ipv6 nd ra max-interval


ipv6 nd ra max-interval <TIME>

no ipv6 nd ra max-interval [<TIME>]


Configures the maximum interval between transmissions of IPv6 RAs on the interface. The interval between RA transmissions on an interface is a random value that changes every time an RA is sent. The interval is calculated to be a value between the current max-interval and min-interval settings.

The no form of this command returns the setting to its default, provided the default value is less than the default lifetime value.

  • This value has one setting per interface. The setting does not apply to RAs sent in response to a router solicitation received from another device.

  • Attempting to set max-interval to a value that is not sufficiently larger than the current min-interval also results in an error message.
