1102 BigIron RX Series Configuration Guide53-1001986-01Configuring RIPng44For more information about performing these configuration tasks, refer to Chapter 43, “ConfiguringBasic IPv6 Connectivity”.By default, RIPng is disabled. To enable RIPng, you must enable it globally on the Brocade deviceand also on individual router interfaces.NOTEYou are required to configure a router ID when running only IPv6 routing protocols.NOTEEnabling RIPng globally on the Brocade device does not enable it on individual router interfaces.To enable RIPng globally, enter the following command.BigIron RX(config-rip-router)#ipv6 router ripBigIron RX(config-ripng-router)#After you enter this command, the Brocade device enters the RIPng configuration level, where youcan access several commands that allow you to configure RIPng.Syntax: [no] ipv6 router ripTo disable RIPng globally, use the no form of this command.After enabling RIPng globally, you must enable it on individual router interfaces. You can enable iton physical as well as virtual routing interfaces. For example, to enable RIPng on Ethernet interface3/1, enter the following commands.BigIron RX(config)# interface ethernet 3/1BigIron RX(config-if-e100-3/1)# ipv6 rip enableSyntax: [no] ipv6 rip enableTo disable RIPng on an individual router interface, use the no form of this command.Configuring RIPng timersTable 180 describes the RIPng timers and provides their defaults.You can adjust these timers for RIPng. Before doing so, keep the following caveats in mind:• If you adjust these RIPng timers, Brocade strongly recommends setting the same timer valuesfor all routers and access servers in the network.• Setting the update timer to a shorter interval can cause the routers to spend excessive timeupdating the IPv6 route table.TABLE 180 RIPng timersTimer Description DefaultUpdate Amount of time (in seconds) between RIPng routing updates. 30 seconds.Timeout Amount of time (in seconds) after which a route is consideredunreachable.180 seconds.Hold-down Amount of time (in seconds) during which information about otherpaths is ignored.180 seconds.Garbage-collection Amount of time (in seconds) after which a route is removed from therouting table.120 seconds.
