The routing table can be found in the ELSA LANconfig in the 'TCP/IP' configuration
section on the 'Router' tab, or in the
/Setup/IP Router/IP Routing
menu.
This, then, is how an IP routing table might look:
What do the various entries on the list mean?
K
IP addresses and IP network masks
This is the address of the destination network to which data packets may be sent
and its associated network mask. The router uses the network mask and the
destination IP address of the incoming data packets to check whether the packet
belongs to the destination network in question.
The route with the IP address '255.255.255.255' with a network mask of '0.0.0.0' is
the default route. Any data packets which cannot be routed by other routing entries
are transmitted via this route.
K
Router name
The router name indicates what should happen with the data packets that match the
IP address and network mask.
Routes with the router name '0.0.0.0' identify exclusion routes. Data packets for this
“zero route“ are rejected and are not routed any further. This is how routes which
are forbidden on the Internet (private address spaces, e.g. 10.0.0.0), for example, are
excluded from transmission.
If an IP address is input as router name, this is a locally available router, which is
responsible for transfer of the relevant data packets.
K
Distance
Number of routers between your own and the destination router.
Examples with explanatory notes:
IP address IP netmask Router name Dist. This is what happens:
192.168.130.0 255.255.255.0 192.168.140.123 0 All data packets with destination
IP addresses 192.168.130.x are
transmitted to the local router with
the IP address 192.168.140.123.
192.168.0.0 255.255.0.0 0.0.0.0 0 Prevents transfer of all data
packets in reserved IP address
ranges.
172.16.0.0 255.255.0.0 0.0.0.0 0
10.0.0.0 255.0.0.0 0.0.0.0 0
224.0.0.0 224.0.0.0 0.0.0.0 0
