Configure RIP 419

Configuring RIP RIP is a Distance-Vector algorithm routing protocol. It uses the split-horizon Horizontal algorithm to avoid loop routes. Split-horizon means that routes received at a

Segmentation on the certain interface are not sent to the same interface. If correct transmission of Interface routes is more important than efficiency, then split-horizon should be disabled.

Disabling split-horizon mechanism is not effective on point-to-point connection links.

Perform the following configurations in interface view.

Table 478 Configure RIP Horizontal Segmentation on the Interface

Operation

Command

 

 

 

Configure RIP horizontal segmentation on

rip split-horizon

the interface

 

 

 

 

 

Prohibit the interface from using

undo rip

split-horizon

split-horizon when sending RIP packets.

 

 

 

 

 

By default, the interface use split-horizon when sending RIP packets.

Configuring Route RIP allows importing the routes learned from other protocols.

Import for RIP

Perform the following configurations in RIP view.

Table 479 Configure Route Import for RIP

Operation

Command

 

 

Configure route import for RIP

import-route protocol [ cost cost ] [

 

route-policy policy-name]

 

 

Cancel route distribution for RIP

undo import-route protocol

 

 

By default, RIP does not import routes from other domains into the routing table.

The protocol attribute specifies the source routing domain that can be imported.

At present RIP can import routes domain such as Connected, Static, OSPF,

OSPF-ASE, and BGP.

See“Configure Route Import” in “Configuration of IP Routing Policy” for the details of importing routes.

Specifying Default The import-routecommand is used to import routes of other routing protocols. Route Metric Value for If import-routeis not followed by the value of a routing metric, then the

RIP parameter value of default-medcommand is set as the metric value when distributing other routing protocols.

Perform the following configurations in RIP view.
