This command adds the address 130.10.112.0 with subnet mask 
255.255.255.0 to the routing table. 

If a destination network is reachable with both a static route and a 
learned route, the router uses the static route unless you specify the 
optional Override value in the ADD ROUte command. In that case, if a 
learned route is available to the same network, regardless of metric, it 
overrides the static route. You should specify Override for a path you 
want to use for route redundancy. The Override value is entered at the 
end of the command. 

To add the same static route as described earlier with the Override value 
included, enter: 

OSPF is a dynamic routing protocol that creates routing tables 
automatically. For information about other dynamic routing protocols like 
RIP, see Using Enterprise OS Software. 

Every 30 minutes or every time the router learns a route change for a 
network, it uses multicast packets to report to its neighbors the following 
types of information: 

■

The networks and the directly connected routers 

■

The metric associated with each directly connected router and 
network

In an unchanging topology, OSPF only sends updates every 30 minutes 
while RIP sends updates every 30 seconds. OSPF provides a significant 
savings in network overhead when compared to RIP. 

To enable OSPF on a specified port, use: 

SETDefault !<port> -OSPF CONTrol = Enable 

After OSPF is enabled, the router exchanges routing information with 
other routers using OSPF. 

For more information about fine-tuning your OSPF configuration, see 
Using Enterprise OS Software.
