User Guidelines
The interval between transmissions should be less than or equal to the IPv6
router advertisement lifetime if you configure the route as a default router by
using this command. To prevent synchronization with other IPv6 nodes, the
actual interval used is randomly selected from a value between the minimum
and maximum values.
The minimum RA interval may never be more than 75% of the maximum RA
interval and never less than 3 seconds.
Example
Example 1. The following example configures an IPv6 router advertisement
interval of 201 seconds for VLAN 1:
console(config)# interface vlan 1
console(config-if)#
ipv6 nd ra interval 201
console(config-if)# exit
Example 2. The following examples shows a maximum RA interval of 200
seconds and a minimum RA interval of 50 seconds:
console(config)# interface vlan 1
console(config-if)#
ipv6 nd ra interval 200 50
console(config-if)# exit
ipv6 nd ra lifetime
Use the ipv6 nd ra lifetime command in Interface Configuration mode to
configure the Router Lifetime value in IPv6 router advertisements on an
interface.
To restore the default lifetime, use the no form of this command.
