The following table describes the nonconfigurable information displayed on the screen.
Specify Route Preferences
You can configure the default preference for each protocol, for example, 60 for static routes, 
120 for RIP. These values are arbitrary values in the range of 1 to 255 and are independent of 
route metrics. Most routing protocols use a route metric to determine the shortest path known 
to the protocol, independent of any other protocol.
The best route to a destination is chosen by selecting the route with the lowest preference 
value. When there are multiple routes to a destination, the preference values are used to 
determine the preferred route. If there is still a tie, the route with the best route metric is 
chosen. To avoid problems with mismatched metrics (such as RIP and Open Shortest Path 
First [OSPF] metrics, which are not directly comparable) you must configure different 
preference values for each of the protocols. 
Table 122.  Route Configuration - Learned Routes 
 
Field
Description
Network Address
The IP route prefix for the destination.
Subnet Mask
Also referred to as the subnet/network mask, this indicates the portion 
of the IP interface address that identifies the attached network.
Protocol
This field tells which protocol created the specified route. The 
possibilities are one of the following:
• 
Local
• 
Static
Route Type
This field can be either default or static. 
Next Hop Interface
The outgoing router interface to use when forwarding traffic to the 
destination.
Next Hop IP Address
The outgoing router IP address to use when forwarding traffic to the 
next router (if any) in the path toward the destination. The next router is 
always one of the adjacent neighbors or the IP address of the local 
interface for a directly attached network.
Preference
The preference is an integer value from 0 to 255. The user can specify 
the preference value (sometimes called administrative distance) of an 
individual static route. Among routes to the same destination, the route 
with the lowest preference value is the route entered into the forwarding 
database. By specifying the preference of a static route, the user 
controls whether a static route is more or less preferred than routes 
from dynamic routing protocols. The preference also controls whether a 
static route is more or less preferred than other static routes to the 
same destination.
Metric
Administrative cost of the path to the destination. If no value is entered, 
default is 1. The range is 0–255.
