RIP Isn't Exactly The Most Complex Routing Protocol On The CCNA Exam, But That Makes It Easy To Overlook Some Of The Important Details You Must Keep In Mind In Order To Pass The Exam! To Help You Review For The Exam, Here Are Just A Few Of Those Details!RIPs Default Behavior Is To Send Version 1 Updates, But To Accept Both Version 1 And 2 Routing Updates.R2(config)router RipR2(config-router)net 172.16.0.0R2(config-router)ZR2show Ip ProtocolsRouting Protocol Is "rip" Sending Updates Every 30 Seconds, Next Due In 6 Seconds Invalid After 180 Seconds, Hold Down 180, Flushed After 240 Outgoing Update Filter List For All Interfaces Is Incoming Update Filter List For All Interfaces Is Redistributing: Rip Default Version Control: Send Version 1, Receive Any Version Interface Send Recv Key-chain Serial0 1 1 2By Default, RIP V2 Autosummarizes Routing Updates Sent Across Classful Network Boundaries.
