To enable RIPng globally, enter the following command.
device(config-rip-router)#ipv6 router rip
device(config-ripng-router)#
After you enter this command, the device enters the RIPng
conguration level, where you can access several commands that allow you
to congure RIPng.
Syntax: [no] ipv6 router rip
To disable RIPng globally, use the no form of this command.
After enabling RIPng globally, you must enable it on individual Brocade device interfaces. You can enable it on physical as well as virtual
routing interfaces. For example, to enable RIPng on Ethernet interface 1/3/1, enter the following commands.
device(config)# interface ethernet 1/3/1
device(config-if-e100-1/3/1)# ipv6 rip enable
Syntax: [no] ipv6 rip enable
To disable RIPng on an individual device interface, use the no form of this command.
Conguring RIPng timers
TABLE 51 RIPng timers
Timer Description Default
Update Amount of time (in seconds) between RIPng
routing updates.
30 seconds.
Timeout Amount of time (in seconds) after which a route
is considered unreachable.
180 seconds.
Hold-down Amount of time (in seconds) during which
information about other paths is ignored.
180 seconds.
Garbage-collection Amount of time (in seconds) after which a route
is removed from the routing table.
120 seconds.
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 values for all routers and access servers
in the network.
• Setting the update timer to a shorter interval can cause the devices to spend excessive time updating the IPv6 route table.
• Brocade recommends setting the timeout timer value to at least three times the value of the update timer.
• Brocade recommends a shorter hold-down timer interval, because a longer interval can cause delays in RIPng convergence.
The following example sets updates to be advertised every 45 seconds. If a route is not heard from in 135 seconds, the route is declared
unusable. Further information is suppressed for an additional 10 seconds. Assuming no updates, the route is ushed from the routing
table 20 seconds after the end of the hold-down period.
device(config)# ipv6 router rip
device(config-ripng-router)# timers 45 135 10 20
Syntax: [no] timersupdate-timer timeout-timer hold-down-timer garbage-collection-timer
Possible values for the timers are as follows:
• Update timer: 3 through 65535 seconds.
• Timeout timer: 9 through 65535 seconds.
