Refer to Fig. 1, be a kind of vrrp group-network construction figure.As shown in figure 1, the interface 11 of router 1 and connecing of router 2
Mouth 21 accesses Intranet by switch 1, and the interface 12 of router 1 and the interface 22 of router 2 pass through switch 2 accessing external network,
Router 1 and router 2 all can execute the routing function between Intranet and outer net.In correlation technique, can be by based on vrrp
Router 1 and router 2 are added in same vrrp backup group and provide routing function for Intranet, based on the election of vrrp agreement,
Can determine that a certain router is the primary route device (master router) in this vrrp backup group, another router is should
Standby router (backup router) in vrrp backup group.When primary route device breaks down, standby router is permissible
Take over primary route device and Intranet offer routing function is provided.
Please continue to refer to Fig. 1, in correlation technique, router 1 and router 2 can also be added to two vrrp backup groups
In, such as: the vrrp id of interface 11 and interface 21 can be disposed as 1 by user, so that router 1 and router 2 are incorporated as
Intranet provides the vrrp backup group 1 of routing function；And the vrrp id of interface 12 and interface 22 is disposed as 2, so that router
1 and router 2 be incorporated as outer net provide routing function vrrp backup group 2.
Assume that user is that interface 11 and interface 12 are provided with higher priority, and be interface 21 and interface 22 is provided with relatively
Low priority.Role's election is carried out based on vrrp agreement it may be determined that based on role in vrrp backup group 1 for the router 1
With router, role in vrrp backup group 1 for the router 2 is standby router；Angle in vrrp backup group 2 for the router 1
Color is also primary router, and role in vrrp backup group 2 for the router 2 is also standby router, and router 1 can be by connecing
Mouth 11 and interface 12 carry out message forwarding, are Intranet and outer net execution routing function.However, when same router is at this two
When role in vrrp backup group is different, may result in network service abnormal.For example: when interface 11 breaks down, triggering
Role elects, and role in vrrp backup group 1 for the router 1 switches to standby router by primary route device, and router 2 exists
Role switching in vrrp backup group 1 is primary router.But now role in vrrp backup group 2 for the router 2 is still standby
With router, then router 1 still can receive message from outer net by interface 12, yet with interface 11 fault, road
Can be by these packet loss, thus leading to communication abnormality by device 1.
In correlation technique, the role in each vrrp backup group being located at it in order to ensure same router is identical, route
Device 1 can monitor interface 11, if interface 11 fault, can trigger vrrp backup group 1 and re-start role's election, make router
2 roles in vrrp backup group 1 are changed into primary route device.Meanwhile, router 1 can also reduce it in vrrp backup group 2
Priority, with trigger vrrp backup group 2 re-start role election, make role in vrrp backup group 2 for the router 1 also by
Primary route device switches to standby router.In these cases, because the role's election process in each vrrp backup group is mutual
Mutually independent, role in vrrp backup group 1 for the router 1 may be led to have turned into standby router, and vrrp backup group 2 is still
Undone role's election, role in vrrp backup group 2 for the router 1 is still the situation of primary router, in this situation
Lower router 1 still can abandon the message from outer net, thus leading to network service abnormal.
Refer to Fig. 2, be a kind of flow chart of the vrrp state synchronization method shown in the application one exemplary embodiment, should
Method can apply to the network equipment, and the described network equipment adds multiple different vrrp backup groups, the plurality of vrrp backup
Group include a main vrrp backup group and multiple from vrrp backup group.The method may comprise steps of:
Step 201: when role in all vrrp backup groups for this equipment is host apparatus, if belonging to described master
The interface fault of vrrp backup group, then trigger role's election of described main vrrp backup group, so that originally setting according to default strategy
Standby role in described main vrrp backup group switches to stand-by equipment by host apparatus.
In the present embodiment, when when this equipment, the role in all vrrp backup groups is host apparatus, if belonged to
The interface fault of described main vrrp backup group, then this equipment can be according to the angle of the default strategy described main vrrp backup group of triggering
Color is elected, so that role in described main vrrp backup group for this equipment switches to stand-by equipment by host apparatus.Described genus
Interface fault in described main vrrp backup group may include that described interface is in down state, the ip address of described interface with
The ip address of the virtual router of described main vrrp backup group composition not in the same network segment, with the ip address of described interface conjunctionn not
Up to situations such as.
Wherein, when described interface is in the ip address of down state or described interface and described main vrrp backup group composition
Not in the same network segment, this equipment can close described interface for the ip address of virtual router, and then it is standby to trigger described main vrrp
Role's election of part group；And when unreachable with the ip address of described interface conjunctionn, for example: the remote host connecting when up-link
Ip address unreachable when, this equipment can reduce its priority in described main vrrp backup group, so trigger described master
Role's election of vrrp backup group.
Step 202: when role in described main vrrp backup group for this equipment switches to stand-by equipment by host apparatus,
Role the described backup group from vrrp for this equipment is also switched to stand-by equipment by host apparatus.
In the present embodiment, when this equipment, the role in described main vrrp backup group switches to standby setting by host apparatus
When standby, it role the described backup group from vrrp also can be switched to stand-by equipment by host apparatus by this equipment, so that
This equipment is identical with the role from vrrp backup group in main vrrp backup group.Described do not need to carry out role from vrrp backup group
Election, each equipment follows role switching in described main vrrp backup group for this equipment in the role the described backup group from vrrp
And switch.
In an optional embodiment, when this equipment, the role in described main vrrp backup group is switched by stand-by equipment
During for host apparatus, it role the described backup group from vrrp also can be switched to primary setting by stand-by equipment by this equipment
Standby.
In another optional embodiment, when this equipment, the role in all vrrp backup groups is host apparatus

To trigger role's election of described main vrrp backup group according to described default strategy, so that this equipment is standby in described main vrrp
Role in part group switches to stand-by equipment by host apparatus, is cut in each role from vrrp backup group with triggering this equipment
Change.Specifically, this equipment can reduce its priority in described main vrrp backup group, and then triggers described main vrrp backup
Role's election of group.
In another optional embodiment, when this equipment, the role the described backup group from vrrp is cut by host apparatus
When being changed to stand-by equipment, its priority modification the described backup group from vrrp can be 0 by this equipment, that is, minimum preferential
Level, to guarantee role the described backup group from vrrp for this equipment as stand-by equipment.In the same manner, when this equipment described from vrrp
When role in backup group switches to host apparatus by stand-by equipment, this equipment can be by it the described backup group from vrrp
Priority modification is 255, i.e. highest priority, to guarantee that role the described backup group from vrrp for this equipment sets for primary
Standby.

Still it is exemplified as example with aforementioned, router 1 and router 2 are in the vrrp backup group being incorporated as Intranet offer routing function
While 1, can also be incorporated as outer net provides the vrrp backup group 2 of routing function.User can be interface 11 and interface 12 sets
Put higher priority, and be interface 21 and interface 22 arranges relatively low priority, then after role's election is carried out based on vrrp,
Role in vrrp backup group 1 and vrrp backup group 2 for the router 1 is host apparatus, and router 2 is in vrrp backup group 1 He
Role in vrrp backup group 2 is stand-by equipment.It is assumed that user by vrrp backup group 1 arrange based on vrrp backup group, will
Vrrp backup group 2 is set to from vrrp backup group.
Router 1 can monitor the interface 11 belonging to vrrp backup group 1, when interface 11 is in down state, router 1
With down interface 11, and then the role's election in vrrp backup group 1 can be triggered.After electing through role, router 1 is in vrrp
Role in backup group 1 switches to stand-by equipment by host apparatus, and router 2 role in vrrp backup group 1 set by standby
Standby switch to host apparatus.
Router 1 can also monitor the interface 12 belonging to vrrp backup group 2, when interface 12 is in down state, route
Device 1 can reduce its priority in vrrp backup group 1, and then triggers the role's election in vrrp backup group 1.Through angle
After color election, role in vrrp backup group 1 for the router 1 switches to stand-by equipment by host apparatus, and router 2 is standby in vrrp
Role in part group 1 switches to host apparatus by stand-by equipment.
When role in vrrp backup group 1 for the router 1 switches to stand-by equipment by host apparatus, router 1 is permissible
Its role in vrrp backup group 2 is also switched to stand-by equipment by host apparatus；When router 2 is in vrrp backup group 1
Role when host apparatus are switched to by stand-by equipment, router 2 can be by its role in vrrp backup group 2 also by standby
Equipment switches to host apparatus.
It is assumed that router 3 is also added in vrrp backup group 1 and vrrp backup group 2, but in router 3, not for
Vrrp backup group 1 and vrrp backup group 2 setting master slave relation.When role in vrrp backup group 2 for the router 2 is host apparatus
When, router 2 can send the notification packet of corresponding vrrp backup group 2 to router 1 and router 3, takes in this notification packet
With priority in vrrp backup group 2 for the router 2.Router 1, when receiving this notification packet, can not wherein be taken
The priority of band and priority in vrrp backup group 2 for the router 1.But router 3 is when receiving this notification packet, still
By the priority wherein carrying, the priority in vrrp backup group 2 is compared with router 3 for meeting, when the latter is higher than the former
When, router 3 can be seized as host apparatus in vrrp backup group 2, thus leading to same router in vrrp backup group 1 He
Role in vrrp backup group 2 is different.Therefore, based on being switched by stand-by equipment as role in vrrp backup group 2 for the router 2
When using equipment, its priority modification in vrrp backup group 2 can also be 255, to guarantee router 2 in vrrp backup group
Role in 2 is host apparatus.Corresponding, when router 1, the role in vrrp backup group 2 is switched to by host apparatus
During stand-by equipment, its priority modification in vrrp backup group 2 can also be 0, to guarantee router 1 in vrrp backup group
Role in 2 is stand-by equipment.
As seen from the above-described embodiment, when same router is added in multiple different vrrp backup groups, can be by it
In vrrp backup group based on the setting of vrrp backup group, and remaining vrrp backup group is set to from vrrp backup group.With
Correlation technique is compared, and described main vrrp backup group can carry out role's election based on vrrp, and described from vrrp backup group then not
Need to carry out role's election, this router follows it in described main vrrp backup group in the role the described backup group from vrrp
Role switching and switch, so that role in all vrrp backup groups for this router is consistent.In this case,
Role in main vrrp backup group for the same router can remain synchronous with the role from vrrp backup group, is net
