Setting the lifetime of advertised IP addresses

About the lifetime of advertised IP addresses

An RA contains a lifetime field that specifies the lifetime of advertised IP addresses. If the host does not receive a new RA for an IP address within the address lifetime, the host removes the route entry.

All the IP addresses advertised by an interface, including proxy-advertised IP addresses and the interface IP address, have the same lifetime.

    The default lifetime is 1800 seconds.
