By default, the garbage-collect timer is 120 seconds, the suppress timer is 120 seconds, the timeout timer is 180 seconds, and the update timer is 30 seconds. RIP is controlled by the following timers: • Update timer-Defines the interval between routing updates. • Timeout timer-Defines the route aging time. If no routing update related to a route is received after the aging time, the metric of the route is set to 16 in the routing table. • Suppress timer-Defines how long a RIP route stays in suppressed state. When the metric of a route is 16, the route enters the suppressed state. In suppressed state, only routes which come from the same neighbor and whose metric is less than 16 will be received by the router to replace unreachable routes. • Garbage-collect timer-Defines the interval from when the metric of a route becomes 16 to when it is deleted from the routing table. During the Garbage-Collect timer length, RIP advertises the route with the routing metric set to 16. If no routing update is announced for that route after the Garbage-Collect timer expires, the route will be deleted from the routing table. IMPORTANT: • HP does not recommend changing 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. system-view [Sysname] rip 100 [Sysname-rip-100] timers update 5 timeout 15 suppress 15 garbage-collect 30 validate-source-address Syntax validate-source-address View undo validate-source-address RIP view Default level 2: System level Parameters None Description Use validate-source-address to enable the source IP address validation on incoming RIP routing updates. Use undo validate-source-address to disable the source IP address validation. The source IP address validation is enabled by default. Typically HP does not recommend disabling the validation. 56
