A separate route does not need to be defined that includes the gateway IP address.

It does not matter even if there is a separate route which includes the gateway IP address and

that routes traffic to a different interface.

Composite Subnets can be Specified

Another advantage with the NetDefendOS approach to route definition is that it allows the

administrator to specify routes for destinations that are not aligned with traditional subnet

For example, it is perfectly legal to define one route for the destination IP address range

192.168.0.5 to 192.168.0.17 and another route for IP addresses 192.168.0.18 to 192.168.0.254. This

is a feature that makes NetDefendOS highly suitable for routing in highly complex network

Displaying Routing Tables

It is important to note that routing tables that are initially configured by the administrator can

have routes added, deleted and changed automatically during live operation and these changes

will appear when the routing table contents are displayed.

These routing table changes can take place for different reasons. For example, if dynamic routing

with OSPF has been enabled then routing tables will become populated with new routes learned

from communicating with other OSPF routers in an OSPF network. Other events such as route

failover can also cause routing table contents to change over time.

Example 4.1. Displaying the main Routing Table

This example illustrates how to display the contents of the default main routing table.

Command-Line Interface

To see the routing table contents:

gw-world:/> cc RoutingTable main

gw-world:/main> show

To return the default CLI context:

gw-world:/main> cc

To see the active routing table enter:

gw-world:/> routes
