BigIron RX Series Configuration Guide 112353-1002253-01Configuring RIPng 44• Brocade recommends setting the timeout timer value to at least three times the value of theupdate timer.• Brocade recommends a shorter hold-down timer interval, because a longer interval can causedelays in RIPng convergence.The following example sets updates to be broadcast every 45 seconds. If a route is not heard fromin 135 seconds, the route is declared unusable. Further information is suppressed for anadditional 10 seconds. Assuming no updates, the route is flushed from the routing table 20seconds after the end of the hold-down period.BigIron RX(config)# ipv6 router ripBigIron RX(config-ripng-router)# timers 45 135 10 20Syntax: [no] timers Possible values for the timers are as follows:• Update timer: 3 – 65535 seconds• Timeout timer: 9 – 65535 seconds• Hold-down timer: 9 – 65535 seconds• Garbage-collection timer: 9 – 65535 secondsNOTEYou must enter a value for each timer, even if you want to retain the current setting of a particulartimer.To return to the default values of the RIPng timers, use the no form of this command.Configuring route learning and advertising parametersYou can configure the following learning and advertising parameters:• Learning and advertising of RIPng default routes• Advertising of IPv6 address summaries• Metric of routes learned and advertised on a router interfaceConfiguring default route learning and advertisingBy default, the Brocade device does not learn IPv6 default routes (::/0). You can originate defaultroutes into RIPng, which causes individual router interfaces to include the default routes in theirupdates. When configuring the origination of the default routes, you can also do the following:• Suppress all other routes from the updates• Include all other routes in the updatesFor example, to originate default routes in RIPng and suppress all other routes in updates sent fromEthernet interface 3/1, enter the following commands:BigIron RX(config)# interface ethernet 3/1BigIron RX(config-if-e100-3/1)# ipv6 rip default-information onlyTo originate IPv6 default routes and include all other routes in updates sent from Ethernet interface3/1, enter the following commands.
