Static Networks
Subnet Mask
A subnet mask determines which bits in the IP address are used to identify the network number.
It is also a method of extending the IP Network Address so that a site may use one network
address for several different networks.
Metric
A numeric value indicating the distance from a local network to the destination network.
Originally this measured by the number of gateways between the two networks, the number may
be modified, either higher or lower, to indicate a desired priority. To ensure a route is considered
primary, the value must be less than that of a secondary route. This field is only used on IP
networks. Range 1 to 15. (Please note that a value of 1 usually indicates a direct network.)
Hops
See Metric, above. When defining the number of hops in a given route, remember to increment
the actual number by 1, since your locally attached unit is counted as “1”. This field is only used
on IPX networks. Range 1 to 15.
Ticks
Indicates the distance between two networks as measured in time increments
(1/18th of a second). Only IPX Networks use this information. Like hops, ticks may be used to
designate primary and secondary routes to the same network. Although both the hops and ticks
values are considered when determining routing priority, for Novell networks, the tick value is
considered first. To designate routing priority between two routes, the preferred tick value will
be lower. Range 1 to 15.
Next Gateway
Enter the IP Address of the first gateway (Adit or router) that the data will use to reach the
destination network. Referring back to Example 1, Network B would enter the IP Address of
Router 1, since that is the first gateway on the route to Network C. This field is only used on IP
Networks.
Next IPX Router
Enter the MAC Address of the next gateway (Adit or router) on the route that the data will use
to reach the destination network. Referring back to Example 1, Network B would enter the
MAC Address of Router 1, since that is the next gateway on the route to Network C. This field
is only used on IPX networks.
