Configuring RIPng
45
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 routers 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 broadcast 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 flushed from the routing table 20
seconds after the end of the hold-down period.
BigIron RX(config)# ipv6 router rip
BigIron RX(config-ripng-router)# timers 45 135 10 20
Syntax: [no] timers <update-timer> <timeout-timer> <hold-down-timer>
<garbage-collection-timer>
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 seconds
NOTE
You must enter a value for each timer, even if you want to retain the current setting of a particular
timer.
To return to the default values of the RIPng timers, use the no form of this command.
Configuring route learning and advertising parameters
You 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 interface
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.
