RIP Network Adjustment and Optimization 297Configuration Tasks Configuring RIP timersn When configuring the values of RIP timers, you should take network performanceinto consideration and perform consistent configuration on all routers running RIPto avoid unnecessary network traffic and network route oscillation.Configuring split horizonn Split horizon cannot be disabled on a point-to-point link.Configuring RIP-1 packet zero field checkn Some fields in a RIP-1 packet must be 0, and they are known as zero fields. ForRIP-1, zero field check is performed on incoming packets, those RIP-1 packets withnonzero value in a zero filed will not be processed further. As a RIP-2 packet hasno zero fields, this configuration is invalid for RIP-2.Setting RIP-2 packet authentication modeRIP-2 supports two authentication modes, simple authentication and MD5authentication.Table 224 Configure RIP timersOperation Command DescriptionEnter system view system-view -Enter RIP view rip -Set the values of RIP timers timers { update update-timer |timeout timeout-timer } *OptionalBy default, Update timervalue is 30 seconds andTimeout timer value is 180seconds.Table 225 Configure split horizonOperation Command DescriptionEnter system view system-view -Enter interface view interface interface-typeinterface-number-Enable split horizon rip split-horizon OptionalBy default, an interface usessplit horizon to send RIPpackets.Table 226 Configure RIP-1 packet zero field checkOperation Command DescriptionEnter system view system-view -Enter RIP view rip -Enable zero field check of RIP-1packetscheckzero OptionalBy default, zero field checkis performed on RIP-1packets.
