# OCF Resource Agent compliant IPaddr2 script.

# TODO:
# - Fix up Cluster IP functionality
# - There ought to be an ocf_run_cmd function which does all logging,

# - Make this the standard IP address agent on Linux; the other
# platforms simply should ignore the additional parameters OR can use
# the legacy heartbeat resource script...
#
# OCF parameters are as below

# OCF_RESKEY_broadcast
# OCF_RESKEY_nic
# OCF_RESKEY_cidr_netmask

This Linux-specific resource manages IP alias IP addresses.
It can add an IP alias, or remove one.

<longdesc lang="en">
The base network interface on which the IP address will be brought
online.
