A null interface is a virtual interface that discards IP packets and is used to 
prevent routing loops from occurring in the network. 

You do not assign the null interface an IP address. Instead, you create a 
static route for a network and set the next hop to the null interface (null0).

Next-Hop Address

Enter an IP address for the gateway associated with

Cost

Enter the metric between this router and the 
destination. 

Preference

Select a low or high routing preference from the

preference are present, the switch uses the route that 
has the lower cost.
