 The command 

creates a permanent static route to the network 193.168.10.0 24 via the Serial 1:1 
interface.

Permanent static routes should not be configured over Serial Layer 2 

interfaces that participate in a Primary-Backup pair. For more information on 
Backup interfaces, refer to "Backup Interfaces" on page 44.

Discard Route

Discard Route enables you to prevent forwarding traffic to specific networks. You 
can configure a static route that drops all packets destined to it. This is called a 
discard route, indicated by the “null0” parameter, and is configured using the 

 <network> <mask> null0 

command.

 the command 

 specifies the network 

134.66.0.0 16 as a discard route.

X330WAN enables you to configure the metric to be used in updates that are 
redistributed from one routing protocol to another.
In RIP, the default is 1 and the maximum value is 16. In OSPF, the default is 20.
Set this value before redistribution using the 

 command from 

within the 

 or 

 contexts. This value is used for all types of 

redistributed routes, regardless of which protocol the route was learned from.

An X330WAN OSPF interface can dynamically set a Cost. By default the OSPF 
interface Cost is calculated based on the interface bandwidth, according to the 
formula:

Cost = 100,000/bandwidth (in kbps)

The result is that the higher the bandwidth, the lower the Cost.
To manually configure the Cost of the OSPF interface:
•

Statically configure the Cost using the 

 command from the 

interface context. By using this option, no dynamic bandwidth updates can 
change the Cost. Return to dynamic cost calculation using the 

 

command.

•

Manually set the bandwidth of the interface using the 

 command 

from within the Interface context. In this case, the configured bandwidth and 
not the actual interface bandwidth is taken into account when calculating the 
cost based on the above formula.
