User Guidelines
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.
