The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter describes the Cisco NX-OS Routing Information Protocol (RIP) commands that begin with I.
To enable authentication for the Routing Information Protocol (RIP) Version 2 packets and to specify the set of keys that can be used on an interface, use the ip rip authentication key-chain command. To prevent authentication, use the no form of this command.
ip rip authentication key-chain name-of-chain
no ip rip authentication key-chain [ name-of-chain ]
|
|
---|---|
This command does not require a license.
Note Make sure the LAN Base Services license is installed on the switch to enable Layer 3 interfaces.
This example shows how to configure the interface to accept and send any key that belongs to the key-chain trees:
|
|
Creates a set of keys that can be used by an authentication method. |
|
Displays a summary of RIP information for all RIP instances. |
To specify the type of authentication used in the Routing Information Protocol (RIP) Version 2 packets, use the ip rip authentication mode command. To restore clear text authentication, use the no form of this command.
ip rip authentication mode { text | md5 }
Clear text authentication is provided for RIP packets if you configured a key chain.
|
|
---|---|
This command does not require a license.
Note Make sure the LAN Base Services license is installed on the switch to enable Layer 3 interfaces.
This example shows how to configure the interface to use MD5 authentication:
|
|
Enables authentication for RIP Version 2 packets and specifies the set of keys that can be used on an interface. |
|
Displays a summary of RIP information for all RIP instances. |
To add an additional value to the incoming IP Routing Information Protocol (RIP) route metric for an interface, use the ip rip metric-offset command. To return the metric to its default value, use the no form of this command.
Value to add to the incoming route metric for an interface. The range is from 1 to 15. The default is 1. |
|
|
---|---|
Use the ip route metric-offset command to influence which routes are used by Cisco Nexus 5500. This command allows you to add a fixed offset to the route metric of all incoming routes on an interface. For example, if you set the metric-offset to 5 on an interface and the incoming route metric is 5, then Cisco Nexus 5500 adds the route to the route table with a metric of 10.
This command does not require a license.
Note Make sure the LAN Base Services license is installed on the switch to enable Layer 3 interfaces.
This example shows how to configure a metric offset of 10 for all incoming RIP routes on Ethernet interface 2/1:
|
|
To add an offset to incoming and outgoing metrics to routes learned via Routing Information Protocol (RIP), use the ip rip offset-list command. To remove an offset list, use the no form of this command.
Value to add to the incoming route metric for an interface. The range is from 1 to 15. The default is 1. |
|
|
---|---|
This command does not require a license.
Note Make sure the LAN Base Services license is installed on the switch to enable Layer 3 interfaces.
This example shows how to configure an offset of 10 for all incoming RIP routes on Ethernet interface 2/1:
|
|
To suppress the sending of the Routing Information Protocol (RIP) updates on an interface, use the ip rip passive-interface command. To unsuppress updates, use the no form of this command.
|
|
---|---|
While RIP stops sending routing updates to the multicast (or broadcast) address on a passive interface, RIP continues to receive and process routing updates from its neighbors on that interface.
This command does not require a license.
Note Make sure the LAN Base Services license is installed on the switch to enable Layer 3 interfaces.
This example shows how to configure Ethernet 1/2 as a passive interface:
|
|
Displays a summary of RIP information for all RIP instances. |
To enable poison-reverse processing of the Routing Information Protocol (RIP) router updates, use the ip rip poison-reverse command. To disable poison-reverse processing of RIP updates, use the no form of this command.
Split horizon is always enabled. Poison-reverse processing is disabled.
|
|
---|---|
Use the ip rip poison-reverse command to enable poison-reverse processing of RIP router updates. By default, Cisco Nexus 5500 does not advertise RIP routes out the interface over which they were learned (split horizon). If you configure both poison reverse and split horizon, then Cisco Nexus 5500 advertises the learned routes as unreachable over the interface on which the route was learned.
This command does not require a license.
Note Make sure the LAN Base Services license is installed on the switch to enable Layer 3 interfaces.
This example shows how to enable poison-reverse processing for an interface running RIP:
|
|
Displays a summary of RIP information for all RIP instances. |
To filter the Routing Information Protocol (RIP) routes coming in or out of an interface, use the route-filter command. To remove filtering from an interface, use the no form of this command.
ip rip route filter { prefix-list list-name | route-map map-name } { in | out }
no ip rip route filter { prefix-list list-name | route-map map-name } { in | out }
Associates a route map to set the redistribution policy for RIP. |
|
|
|
---|---|
Use the ip rip route-filter command to filter incoming or outgoing routes on an interface.
This command does not require a license.
Note Make sure the LAN Base Services license is installed on the switch to enable Layer 3 interfaces.
This example shows how to use a route map to filter routes for a RIP interface:
|
|
---|---|
To configure a summary aggregate address under an interface for the Routing Information Protocol (RIP), use the ip rip summary-address command. To disable summarization of the specified address or subnet, use the no form of this command.
ip rip summary-address ip-prefix / mask
no ip rip summary-address ip-prefix / mask
|
|
---|---|
The ip rip summary-address command summarizes an address or subnet under a specific interface.
This command does not require a license.
Note Make sure the LAN Base Services license is installed on the switch to enable Layer 3 interfaces.
This example shows how to configure the summary address 192.0.2.0 that is advertised out Ethernet interface 1/2:
|
|
Displays a summary of RIP information for all RIP instances. |
To specify the Routing Information Protocol (RIP) instance for an interface, use the ip router rip command. To return to the default, use the no form of this command.
Name of the RIP instance. The instance-tag can be any case-sensitive, alphanumeric string up to 20 characters. |
|
|
---|---|
Before you use this command, make sure that you enable RIP on the switch.
This example shows how to set the RIP instance for an interface:
