Configuring RIPng
44
•
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
Configuring default route learning and advertising
By default, the Brocade device does not learn IPv6 default routes (::/0). You can originate default
routes into RIPng, which causes individual router interfaces to include the default routes in their
updates. 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 updates
For example, to originate default routes in RIPng and suppress all other routes in updates sent from
Ethernet interface 3/1, enter the following commands:
BigIron RX(config)# interface ethernet 3/1
BigIron RX(config-if-e100-3/1)# ipv6 rip default-information only
To originate IPv6 default routes and include all other routes in updates sent from Ethernet interface
3/1, enter the following commands.
