==Contoh==
  
−
    Configuring the IPv6 prefix to include in router advertisements. Several prefix specific optional parameters and flags may follow:
+
ip -6 addr add 2345::1/64 dev eth0
 +
vtysh
 +
enable
 +
configure terminal
 +
  interface eth1
 +
    no ipv6 nd suppress-ra
 +
    ipv6 nd prefix 2345::/64    # router-address
  
−
        valid-lifetime - the length of time in seconds during what the prefix is valid for the purpose of on-link determination. Value infinite represents infinity (i.e. a value of all one bits (0xffffffff)).

−
    The value to be placed in the Router Lifetime field of router advertisements sent from the interface, in seconds. Indicates the usefulness of the router as a default router on this interface. Setting the value to zero indicates that the router should not be considered a default router on this interface. Must be either zero or between value specified with ipv6 nd ra-interval (or default) and 9000 seconds.

−
    The value to be placed in the Reachable Time field in the Router Advertisement messages sent by the router, in milliseconds. The configured time enables the router to detect unavailable neighbors. The value zero means unspecified (by this router).
