Summary of RIP Configuration Tasks
Table 3-2 describes the RIP configuration tasks.

Description |
Task |
|---|---|---|
Configuring basic RIP functions |
Basic RIP functions include enabling RIP, specifying the network segment where RIP runs, and specifying the RIP version. The basic RIP functions must be configured before you use the RIP features. |
|
Configuring RIP-2 features |
RIP-2 is a classless routing protocol, and the RIP-2 packets contain subnet masks. Therefore, deploying a RIP-2 network can save IP addresses. Only RIP-2 can be deployed on a network where the IP addresses are discontinuous, and RIP-1 cannot be used. RIP-2 supports authentication for protocol packets and provides multi-authentication modes to enhance security. |

Preventing routing loops |
RIP is a routing protocol based on the distance vector algorithm. RIP devices advertise their local routing tables to neighbors, so routing loops may occur. RIP uses split horizon and poison reverse to prevent routing loops:

|
Controlling RIP routing |
To use RIP more flexibly on the existing network and meet various user requirements, you can configure different parameters to control RIP routing. |
|
Controlling the advertising and receiving of RIP routes |
In practical applications, to meet network requirements, you can configure different parameters to accurately control the advertising and receiving of RIP routes. |
|
Improving RIP network performance |
In practical applications, you can configure special RIP functions to improve RIP network performance.

Configuring BFD for RIP |
In general, RIP maintains neighbor relationships by periodically sending and receiving Update packets. If a device does not receive the Update packet from a neighbor in the aging time, it considers the neighbor Down. The default value of the aging timer is 180 seconds, so RIP can detect a link fault only after the fault lasts for 180 seconds. If high-speed data services are deployed on the network, a large amount of data will be lost during this period. BFD provides the millisecond-level fault detection mechanism. It can detect faults on the protected links or nodes immediately, and report the faults to RIP. BFD improves the RIP process's response to network topology changes, which implements fast convergence of RIP routes. |

Configuring the Network Management Function for RIP |
By binding RIP to the MIB, you can view RIP information and configure RIP through the NMS. |
