3.1.4 Routing
Static routing is the term used to refer to a manual method that is used to set up routing between networks.
Static routing has the advantage of being predictable and simple to set up.
This section lists the routing table and lets the user add and delete routes.
Parameter Description
Select To enter network route select “Net”.
To enter a route to a host select “Host”.
Destination the destination network or host. You can provide IP addresses in dotted decimal
or host/network names.
Mask The network's IP address together with its address mask defines a range of IP
addresses. For IP subnets, the address mask is referred to as the subnet mask.
For host routes, the mask is "all ones" (in dotted decimal 255.255.255.255).
Gateway Next hop (gateway); the next router which knows how to reach the destination
Interface Identity of network interface through which a packet will be sent to reach the
gateway.
Metric The 'distance' to the target (usually counted in hops). It is not used by recent
kernels, but may be needed by routing daemons.
Persistent Displays whether a particular route is persistent or not.
Active Displays whether a particular route is active or not.
