Changing the Multihoming Property to Strict (CLI)
IPMP group will be chosen randomly on a per-connection basis and automatically refreshed if
the chosen IP interface subsequently becomes unusable. Conversely, if a given IP interface is
part of an IPMP group, it cannot be specified in the "interface" field because such a route would
not be highly-available.
Routing entries come from a number of different origins, as identified by the "type" field.
Although the origin of a routing entry has no bearing on how it is used by the system, its origin
does control if and how it can be edited or deleted. The system supports the following types of
routes:

Note that direct routes are configured as network interfaces using either the Configuration >
Network BUI screen or the configuration net interfaces CLI context. Direct routes are not
managed via the Routing BUI screen nor the routing CLI context.

Supported Route Types
Routing Properties
Description
Created and managed by the appliance administrator.
Created automatically by the appliance via the RIP and
RIPng dynamic routing protocols (if enabled).
Created automatically by the appliance part of enabling
an IP interface that is configured to use DHCP. A DHCP
route will be created for each default route provided by
the DHCP server.
Created automatically by the appliance as part of
enabling an IP interface. A system route will be created
for each IP subnet the appliance can directly reach.
Since these routes are directly reachable, the "gateway"
field instead identifies the appliance's IP address on that
subnet.
Created and managed as a network interface property:
Directly Reachable Network(s). Directly reachable
subnet that the local IP address is not a member of,
but to which the datalink of its interface is physically
connected. This improves scalability by conserving IP
addresses, and could ease traffic congestion through core
switches and routers.
Description
Controls the system policy for accepting and
transmitting IP packets when multiple IP interfaces
are simultaneously enabled. Allowed values are
"loose" (default), "adaptive", and "strict". See the
discussion below.
