After receiving an RA message, ahost can use these parameters to perform corresponding operations. Table 1-4 lists theconfigurable parameters in an RA message and their descriptions.Table 1-4 Parameters in an RA message and their descriptionsParameters DescriptionCur hop limitWhen sending an IPv6 packet, a host uses the value of thisparameter to fill the Cur Hop Limit field in IPv6 headers.Meanwhile, the value of this parameter is equal to the valueof the Cur Hop Limit field in response messages of thedevice.Prefix informationoptionsAfter receiving the prefix information advertised by thedevice, the hosts on the same link can perform statelessautoconfiguration operations.M flagThis field determines whether hosts use the statefulautoconfiguration to acquire IPv6 addresses.If the M flag is set to 1, hosts use the statefulautoconfiguration to acquire IPv6 addresses. Otherwise,hosts use the stateless autoconfiguration to acquire IPv6addresses, that is, hosts configure IPv6 addressesaccording to their own link-layer addresses and the prefixinformation issued by the router.O flagThis field determines whether hosts use the statefulautoconfiguration to acquire information other than IPv6addresses.If the O flag is set to 1, hosts use the statefulautoconfiguration (for example, DHCP server) to acquireinformation other than IPv6 addresses. Otherwise, hosts usethe stateless autoconfiguration to acquire information otherthan IPv6 addresses.
