Routing Commands

M4100 Series ProSAFE Managed Switches

Note: If you use the connected keyword for <protocol>, the all option is

not available because there are no best or non-best connected routes.

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:

• Days:Hours:Minutes if days > = 1

• Hours:Minutes:Seconds if days < 1

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. The reject route added in the RTO

is of the type OSPF Inter-Area. Reject routes (routes of REJECT type installed by any

protocol) are not redistributed by OSPF/RIP. Reject routes are supported in both OSPFv2

and OSPFv3.

Format show ip route [{<ip-address> [<protocol>] | {<ip-address> <mask>

[longer-prefixes] [<protocol>] | <protocol>} [all] | all}]

Modes • Privileged EXEC

• User EXEC
