60• The timeout timer defines the route aging time. If no routing update related to a route is receivedafter the aging time, the metric of the route is set to 16 in the routing table.• The suppress timer defines how long a RIP route stays in the suppressed state. When the metric ofa route is 16, the route enters the suppressed state. In the suppressed state, only routes which comefrom the same neighbor and whose metric is less than 16 will be received by the router to replaceunreachable routes.• The garbage-collect timer defines the interval from when the metric of a route becomes 16 to whenit is deleted from the routing table. During the Garbage-Collect timer length, RIP advertises the routewith the routing metric set to 16. If no routing update is announced for that route after theGarbage-Collect timer expires, the route will be deleted from the routing table.NOTE:• Do not change the default values of these timers.• The time lengths of these timers must be kept consistent on all routers in the network.Examples# Specifies the update, timeout, suppress, and garbage-collect timers as 5, 15, 15 and 30 respectively. system-view[Sysname] rip 100[Sysname-rip-100] timers update 5 timeout 15 suppress 15 garbage-collect 30validate-source-addressSyntaxvalidate-source-addressundo validate-source-addressViewRIP viewDefault level2: System levelParametersNoneDescriptionUse the validate-source-address command to enable the source IP address validation on incoming RIProuting updates.Use the undo validate-source-address command to disable the source IP address validation.The source IP address validation is enabled by default.Typically H3C does not recommend disabling the validation.Examples# Disable the source IP address validation on incoming RIP routing updates. system-view[Sysname-rip] rip 100[Sysname-rip-100] undo validate-source-address
