Wherein, the confirmation message carries interface IP address and whether interface IP address effectively identifies.
Further, one or more interface IP addresses that second network equipment may be carried in the first RA message, when first
When RA message carries one or more interface IP addresses of second network equipment, does not receive and be used to indicate interface IP address and effectively confirm
Message includes following situations:
Situation one: when the first RA message carry second network equipment one or more interface IP address whole DOWN or
Failure, second network equipment can not receive the first RA message, then first network equipment will not receive in predetermined period
Confirmation message, then it is assumed that one or more interface IP addresses of second network equipment carried in the first RA message are all invalid.
Two: the second network equipment of situation receives the first RA message, judges the one or more carried in the first RA message
Whether interface IP address is effective, then to first network device replied confirmation message, carries the one or more in the confirmation message
In interface IP address and the one or more interface IP address each interface IP address it is corresponding whether effective mark.If first network

Corresponding priority be not it is minimum, then set minimum for the corresponding priority of the interface IP address, and send the 2nd RA
Message.It can prevent the repetition of the 2nd RA message from sending in this way.
For example, the interface IP address 1 and interface IP address 2 of second network equipment that first network equipment is locally stored are highest
Priority.First network equipment has sent the first RA message for carrying the interface IP address 1 and interface IP address 2 within the period 1.Second
The network equipment determines that interface IP address 1 is invalid, interface IP address 2 effectively, is then set to first network after receiving the first RA message
Standby to reply confirmation message, which carries interface IP address 1 and the invalid mark of interface IP address 1, interface IP address 2 and interface
Location 2 effectively identifies.First network equipment is set as minimum after receiving the confirmation message, by the priority of interface IP address 1,
The priority of interface IP address 2 is constant, and sends the 2nd RA message, invalid to notice interface IP address 1 in time.Within the period 2, interface
Address 1 is still invalid, then first network equipment and second network equipment can repeat the movement in the above-mentioned period 1, sends at this time
The 2nd RA message there is no any effect because it is invalid to have noticed interface IP address within the period 1.So in this example, only
It (is not received in predetermined period meeting above-mentioned two condition and is used to indicate the effective confirmation message of the interface IP address and described
The corresponding priority of interface IP address be not it is minimum, the interface IP address is effective before priority is not minimum explanation) when, just will
The corresponding priority of the interface IP address is set as minimum, and sends the 2nd RA message, can prevent the 2nd RA message in this way
It repeats to send, reduces the message amount in network.
If in addition, this method can also include: received in predetermined period be used to indicate the interface IP address it is effective and
The corresponding priority of the interface IP address be it is minimum, then improve the corresponding priority of the interface IP address.
The corresponding priority of interface IP address be it is minimum, it may be considered that before the period interface IP address be it is invalid,
And after receiving and being used to indicate the effective confirmation message of the interface IP address, then the priority of the interface IP address can be improved,
In this way first network equipment the next period send the first RA message when, the first RA message carry the interface IP address it is excellent
First grade is not just minimum.Host, can be using the interface IP address as the alternative of default route after receiving the first RA message.
The present embodiment, first network equipment send the interface IP address for carrying second network equipment to second network equipment
The first via makes second network equipment after receiving the first RA message by notice message RA message, determines that interface IP address is effective
Interface IP address when, to first network equipment transmission be used to indicate the effective confirmation message of interface IP address, if first network equipment
It is not received in predetermined period and is used to indicate the effective confirmation message of interface IP address, then the interface IP address of second network equipment may
It changes or fails, set minimum for the corresponding priority of interface IP address at this time, such first network equipment is next
Period send the first RA message carry the corresponding priority of the interface IP address be it is minimum, host receives the first network and sets
It is standby then the interface IP address to be selected as default route after the first RA message that the next period sends, while being sent to host
2nd RA message, the 2nd RA message is unavailable for notification interface address, and host is enable to perceive second network equipment in time
The interface IP address it is invalid, it is not necessary to can just know that the interface IP address is invalid by the first RA message until the next period, host
