COMMAND USAGE
◆ The interval between transmissions should be less than or equal to the
IPv6 router advertisement lifetime if you configure a route as a default
router by using the ipv6 nd ra lifetime command.
◆ To prevent synchronization with other IPv6 nodes, the actual interval
used is randomly selected from a value between the minimum value set
by the system (33% of the maximum RA interval) and the maximum
value set by the ipv6 nd ra interval command.
EXAMPLE
The following sets the maximum RA interval to 1800 seconds:
Console(config)#interface vlan 1
Console(config)#ipv6 nd ra interval 1800
Console(config)#
