TCP/IP Configuration 73
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.
Once you have completed filling in the Network Layer Options
Menu, press ENTER to return to Menu 11. Press ENTER at the
message: ‘Press ENTER to Confirm ...’ to save your selections, or
press ESC at any time to cancel your selections.
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
packets can be forwarded to their destinations. A static route is
