The routing table can be found in the ELSA LANconfig in the 'IP-router' on the
'Routing' tab, or in the
/Setup/IP-router-module/IP-routing-
table
menu. This, then, is how an IP routing table might look:
What do the various entries on the list mean?
IP addresses and netmasks
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 network mask
“0.0.0.0” is the default route. All data packets that cannot be routed by
other routing entries are sent over this route.
Router
The router transmits the appropriate data packets to the IP address and
network mask to this remote station. A name is entered at this point if the
remote station is a router in another network or an individual workstation
computer. This is where the IP address of another router which knows the
path to the destination network is entered if the router on the network
cannot address the remote station itself.
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.
