10.3.2.18 ipv6 nd prefix
This command sets the IPv6 prefixes to include in the router advertisement. 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.
Syntax
ipv6 nd prefix <prefix/prefix_length> [{<0-4294967295> | infinite}
{<0-4294967295> | infinite}] [no-autoconfig off-link]
no ipv6 nd prefix
no – This command sets prefix configuration to default values.
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.
