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:

18 # bond1 10.3.3.0/24 10.0.0.1
