You can display a switching module’s routing table to determine which routes are configured and whether the routes are operational.

To display the contents of the routing table, enter the following command string from the top level of the Administration Console:

ip route display

The example shows routes for the LANplex 2500 system. The display indicates the configuration of RIP. The default route appears as Default Route.

IP routing is enabled, RIP is active, ICMP router discovery is disabled.

Destination	Subnet mask	Metric	Gateway	Status
158.101.4.0	255.255.255.0	2	158.101.2.8	Static
158.101.3.0	255.255.255.0	2	158.101.1.2	Learned(RIP)
158.101.2.0	255.255.255.	1	--	Direct
158.101.1.0	255.255.255.0	1	--	Direct
Default Route	--	5	158.101.1.2	Learned (RIP)

Defining a Static Before you can define static routes, you must define at least one IP Route interface. Static routes remain in the table until you remove them or the

corresponding interface. Static routes take precedence over dynamically learned routes to the same destination.

Static routes are not included in periodic RIP updates sent by the system.
