8.3.2.19. ipv6 nd prefix
This command is used to configure parameters associated with prefixes the router advertises in its router
advertisements. The first optional parameter is the valid lifetime of the router, in seconds. You can specify a
value or indicate that the lifetime value is infinite. The second optional parameter is the preferred lifetime of the
router.
The router advertises its global IPv6 prefixes in its router advertisements (RAs). An RA only includes the prefixes
of the IPv6 addresses configured on the interface where the RA is transmitted. Addresses are configured using
the ipv6 address interface configuration command. Each prefix advertisement includes information about the
prefix, such as its lifetime values and whether hosts should use the prefix for on-link determination or address
auto-configuration. Use the ipv6 nd prefix command to configure these values.
The ipv6 nd prefix command allows you to preconfigure RA prefix values before you configure the associated
interface address. In order for the prefix to be included in RAs, you must configure an address that matches the
prefix using the ipv6 address command. Prefixes specified using ipv6 nd prefix without associated interface
address will not be included in RAs and will not be committed to the device configuration.
To set prefix configuration to default values, use the no form of this command.
