DGS-6604 m timers basic timers basic To configure update, timeout, and garbage-collection timers for an IPv6 RIP routing process, use the timers basic command. To return the timers to their default values, use the no form of this command. timers basic update timeout garbage-collection no timers basic Syntax Description update Specifies the interval of time in seconds at which updates are sent. This is the fundamental timing parameter of the RIP IPv6 routing protocol. The value is from 5 to 2147483647. timeout Specifies the interval of time in seconds after which a route is declared invalid. The route becomes invalid when there is an absence of updates that refresh the route. However, the route is still used for forwarding packets.The value is from 5 to 2147483647. garbage-collection Specifies the amount of time in seconds that must pass from when a route becomes invalid until the route is removed from the routing table.The value is from 5 to 2147483647. Default Command Mode Usage Guideline Examples update SECONDS: 30 timeout SECONDS: 180 garbage-collection SECONDS: 120 Router configuration The timers basic command is similar to the command "timers" on page 882. Use the update argument to set the time interval between RIP routing updates. If no route update is received for the time interval specified by the timeout argument, the route is considered unreachable. The use of a timeout interval is not recommended for RIP because it can introduce long delays in convergence. Use the garbage-collection argument to specify the time interval between a route being considered invalid and the route being purged from the routing table. The basic timing parameters for IPv6 RIP are adjustable. IPv6 RIP is executing a distributed, asynchronous routing algorithm, therefore it is important that these timers be the same for all routers and access servers in the network. The following example (on the next page) sets updates every 5 seconds. If a route is not heard from in 15 seconds, the route is declared invalid. Assuming no updates, the route is flushed from the routing table 30 seconds after the end of the hold-down period. CLI Reference Guide 883
