=================
Configure the VIP
=================
You must select and assign a virtual IP address (VIP)
that can freely float between cluster nodes.
This configuration creates ``vip``,
a virtual IP address for use by the API node (``10.0.0.11``):
For ``crmsh``:
.. code-block:: console
primitive vip ocf:heartbeat:IPaddr2 \
params ip="10.0.0.11" cidr_netmask="24" op monitor interval="30s"
For ``pcs``:
.. code-block:: console
# pcs resource create vip ocf:heartbeat:IPaddr2 \
params ip="10.0.0.11" cidr_netmask="24" op monitor interval="30s"
