lifetime Enter the lifetime in seconds. The amount of time the IPv6 host can use the IPv6
RDNSS address for name resolution. The range is 0 to 4294967295 seconds.
When you specify the maximum lifetime value of 4294967295 or infinite, the
lifetime does not expire. A value of
0 indicates to the host that the RDNSS address
should not be used. You must specify a lifetime using the lifetime or
infinite parameter.
innite Enter the keyword infinite to specify that the RDNSS lifetime does not expire.
