VRRP is a kind of selection agreement, by its realization, the set of router in LAN can be organized as one
Platform virtual router, this virtual router can have the virtual ip address of oneself, such as, for 1.1.1.254.
This group router can be referred to as VRRP backup group.In VRRP backup group, can be elected by VRRP
Mechanism, elects a router as virtual router master, i.e. this virtual router master undertakes forwarding task, its
Its router is then standby router, and configures identical standby respectively on virtual router master and standby router
Part group configuration information, this backup group configuration information can include virtual ip address, such as, 1.1.1.254.
The default route next hop address of self can be set to this virtual router by the main frame in LAN
Virtual ip address, thus, the main frame in LAN can be realized and other network by this virtual router,
Such as the Internet communicates.When the virtual router master in VRRP backup group breaks down, can pass through
Election mechanism and timeout mechanism, from standby router, re-elect out a router as new master control road
By device so that this virtual router can continue the main frame in LAN provides route service.
Owing to the network environment of network is complicated and changeable, join when needing the router in VRRP backup group
When putting renewal, i.e. revise the backup group configuration information of this locality, such as, revise virtual ip address, it is likely that go out
Existing backup group configuration information amendment mistake, such as, the backup group configuration letter of standby router and virtual router master
Cease inconsistent.In order to avoid in this case, causing network to shake, and reality now due to configuration error and
When causing Network Abnormal, which route of the reason that prompting user network is abnormal effectively, such as prompting user
The configuration of device goes wrong, and the application provides the method and device that a kind of VRRP backup group state switches.
Following Fig. 1, it is shown that the embodiment of the present application realizes the application of the method for VRRP backup group state switching
Scene schematic diagram.Fig. 1 includes: main frame 11, switch 12, server 13, router 14 to route
Device 16, wherein, main frame 11 is positioned at LAN, it is to be understood that in actual applications, this LAN
An interior more than main frame, illustrates as a example by only including a main frame in LAN, the application in the application
Without limitation；Switch 12 for the data transmission being responsible between each router, and main frame 11 with
Data transmission between server 13；Server 13 is positioned at the Internet；Router 14 to router 16
Belong to same VRRP backup group, i.e. router 14 to router 16 and constitute a virtual router 17,
It is understood that the router number in VRRP backup group can not be 3, only with VRRP in the application
Illustrating as a example by comprising 3 routers in backup group, the application is without limitation.
In the application scenarios figure shown in above-mentioned Fig. 1, it is assumed that the virtual ip address of virtual router 17 is
1.1.1.254, then self the default route next hop address on main frame 11 is set to this virtual ip address, with reality
Existing main frame 11, by this virtual router 17, communicates with the server 13 in the Internet.And router
All being configured with backup group configuration information on 14 to router 16, this backup group configuration information can include virtual IP address
Address 1.1.1.254, it is also possible to be respectively every configuration of routers priority and pattern, it is generally the case that for
The priority of every configuration of routers also differs, and such as, the priority of router 14 to router 16 depends on
Secondary it is respectively 200,100,50, and the pattern of every router is contention mode.Configure VRRP standby
After part group, can be according to VRRP election mechanism, by router the highest for priority, such as, router
14 elections are virtual router master, then, other router in this VRRP backup group, such as, router
15 and router 16 be then standby router.
When router in VRRP backup group shown in Fig. 1 is carried out the amendment of backup group configuration information, when
When the inconsistent situation of the backup group configuration information of standby router and virtual router master occurs, can be used this
The method of application embodiment VRRP backup group state switching, following Fig. 2, illustrate the application VRRP
One embodiment flow chart of the method for backup group state switching, this embodiment is with the standby router in Fig. 1
As a example by 15, illustrate.
Step S201: the notice report sent according to the described virtual router master received when described standby router
Literary composition, described notification packet carries the backup group configuration information of configuration on described virtual router master, determines this locality
When backup group configuration information in backup group configuration information and described notification packet is inconsistent, by oneself state by
Resting state switches to malfunction.
Such as, virtual router master 14, every default notification time, i.e. send a notification packet, this leads to
Accusing the backup group configuration information that can carry virtual router master 14 in message, this backup group configuration information can wrap
Include virtual ip address, such as 1.1.1.254.
In the present embodiment, it is assumed that have modified the backup group configuration information of standby router 15, by its virtual IP address
1.1.1.253 is revised as by 1.1.1.254 in address.So, virtual router master is received when standby router 15
After 14 notification packets sent, can detect that the backup group configuration information of this locality carries in this notification packet
Backup group configuration information inconsistent, now, standby router 15 can be by the state of self by resting state
Switch to malfunction, to represent that the VRRP backup group configuration of self is likely to occur mistake, such as, with master
The backup group configuration information of control router 14 is inconsistent.
Due to, when standby router detects that the configuration of self backup group is likely to occur mistake, switch to fault
State, not major state or holding resting state are constant, thus, it is not result in VRRP backup group
There is multiple stage virtual router master simultaneously, network will not be caused to shake；And can realize by malfunction effective
Ground prompting this router of user is likely to occur configuration error so that causing Network Abnormal due to configuration error
Time, user can determine the reason of Network Abnormal quickly, to repair network quickly, it is to avoid break for a long time
Net, results in greater loss to user.
Step S202: when the described router of malfunction that is in is according to the described notification packet received, really
When determining the backup group accordant configuration information in local backup group configuration information and described notification packet, by self
State is switched to resting state by malfunction.
Assume have modified the backup group configuration information of the router 15 being in malfunction, such as, it is empty
Intend IP address and be revised as 1.1.1.254 by 1.1.1.253.So, master control road is continued to when router 15
The described notification packet sent by device 14, can detect backup group configuration information and this notification packet of this locality
In the backup group accordant configuration information that carries, then, router 15 can be by the state of self by malfunction
Switch to resting state.
The method of application the present embodiment, when standby router detects local backup group configuration information and master control road
By the backup group configuration information of device inconsistent time, oneself state is switched to malfunction, later, detection
During to the backup group accordant configuration information of local backup group configuration information and virtual router master, oneself state is extensive
It is resting state again, such that it is able to avoid VRRP backup group exists a more than virtual router master simultaneously,
Network is caused to shake；Can also realize, when causing due to configuration error network to occur abnormal, pass through road
By the malfunction of device, can effectively point out user, make user confirm quickly to cause the former of Network Abnormal
Cause, it is to avoid Network Abnormal for a long time, results in greater loss to user.
On the basis of above-mentioned embodiment illustrated in fig. 2, following Fig. 3, illustrate the application VRRP backup group
Another embodiment flow chart of the method for state switching, describes in the embodiment shown in this Fig. 3 and is in event
Oneself state is switched to the another kind of situation of resting state, and state switching afterwards by the router of barrier state
Processing procedure, comprise the following steps:
Step S301: the notice report sent according to the described virtual router master received when described standby router
Literary composition, described notification packet carries the backup group configuration information of configuration on described virtual router master, determines this locality
When backup group configuration information in backup group configuration information and described notification packet is inconsistent, by oneself state by
Resting state switches to malfunction.
The associated description of this step may refer to the associated description of step S201 in above-described embodiment, at this no longer
It is described in detail.
Step S302: described standby router after oneself state is switched to malfunction by resting state,
Fault time-out time is set.
In the present embodiment, malfunction can be switched to for described by resting state according to default algorithm
Router, such as, router 15, a fault time-out time is set, such as, draws according to equation below
Fault time-out time:
Fault time-out time=3* notification time+(255-priority)/255 seconds, wherein, notification time is main
Control router sends the interval time of notification packet, the most under normal circumstances, virtual router master to standby router
I.e. a notification packet is sent to standby router every this notification time；Priority is oneself of this router
Body priority.
It is understood that above-mentioned formula is only a kind of example calculating fault time-out time, in actual application,
Other algorithms can also be used to calculate, and the application is without limitation.
Step S303: described in be in the router of malfunction, in described fault time-out time, if not connecing
Receive described notification packet, then oneself state is switched to resting state by malfunction.
In the present embodiment, if described in be in the router of malfunction, such as, router 15, described therefore
Barrier time-out time in, do not receive the notification packet that virtual router master is sent yet, can by oneself state by
Malfunction switches to resting state again.Now, the backup group configuration information of this router 15 still with currently
The backup group configuration information of virtual router master 14 inconsistent.
Step S304: described router, after oneself state is switched to resting state by malfunction, is arranged
The standby time-out time.
In the present embodiment, the algorithm can preset according to another, switched to standby shape for described by malfunction
The router of state, such as router 15, arrange a standby time-out time, and this standby time-out time can be by
Calculate according to equation below:
Standby time-out time=1+ (255-priority)/255 seconds.
It is understood that above-mentioned formula is only a kind of example calculating the standby time-out time, in actual application,
Other algorithms can also be used to calculate, and the application is without limitation.
Arranging the purpose of this standby time-out time is, postpones this router 15 and again carries out the time of state switching,
So that in the case of virtual router master 14 fault, priority is relatively low, and the router being in resting state can
To have an opportunity, oneself state being switched to major state, the such as priority of router 16 is less than router 15
Priority, and router 16 is currently at resting state, then router 16 is determining current master control road
During by device 14 exception, oneself state can be switched to major state, i.e. router 16 becomes master control route
Device, sends notification packet.Now, after router 15 receives the notification packet that virtual router master is sent,
Again oneself state can be switched to malfunction by resting state, it is possible to continue according to step S302 institute
State, fault time-out time is set.Thus, effectively prevent the router of configuration error, such as, router
15 become virtual router master, cause Network Abnormal.
Step S305: described in be in the router of resting state, within the described standby time-out time, if not connecing
Receive described notification packet, then oneself state is switched to major state by resting state.
In the present embodiment, if the described router being switched to resting state by malfunction, standby super at this
Time the time in, do not receive yet virtual router master send notification packet time, then by oneself state by standby shape
State switches to major state.
For example, it is assumed that current virtual router master 14 fault, it is impossible to send notification packet, and router 16 is also
Fault, it is impossible to oneself state is switched to major state, then switched to resting state by malfunction
Router 15, then, within this standby time-out time, do not receive the notification packet that virtual router master sends, then
By resting state, oneself state can be switched to major state, now, router 15 is virtual router master.
The most such as, as it has been described above, in virtual router master 14 fault, after router 16 becomes virtual router master,
Now router 15 is in malfunction, and includes fault time-out time.If assuming current virtual router master 16
Also break down, then router 15 can perform step S303, will switch to resting state by oneself state,
Follow-up, step S304 can be continued executing with, until, router 15, within the described standby time, receives not yet
The notification packet sent to virtual router master, then router 15 oneself state the most at last switches to major state.
In this case, due to current virtual router master, such as, router 15 configuration error, will draw
Play Network Abnormal.Now, user can find to cause the reason of Network Abnormal in time, and such as, user is permissible
Check the state switching record of router, be may determine that the oneself state of current virtual router master by this record
It is by malfunction, switches to resting state, finally because of standby time-out time time-out, just switch to master control shape
State, so that it is determined that current virtual router master configuration error, then user can repair network quickly, it is to avoid
Long-time suspension, results in greater loss to user.
Additionally, when the state of all-router in VRRP backup group all switches to major state, such as,
When switch 12 fault, router 14 to router 16 does not all receive the notice that virtual router master sends
Message, the most all switches to major state by oneself state.Follow-up, when switch 12 recovers normal, then may be used
With according to election mechanism, re-elect out the highest router of priority as virtual router master.Such as, road
Be virtual router master by device 14, then virtual router master 14 continuation sends and carries self backup group configuration information
Notification packet, when other routers, such as router 15, according to the notification packet received, detect this
When ground backup group configuration information is inconsistent with the configuration information in notification packet, then by oneself state by master control shape
State switches to malfunction, and router 16, according to the notification packet received, local backup group detected
Configuration information and the accordant configuration information in notification packet, then switched to standby by oneself state by major state
State.
The method of application the present embodiment, when standby router detects local backup group configuration information and master control road
By the backup group configuration information of device inconsistent time, oneself state is switched to malfunction, such that it is able to avoid
VRRP backup group exists a more than virtual router master simultaneously, causes network to shake；And when Network Abnormal,
Can be by the malfunction of router, prompting user causes the reason of Network Abnormal effectively so that user
Network problem can be repaired quickly, thus avoid long Network Abnormal, user be caused bigger
Loss.
On the basis of above-mentioned Fig. 2 with embodiment illustrated in fig. 3, following Fig. 4, illustrate the application VRRP
Another embodiment flow chart of the method for backup group state switching, in the embodiment shown in this Fig. 4,4 is detailed
Describe described in be in the router of malfunction be how to carry out oneself state switching, including following step
Rapid:
Step S401: the notice report sent according to the described virtual router master received when described standby router
Literary composition, described notification packet carries the backup group configuration information of configuration on described virtual router master, determines this locality
When backup group configuration information in backup group configuration information and described notification packet is inconsistent, by oneself state by
Resting state switches to malfunction.
The detailed description of this step may refer to the associated description of step S201 in above-described embodiment, at this no longer
It is described in detail.
Step S402: described standby router after oneself state is switched to malfunction by resting state,
Fault time-out time is set.
The detailed description of this step may refer to the associated description of step S302 in above-described embodiment, at this no longer
It is described in detail.
