default-information originate
To generate a default route into Routing Information Protocol (RIP), use the default-information originate command in Router Configuration mode. To disable this feature, use the no form of this command.
Syntax
default-information originate no default-information originate
Parameters
N/A
Default Configuration
Default route is not generated by RIP.
Command Mode
Router RIP Configuration mode
User Guidelines
Use the command to enable generation of a default route.
Examples
Example 1 – The following example shows how to originate a default route:
switchxxxxxx(config)# router ripswitchxxxxxx(config-rip)# default-information originateswitchxxxxxx(config-rip)# exit |
default-metric
The default-metric Router RIP configuration mode command sets the default metric value when RIP advertises routes derived by other protocols (for example, by static configuration). The no format of the command sets the default value.
Syntax
default-metric [metric-value] no default-metric
Parameters
- metric-value—Default metric value. Range 1-15.
Default Configuration metric-value—1.
Command Mode
Router RIP Configuration mode
Example
The following example shows how to set the default metric to 2:
switchxxxxxx(config)# router ripswitchxxxxxx(config-rip)# default-metric 2switchxxxxxx(config-rip)# exit |
ip rip authentication key-chain
The ip rip authentication key-chain IP Interface Configuration mode command specifies the set of keys that can be used for and specifies the type of authentication. The no format of the command returns to default.
Syntax
ip rip authentication key-chain name-of-chain no ip rip authentication key-chain
Parameters
- name-of-chain—Specifies the name of key set. The name-change parameter points to list of keys specified by the key chain CLI command.
Default Configuration No defined key chain.
Command Mode
IP Configuration mode
User Guidelines
Use the ip rip authentication key-chain IP Interface Configuration mode command to define a key chain name. Only one key chain may be defined per an IP interface. Each the ip rip authentication key-chain command overrides the previous definition.
In order to have a smooth rollover of keys in a key chain, a key should be configured with a lifetime that starts several minutes before the lifetime of the previous key expires.
Example
The following example shows how to define a chain name:
switchxxxxxx(config)# interface ip 1.1.1.1switchxxxxxx(config-route-map)# ip rip authentication key-chain alphaswitchxxxxxx(config-route-map)# exit |
ip rip authentication mode
The ip rip authentication mode IP Interface Configuration mode command enables authentication. The no format of the command returns to default.
Syntax
ip rip authentication mode {text | md5} no ip rip authentication mode
Parameters
- text—Specifies the clear text authentication.
- md5—Specifies the MD5 authentication.
Default Configuration No authentication.
Command Mode
IP Configuration mode
User Guidelines
If you enable the MD5 authentication, you must configure a key chain name with the ip rip authentication key-chain interface command. If a key chain is not defined for the IP interface or there is not a valid key then RIP packets are not sent on the IP interface and received IP interface packets are dropped.
If you enable the clear text authentication, you must configure a password with the ip rip authentication-key interface command. If a password is not defined for the IP interface then RIP packets are not sent on the IP interface and received IP interface packets are dropped.
Example
The following example shows how to set the md5 mode:
switchxxxxxx(config)# interface ip 1.1.1.1switchxxxxxx(config-route-map)# ip rip authentication mode md5switchxxxxxx(config-route-map)# exit |
ip rip authentication-key
To assign a password to be used by neighboring routers that are using the RIP clear text authentication, use the ip rip authentication-key command in interface configuration mode. To remove the RIP password, use the no form of this command.
Syntax
ip rip authentication-key password no ip rip authentication-key
Parameters
- password—Any continuous string of characters that can be entered from the keyboard up to 16 characters in length.
Default Configuration
No password is specified.
Command Mode
IP Configuration mode
User Guidelines
The password created by this command is used as a “key” that is inserted directly into the RIP header when the switch software originates routing protocol packets.
A separate password can be assigned to each subnetwork. All neighboring routers on the same subnetwork must have the same password to be able to exchange RIP information.
Only one password may be defined per IP interface. Each ip rip authentication-key command overrides the previous definition.
Example
The following example shows how to define a password:
switchxxxxxx(config)# interface ip 1.1.1.1switchxxxxxx(config-route-map)# ip rip authentication mode textswitchxxxxxx(config-route-map)# ip rip authentication-key alph$$12switchxxxxxx(config-route-map)# exit |
ip rip default-information originate
The ip rip default-information originate IP Interface generates a metric for a default route in RIP. The no format of the command disables the feature.

Parameters ranges
- disable—Do not send the default route.
- metric—Default route metric value. Range: 1-15.
Default Configuration
The RIP behavior is specified by the default-information originate command.
Command Mode
IP Configuration mode
Use the command to override the RIP behavior specified by the default-information originate command on a given IP interface.
Example
The following example shows how to enable sending of default route with metric 3:
switchxxxxxx(config)# interface ip 1.1.1.1switchxxxxxx(config-route-map)# ip rip default-information originate 3switchxxxxxx(config-route-map)# exit |
ip rip distribute-list in
The ip rip distribute-list in IP configuration mode command enables filtering of routes in incoming RIP update messages. The no format of the command disables the filtering.
Syntax
ip rip distribute-list access access-list-name in no ip rip distribute-list in

ip rip passive-interface
The ip rip passive-interface IP Interface Configuration mode command disables sending RIP packets on an IP interface. The no format of the command re-enables the sending RIP packets.
Syntax
ip rip passive-interface no ip rip passive-interface
Parameters N/A.
Default Configuration
RIP messages are sent.
Command Mode
IP Configuration mode
User Guidelines
Use the ip rip passive-interface command to stop sending RIP messages on the giving IP interface. To stop RIP messages being sent on all interfaces, use the passive-interface command.
Note. The no ip rip passive-interface command does not override the passive-interface command.
Example
The following example shows how to stop the sending of RIP messages:
switchxxxxxx(config)# interface ip 1.1.1.1switchxxxxxx(config-route-map)# ip rip passive-interfaceswitchxxxxxx(config-route-map)# exit |
ip rip shutdown
The ip rip shutdown IP Interface configuration mode command changes the RIP interface state from enabled to disabled. The no format of the command returns the state to a value of enabled.
Syntax
ip rip shutdown no ip rip shutdown
Parameters
N/A
Default Configuration
Enabled
Command Mode
IP Configuration mode
User Guidelines
Use the ip rip shutdown CLI command to disable RIP on an IP interface without removing its configuration.The ip rip shutdown CLI command may be applied only to RIP interfaces created by the network CLI command. The ip rip shutdown CLI command does not remove the RIP interface configuration.
Example
The following example shows how to disable RIP on the 1.1.1.1 IP interface:
switchxxxxxx(config)# interface ip 1.1.1.1switchxxxxxx(config-route-map)# ip rip shutdownswitchxxxxxx(config-route-map)# exit |
network
The network Router RIP configuration mode command enables RIP on the given IP interfaces. The no format of the command disables RIP on the given IP interfaces and removes its interface configuration.
Syntax
network ip-address [shutdown] no network ip-address
Parameters
- ip-address—An IP address of a switch IP interface.
- shutdown—RIP is enabled on the interface in the shutdown state.
Default Configuration
N/A
Command Mode
Router RIP Configuration mode
User Guidelines
RIP can be defined only on manually-configured IP interfaces, meaning that RIP cannot be defined on an IP address defined by DHCP or on a default IP address.
Use the network CLI command with the shutdown keyword to create RIP on an interface if you are going to change the default values of RIP configuration and the use the no ip rip shutdown CLI command.
Use the no network CLI command to remove RIP on an IP interface and remove its interface configuration.
Examples
Example 1.The following example shows how to enable RIP on IP interface 1.1.1.1 with the default interface configuration:
switchxxxxxx(config)# router ripswitchxxxxxx(config-rip)# network 1.1.1.1switchxxxxxx(config-rip)# exit |
Example 2. The following example enables RIP on 1.1.1.1 in the shutdown state, configures metric and starts RIP:
switchxxxxxx(config)# router ripswitchxxxxxx(config-rip)# network 1.1.1.1 shutdownswitchxxxxxx(config-rip)# exitswitchxxxxxx(config)# interface ip 1.1.1.1switchxxxxxx(config-route-map)# ip rip offset 2switchxxxxxx(config-route-map)# no ip rip shutdownswitchxxxxxx(config-route-map)# exit |
passive-interface (RIP)
To disable sending routing updates on all RIP IP interfaces, use the passive-interface command in Router RIP Configuration mode. To re-enable the sending of RIP routing updates, use the no form of this command.
Syntax
passive-interface no passive-interface
Parameters
N/A
Default Configuration
Routing updates are sent on all IP RIP interfaces.
Command Mode
Router RIP Configuration mode
User Guidelines
After using the passive-interface command, you can then configure individual interfaces where adjacencies are desired using the no ip rip passive-interface command.
Example
The following example sets all IP interfaces as passive and then excludes the IP interface 1.1.1.1:
switchxxxxxx(config)# router ripswitchxxxxxx(config-rip)# passive-interfaceswitchxxxxxx(config-rip)# network 1.1.1.1switchxxxxxx(config-rip)# network 2.2.2.2switchxxxxxx(config-rip)# network 3.3.3.3switchxxxxxx(config-rip)# exitswitchxxxxxx(config)# interface ip 1.1.1.1switchxxxxxx(config-route-map)# no ip rip passive-interfaceswitchxxxxxx(config-route-map)# exit |
redistribute (RIP)
To redistribute routes from one routing domain into a RIP routing domain, use the redistribute command in the Router RIP configuration mode. To disable redistribution, use the no form of this command.
Syntax
redistribute protocol [process-id] [metric {metric-value | transparent}] [match
{internal | external 1 | external 2}] no redistribute protocol [process-id] [match {internal | external 1 | external 2}]
Parameters
- protocol—Source protocol from which routes are being redistributed. It can be one of the following keywords: connected, static, or ospf.
- process-id—The process-id argument is used only together with the ospf keyword and specifies the appropriate OSPF process ID from which routes are to be redistributed. This identifies the routing process. This value takes the form of a nonzero decimal number. If it is omitted then a value of 1 is assumed.
- metric transparent—Causes RIP to use the source protocol metric for redistributed routes as the RIP metric. Only routes with metric less than 16 are redistributed.
- metric metric-value—Specifies the metric assigned to the redistributed routes. The value supersedes the metric value specified using the default-metric command.
- match
{internal | external 1 | external 2}—The match keyword is used only
together with the ospf keyword and specifies the criteria by which OSPF
routes are redistributed into RIP. It can be one of the following:
- internal—Routes that are internal to a specific autonomous system.
- external 1—Routes that are external to the autonomous system, but are imported into OSPF as Type 1 external route.
- external 2—Routes that are external to the autonomous system, but are imported into OSPF as Type 2 external route.
By default the internal and external 1 routes are redistributed.
Note. Multiple redistribute commands with various values of the match keyword may be defined.
Default Configuration
Route redistribution is disabled
Command Mode
Router RIP Configuration mode
User Guidelines
Routes distributed to the source protocol are never redistributed by it
The connected keyword is used to redistribute to RIP routes that correspond to defined IP interfaces on which RIP is not enabled. By default, the RIP Routing Table includes only routes that correspond only to IP interfaces on which it is enabled.
The static keyword is used to redistribute to RIP static routes. By default, static routes are not redistributed to RIP.
If the metric value is set by the route map (by the set metric command) then the value will supersede the metric value specified by the metric-value argument.
If the metric keyword is not defined, then the metric is specified by the default-metric CLI command is assigned to the redistributed routes. If metric value set by the route map is equal or bigger than 16 the route is not redistributed.
Changing or disabling any keyword will not affect the state of other keywords.
Removing options that you have configured for the redistribute command requires careful use of the no form of the redistribute command to ensure that you obtain the result that you are expecting.
Examples
Example 1.The following example enables redistribution of static routes by RIP with transparent metric:
switchxxxxxx(config)# router ripswitchxxxxxx(config-rip)# redistribute static metric transparentswitchxxxxxx(config-rip)# exit |
Example 2. The following example enables redistribution of static routes by RIP with transparent metric and then changes the metric to default:
switchxxxxxx(config)# router ripswitchxxxxxx(config-rip)# redistribute static metric transparentswitchxxxxxx(config-rip)# no redistribute static metric transparentswitchxxxxxx(config-rip)# exit |
Example 3. The following example enables redistribution of static routes by RIP with default metric and then changes the metric to transparent:
switchxxxxxx(config)# router ripswitchxxxxxx(config-rip)# redistribute staticswitchxxxxxx(config-rip)# redistribute static metric transparentswitchxxxxxx(config-rip)# exit |
Example 4. The following example enables redistribution of static routes by RIP with transparent metric. The second redistribute command does not affect:
switchxxxxxx(config)# router ripswitchxxxxxx(config-rip)# redistribute static metric transparentswitchxxxxxx(config-rip)# redistribute staticswitchxxxxxx(config-rip)# exit |
Example 5. The following example disables redistribution of static routes by RIP:
switchxxxxxx(config)# router ripswitchxxxxxx(config-rip)# no redistribute staticswitchxxxxxx(config-rip)# exit |
Example 6. The following example shows how internal and extenal 1 OSPF routes are redistributed into a RIP domain:
switchxxxxxx(config)# router rip switchxxxxxx(config-rip)# redistribute ospf 1switchxxxxxx(config-rip)# exit |
Example 7. The following example shows how internal and external 1 OSPF routes are redistributed into a RIP domain with metric 1 and external 2 OSPF routers with metric 4. The first redistribute command does not include the match keyword because it is a default value:
switchxxxxxx(config)# router ripswitchxxxxxx(config-rip)# redistribute ospf 1 metric 1switchxxxxxx(config-rip)# redistribute ospf 1 match external 2 metric 4switchxxxxxx(config-rip)# exit |
router rip
The router rip Global Configuration mode command specifies the Router RIP mode and enables it if it was disabled. The no format of the command disables RIP globally and removes its configuration.
Syntax
router rip no router rip
Parameters
N/A
Default Configuration
Disabled
Command Mode
Global Configuration mode
User Guidelines
RIP supports the following global states:
- disabled
- enabled
- shutdown
If a value of the RIP global state is disabled (default value), RIP is not operational and cannot be configured. When this state is set, the RIP configuration is removed. The state may be set by the no router rip CLI command from any RIP global state.
If a value of the RIP global state is shutdown, RIP is not operational, but can be configured. When the state is set the RIP configuration is not changed. The state may be set by the shutdown CLI command from the enabled RIP global state.
If the value of the RIP global state is enabled, RIP is operational, and can be configured. The state can be set by the router rip CLI command from the disabled RIP global state and by the no shutdown CLI command from the shutdown RIP global state.
Example
The following example shows how to enable RIP globally:
