TCP/IP Configuration 75
9. Metric - The metric represents the “cost” of transmission for
routing purpose. IP routing uses hop count as the measurement of
cost, with a minimum of 1 for directly connected networks. Enter a
number that approximates the cost for this link. The number need
not be precise, but it must be between 1 and 16. In practice, 2 or 3
is usually a good number.
10. Private - This parameter determines if the Prestige will include the
route to this Remote Node in its RIP broadcasts. If set to yes, this
route is kept private and not included in RIP broadcast. If no, the
route to this Remote Node will be propagated to other hosts
through RIP broadcasts.
11. RIP - This parameter determines how the Prestige handles RIP
(Routing Information Protocol), and the default is Both. If set to
Both, the Prestige will broadcast its routing table on the WAN, and
incorporate RIP broadcasts by the other router into its routing table.
If set to In Only, the Prestige will not broadcast its routing table on
the WAN; if set to Out Only, the Prestige will broadcast its routing
table but ignores any RIP broadcast packets that it receives. If set
to None, the Prestige will not participate in any RIP exchange with
other routers. Usually, you should leave this parameter at its default
of Both and let RIP propagate the routing information automatically.

Static Route Setup
On a directly connected internet, RIP usually handles the routing
automatically. However, RIP cannot propagate across isolated
networks, as in the case before a connection is made between the two
subnetworks using one Class C IP address. Without a route, no
