8-8 CHAPTER 8: IP UNICAST ROUTINGenable rip splithorizon Enables the split horizon algorithm for RIP. Default setting isenabled.enable rip triggerupdate Enables triggered updates. Triggered updates are amechanism for immediately notifying a router’s neighborswhen the router adds or deletes routes, or changes themetric of a route. The default setting is enabled.config rip add {vlan | all} Configures RIP on an IP interface. If no VLAN is specified,then all is assumed. When an IP interface is created, perinterface RIP configuration is enabled by default.config rip delete {vlan | all} Disables RIP on an IP interface. When RIP is disabled on theinterface, the parameters are not reset to their defaults.config rip garbagetime {} Configures the RIP garbage time. The default setting is 120seconds.config rip routetimeout {} Configures the route timeout. The default setting is 180seconds.config rip rxmode [none | v1only |v2only | any] {vlan | all}Changes the RIP receive mode for one or more VLANs.Specify:n none — Drop all received RIP packets.n v1only — Accept only RIP version 1 format packets.n v2only — Accept only RIP version 2 format packets.n any — Accept both version 1 and version 2 packets.If no VLAN is specified, the setting is applied to all VLANs.The default setting is “any”.config rip txmode [none | v1only |v1comp | v2only] {vlan | all}Changes the RIP transmission mode for one or more VLANs.Specify:n none — Do not transmit any packets on this interface.n v1only — Transmit RIP version 1 format packets to thebroadcast address.n v1comp — Transmit version 2 format packets to thebroadcast address.n v2only — Transmit version 2 format packets to the RIPmulticast addressIf no VLAN is specified, the setting is applied to all VLANs.The default setting is “v2only”.config rip updatetime {} Changes the periodic RIP update timer. The default settingis 30 seconds.disable rip Disables RIP.disable rip aggregation Disables the RIP aggregation of subnet information on aRIP version 2 interface.(continued)Table 8-3 RIP Configuration Commands (continued)Command Description
