Default Route n parameters
The following web pages and associated command line commands are used to set up default IP
routes that route non-local IP addresses not specified in a static route. The parameters are
identical to those on the static route pages with the exception that there are no IP address or
Mask parameters.
Description
Assigns a convenient and memorable description for the route.
Default route via:
Gateway a.b.c.d
Used to override the default gateway IP address configured for the
Ethernet interfaces. Packets matching the route will use the gateway address specified in the
route rather than the address specified on the Ethernet interface configuration page. This
parameter does NOT apply to routes using PPP interfaces.
Interface x,y
The interface used to route the packets is selected from the drop-down list and the interface
instance number is entered into the adjacent text box. The available options are:
• None
• PPP
• Ethernet
•
Tunnel
Metric n
The routing metric to use when the interface is connected. This should have a value between
1
and
16
and is used to select which route should be used when the subnet for a packet
matches more than one of the IP route entries.
Each route may be assigned a
connected metric
and a
disconnected metric
. The connected
metric parameter is used to specify the metric for a route whose interface is active. The
disconnected metric is used to specify the metric for a route whose interface is inactive.
Normally both values should be the same but in some advanced routing scenarios necessary
to use different values.
If a particular route fails, it will automatically have its metric set to
16
which means that it is
temporarily deemed as being out of service. The default out of service period is set by the IP
route out of service parameter. Note that this default period may be overwritten in certain
situations such as when a firewall stateful inspection rule specifies a different period. When a
route is out of service, any alternative routes (with matching subnets) will be used first.
