Description Lucy Bopf 2017-03-16 03:35:40 UTC 
In RHV 4.1, users can now set the default route of a host.
 
RHV sets the management network as each host's default route. Some customers prefer the management network to be a local non-routed network, and that another network serves as a default route.

1. In the Manager, open a console and add the custom property.
# engine-config -s UserDefinedNetworkCustomProperties='default_route=^(true|false)$'
# servicectl restart ovirt-engine

2. On each host:
   2.1 Set the property to False on the management (ovirtmgmt|rhevm) network
   2.2 Set the property to True on the desired new default route network
   2.3 Set a next-hop IP address (Gateway) in the new default route network

3. Apply configurations

Two important notes that must be added to the docs:
* This configuration is PER HOST, and needs to be done on each host.
* If the gateway for the new default route network is not set, it will be IGNORED. Leaving the gateway blank will NOT set device based route (such as for proxy-arp scenarios).
