Parameters
•
ipv6-prefix
—IPv6 network number to include in router advertisements. This
argument must be in the form documented in RFC4293, where the address
is specified in hexadecimal using 16-bit values between colons.
•
/
prefix-length
—Length of the IPv6 prefix. A decimal value that indicates
how many of the high-order contiguous bits of the address comprise the
prefix (the network portion of the address). A slash mark must precede the
decimal value.
•
default—Default values used for automatic advertised prefixes configured
as addresses on the interface using the ipv6 address command.
•
no-advertise—Prefix is not advertised.
•
valid-lifetime
—Remaining length of time, in seconds, that this prefix will
continue to be valid, i.e., time until invalidation. A value of 4,294,967,295
represents infinity. The address generated from an invalidated prefix should
not appear as the destination or source address of a packet.
•
preferred-lifetime
continue to be preferred, i.e., time until deprecation. A value of
4,294,967,295 represents infinity. The address generated from a
deprecated prefix should no longer be used as a source address in new
communications, but packets received on such an interface are processed
as expected. The

.
•
no-autoconfig—Indicates to hosts on the local link that the specified prefix
cannot be used for IPv6 autoconfiguration.The prefix will be advertised with
the A-bit clear.
•
off-link—Configures the specified prefix as off-link. The prefix will be
advertised with the L-bit clear. The prefix will not be inserted into the routing
table as a connected prefix. If the prefix is already present in the routing
table as a connected prefix (for example, because the prefix was also
configured using the ipv6 address command), then it will be removed.
•
no-onlink—Configures the specified prefix as not on-link. The prefix will be
advertised with the L-bit clear.
