Route metrics can be altered automatically according to various circumstances. This is in
order to provide automatic backup connection paths.
Routes and interfaces can be put out of service.
Whenever an interface is out of service (oos) any route pointing at the interface will also be
out of service.
Whenever a route is out of service, the metric value will be set to 16 in TransPort routing
mode and 17 in CIDR mode.

Enable CIDR routing
When this checkbox is checked, the following six text boxes are revealed:
Connected Interfaces
The value in this text box specifies the CIDR metric that the router should apply to
connected interfaces.
Static Routes
The value in this text box is the CIDR metric that the router should use for static routes.
(Default 1)
eBGP Routes
The value in this text box is the CIDR metric that the router should use for eBGP routes.
(Default 20).
OSPF Routes
The value in this text box is the CIDR metric that the router should use for OSPF routes.
(Default 110)
RIP Routes
The value in this text box is the CIDR metric that the router should use for RIP routing.
(Default 120).
iBGP Routes
The value in this text box is the CIDR metric that thae router should use for iBGP routes.
(Default 200).
Maximum static route metric
The value in this text box defines the maximum value for the routing metric. The default
value is 16.
Route directed IP broadcasts
When checked, this checkbox causes the router to route directed broadcasts. The default
state for this parameter is “Off”. A directed broadcast is an IP packet with a destination
address that is a valid broadcast address for a subnet but does not originate from that
subnet. Directed IP broadcasts are used to send a broadcast from one interface to the
subnet of another.
Wait s seconds before using an alternative route
The value in this text box specifies the latency to apply before passing traffic on an
alternative route in the current route becomes unavailable.
If an interface is configured for “dial on demand” and fails to connect,
Mark a static route as “Out Of Service” for s seconds
The value in this text box specifies the default time that a route should be marked as out of
service if the interface it uses fails to establish a connection.
