a set of static routes.
   4 #
   5 # Do this in "ipreallocated" rather than just "startup" because some
   6 # of the routes might be missing because the corresponding interface
   7 # has not previously had any IPs assigned or IPs were previously
   8 # released and corresponding routes were dropped.
   9 #
  10 # Addition of some routes might fail, errors go to /dev/null.
  11 #
  12 # Routes to add are defined in $CTDB_BASE/static-routes. Syntax is:
  13 #
  14 # IFACE NET/MASK GATEWAY
  15 #
  16 # Example:
  17 #
  18 # bond1 10.3.3.0/24 10.0.0.1
