Route Codes
The key for the routing protocol codes that might appear in the routing table output.
The show ip route command displays the routing tables in the following format:
Code
IP-Address/Mask [Preference/Metric] via Next-Hop, Route-Timestamp, Interface
The columns for the routing table display the following information:
Term
Definition
Code
The codes for the routing protocols that created the routes.
IP-Address/Mask
The IP-Address and mask of the destination network corresponding to this route.
Preference
The administrative distance associated with this route. Routes with low values are preferred over
routes with higher values.
Metric
The cost associated with this route.
via Next-Hop
The outgoing router IP address to use when forwarding traffic to the next router (if any) in the path
toward the destination.
Route-Timestamp The last updated time for dynamic routes. The format of Route-Timestamp will be
• Days:Hours:Minutes if days > = 1
• Hours:Minutes:Seconds if days < 1
Interface
The outgoing router interface to use when forwarding traffic to the next destination. For reject routes,
the next hop interface would be Null0 interface.
To administratively control the traffic destined to a particular network and prevent it from being forwarded through the router,
you can configure a static reject route on the router. Such traffic would be discarded and the ICMP destination unreachable
message is sent back to the source. This is typically used for preventing routing loops. Reject routes (routes of REJECT type
installed by any protocol) are not redistributed by RIP.
Example: The following shows example CLI display output for the command.
(DWS-4026) #show ip route
