ipv6-address - An IPv6 address including the network prefix and

host address bits.
prefix-length - A decimal value indicating how many contiguous bits

(from the left) of the address comprise the prefix (i.e., the network

portion of the address).
default - Uses default values for remaining parameters.
valid-lifetime - The amount of time that the specified IPv6 prefix is

advertised as being valid. (Range: 0-4294967295 seconds)
preferred-lifetime - The amount of time that the specified IPv6

prefix is advertised as being preferred. The preferred lifetime is

counted down in real time. (Range: 0-4294967295 seconds)
no-autoconfig - Indicates to hosts on the local link that the

specified prefix cannot be used for IPv6 autoconfiguration.
off-link - Indicates that the specified prefix is assigned to the link.

Nodes sending traffic to addresses that contain the prefix consider

the destination to be locally reachable on the link.
