Configuring the IPv6 prefix to include in router advertisements. Several prefix specific optional parameters and flags may follow:
- valid-lifetime - the length of time in seconds during what the prefix is valid for the purpose of on-link determination. Value infinite represents infinity (i.e. a value of all one bits (
- preferred-lifetime - the length of time in seconds during what addresses generated from the prefix remain preferred. Value infinite represents infinity.
- off-link - indicates that advertisement makes no statement about on-link or off-link properties of the prefix.
Default: not set, i.e. this prefix can be used for on-link determination.
- no-autoconfig - indicates to hosts on the local link that the specified prefix cannot be used for IPv6 autoconfiguration.
Default: not set, i.e. prefix can be used for autoconfiguration.
The maximum time allowed between sending unsolicited multicast router advertisements from the interface, in seconds. Must be no less than 3 seconds.
The value to be placed in the Router Lifetime field of router advertisements sent from the interface, in seconds. Indicates the usefulness of the router as a default router on this interface. Setting the value to zero indicates that the router should not be considered a default router on this interface. Must be either zero or between value specified with ipv6 nd ra-interval (or default) and 9000 seconds.
The value to be placed in the Reachable Time field in the Router Advertisement messages sent by the router, in milliseconds. The configured time enables the router to detect unavailable neighbors. The value zero means unspecified (by this router). Must be no greater than
3,600,000milliseconds (1 hour).
Set/unset flag in IPv6 router advertisements which indicates to hosts that they should use managed (stateful) protocol for addresses autoconfiguration in addition to any addresses autoconfigured using stateless address autoconfiguration.
Default: not set
Set/unset flag in IPv6 router advertisements which indicates to hosts that they should use administered (stateful) protocol to obtain autoconfiguration information other than addresses.
Default: not set
