Detailed description of the invention
Understandable for enabling the above-mentioned purpose of the application, feature and advantage to become apparent from, real with concrete below in conjunction with the accompanying drawings
The application is described in further detail by mode of executing.
See Fig. 1 and show the network environment schematic diagram of IRDP of the prior art, specifically include: main frame (host A and master
Machine B), inner exchanging network, network equipment A (Router A), network equipment B (Router B) and outer net (outer net 1 and outer net
2), wherein, network equipment A supports IRDP function, and network equipment B does not support IRDP function, it is therefore desirable to network equipment A is as generation
Network equipment B interface address is noticed by reason.
The proposition network equipment A of present inventor's innovation sends a RA of the interface IP address carrying network equipment B
Message, so that network equipment B is after receiving a RA message, determines when this interface IP address is valid interface, to network equipment A
Transmission is used for indicating the effective confirmation message of this interface IP address, if not receiving confirmation message in predetermined period, then by interface ground
Priority corresponding to location is set to minimum, and sends the 2nd RA message, and the 2nd RA message is used for notifying that this interface IP address can not
With, so that main frame can be the most effective with the address of sensing network equipment B.
It should be noted that the network equipment can be switch or router, it is also possible to for other equipment, to this this Shen
Please be not particularly limited.
Based on above-mentioned networking schematic diagram, with reference to Fig. 2, it is shown that a kind of network equipment ground of one of them embodiment of the application
The flow chart of location notifying method.Described method is applied to first network equipment, and described first network equipment is for agency's the second net
Network equipment notices the interface IP address of described second network equipment, and in the present embodiment, the method specifically includes:
Step 201: send a RA message of the interface IP address carrying described second network equipment, so that described second
The network equipment, after receiving a described RA message, determines when described interface IP address is effective interface IP address, to described
One network equipment sends and is used for indicating the effective confirmation message of described interface IP address.
Wherein, a RA message is to enable, by first network equipment, the RA message that the interface of IRDP sends, should
Oneth RA message is used for noticing the interface IP address of second network equipment, the priority of this interface IP address and ageing time etc., and
And the oneth RA message be that periodically broadcast or multicast are transmitted.
Step 202: if not receiving for indicating the effective confirmation message of described interface IP address in predetermined period, then by institute
Stating priority corresponding to interface IP address and be set to minimum, and send the 2nd RA message, described 2nd RA message is used for noticing described
Interface IP address is unavailable.
Wherein, described confirmation message carries interface IP address and interface IP address the most effectively identifies.
Further, a RA message may carry one or more interface IP addresses of second network equipment, when first
When RA message carries one or more interface IP address of second network equipment, do not receive for indicating interface IP address effectively to confirm
Message includes situations below:
Situation one: the whole DOWN of one or more interface IP addresses of second network equipment carried when a RA message or
Fault, second network equipment can not receive a RA message, then first network equipment will not receive in predetermined period
Confirmation message, then it is assumed that one or more interface IP address void in whole of second network equipment carried in a RA message.
Situation two: the second network equipment receives a RA message, it is judged that carries in a RA message is one or more
Interface IP address is the most effective, then to first network device replied confirmation message, carries this one or more in this confirmation message
Corresponding the most effectively the identifying of each interface IP address in interface IP address and this one or more interface IP addresses.If first network
Equipment receives confirmation message in predetermined period, then according to the mark that the interface IP address carried in confirmation message is corresponding with interface IP address
Know, confirm in these one or more interface IP addresses, which interface IP address is effective, and which interface IP address is invalid.If first network equipment
Confirmation message is not received, then it is assumed that the one or more of second network equipment carried in a RA message connect in predetermined period
Port address void in whole.
It should be noted that in situation two, although first network equipment receives confirmation message, if but in this confirmation message
Certain interface IP address corresponding mark instruction be that this interface IP address is invalid, then be equivalent to first network equipment and do not receive finger
Show the effective confirmation message of this interface IP address.
Wherein, interface IP address is unavailable includes but not limited to that interface IP address is invalid and interface IP address change etc..2nd RA
Message is not periodically to send, only when not receiving in predetermined period for indicating the effective confirmation message of interface IP address
Time, just can send the 2nd RA message.
In one example, described interface IP address can be noticed in the following manner unavailable:
First kind of way: when carrying described interface IP address and corresponding aging of described interface IP address in described 2nd RA message
Between, described ageing time is 0, after such main frame receives the 2nd RA message, finds that the ageing time in the 2nd RA message is 0, then
Delete this interface IP address, just will not re-use this interface IP address.
The second way: described 2nd RA message carries described interface IP address and priority corresponding to described interface IP address,
Owing to, before sending the 2nd RA message, priority corresponding for this interface IP address being set to minimum, therefore the 2nd RA
The priority that this interface IP address of carrying in message is corresponding is minimum.After so main frame receives the 2nd RA message, find that this connects
The priority that port address is corresponding is minimum, then will not re-use this interface IP address.
In one example, if not receiving for indicating the effective confirmation message of described interface IP address in predetermined period,
Then priority corresponding for described interface IP address is set to minimum, and sends the 2nd RA message, specifically include:
If not receiving in predetermined period for indicating the effective confirmation message of described interface IP address and described interface IP address
Corresponding priority is not minimum, then be set to minimum by priority corresponding for described interface IP address, and send described 2nd RA
Message.So be possible to prevent the 2nd RA message repeats transmission.
Such as, interface IP address 1 and the interface IP address 2 of second network equipment that first network equipment is locally stored is the highest
Priority.Within the cycle 1, first network equipment have sent the RA message carrying this interface IP address 1 and interface IP address 2.Second
The network equipment, after receiving a RA message, determines that interface IP address 1 is invalid, and interface IP address 2 effectively, then sets to first network
Standby replying confirmation message, this confirmation message carries interface IP address 1 and the invalid mark of interface IP address 1, interface IP address 2 and interface ground
Location 2 effectively identifies.The priority of interface IP address 1, after receiving this confirmation message, is set to minimum by first network equipment,
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 cycle 2, interface
Address 1 is the most invalid, then first network equipment and second network equipment can repeat the action in the above-mentioned cycle 1, now send
The 2nd RA message there is no any effect, because it is invalid to have noticed interface IP address within the cycle 1.So in this example, only
(i.e. do not receive in predetermined period for indicating the effective confirmation message of described interface IP address and described meeting above-mentioned two condition
The priority that interface IP address is corresponding is not minimum, and priority is not effective for this interface IP address before minimum explanation) time, just general
The priority that described interface IP address is corresponding is set to minimum, and sends the 2nd RA message, is so possible to prevent the 2nd RA message
Repeat to send, reduce the message amount in network.
It addition, the method can also include: if receive in predetermined period for indicating described interface IP address effective and
The priority that described interface IP address is corresponding is minimum, then improve the priority that described interface IP address is corresponding.
The priority that interface IP address is corresponding is minimum, then it is believed that before this cycle this interface IP address be invalid,
And receiving after indicating the effective confirmation message of this interface IP address, then the priority of this interface IP address can be improved,
So when first network equipment sends a RA message in the next cycle, this interface IP address that a RA message carries excellent
First level is not the most minimum.Main frame, can be using alternative as default route of this interface IP address after receiving a RA message.
The present embodiment, first network equipment carries the interface IP address of second network equipment to the second network equipment transmission
The first via, by notice message RA message, makes second network equipment after receiving a RA message, determines that interface IP address is effective
Interface IP address time, to first network equipment send be used for indicating the effective confirmation message of interface IP address, if first network equipment
Do not receive for indicating the effective confirmation message of interface IP address in predetermined period, then the interface IP address of second network equipment may
Changing or lost efficacy, being now set to minimum by priority corresponding for interface IP address, such first network equipment is next
The priority that this interface IP address of carrying of a RA message that cycle sends is corresponding is minimum, and main frame receives this first network and sets
For this interface IP address then will not be selected after the RA message that the next cycle sends as default route, send to main frame simultaneously
2nd RA message, described 2nd RA message is unavailable for notification interface address, makes main frame energy perception second network equipment in time
This interface IP address invalid, it is not necessary to wait until that the next cycle just can know that this interface IP address is the most invalid by a RA message, main frame
Select other interface IP addresses as default route after receiving the 2nd RA message, normally E-Packet.
