Distance
Number of routers between your own and the destination router. This
value is often equated with the cost of the transmission and used to
distinguish between inexpensive and expensive call paths for wide-area
connections. The distance values entered are propagated as follows:
All networks which can be reached while a connection exists to a
destination network are propagated with a distance of 1.
All non-connected networks are propagated with the distance
entered in the routing table (but with a minimum distance of 2) as
long as a free transmitting channel is still available.
The remaining networks are propagated with a distance of 16 (=
unreachable) if there are no longer any channels available.
Remote stations connected using proxy ARP are an exception to this.
These “proxy hosts” are not propagated at all.
Mask.
Use the masquerading option in the routing table to inform the router
which IP addresses to use when transferring the packets.
'Off': No masquerading.
'On': This entry requests a random IP address valid in the Internet
from your provider which is then used for the connection and
masquerading.
'Stat.': Use this entry to request the assignment of a specific IP
address from your provider as entered in the 'TCP/IP' configuration
section on the 'General' tab or in the
/Setup/TCP-IP-module
menu. This address will be used for the connection and
masquerading.
For further information see the 'IP masquerading' section.
Examples with explanatory notes:
IP address Netmask Router Dist. This is what happens:
192.168.1.9 255.255.255.255 FIELD SERVICE 2 The FIELD SERVICE remote station can be rea-
ched at IP address 192.168.1.9.
192.168.120.0 255.255.255.0 ROUTER01 2 All data packets with destination IP addresses
192.168.120.x are transmitted to ROUTER01.
192.168.125.0 255.255.255.0 ROUTER02 3 All data packets with destination IP addresses
192.168.125.x are transmitted to ROUTER02.
