In addition to the normal routing table, the gateway can also make routing deci-
sions based on an extended routing table. Apart from the source and destina-
tion address, the gateway can also include the protocol, source and destination
port, type of service (TOS) and the status of the gateway interface in the deci-
sion.
Entries in the Extended Routing Table are treated preferentially compared with
entries in the normal routing table.
To create extended IP routing entries, press the
ADDEXT
button to open the rel-
evant menu.
Example
Extended IP Routing (XIPR) is useful, for example, if two networks are connect-
ed via ISDN with a LAN-LAN connection, but certain services (e.g. Telnet)
should be routed over an X.25 link and not over an ISDN switched connection.
By making entries in the Extended Routing Table, you can allow part of the IP
traffic to run over the ISDN switched connection and part of the IP traffic (e.g.
for Telnet) to run over an X.25 link.
Metric
The lower the value, the higher the priority of
the route (possible values
0
...
15
).
The default value is
1
.
