VRRP is a kind of protocol for error tolerance, and the set of router that can undertake gateway function is joined in backup group by it, forms a virtual router. Router in VRRP backup group, according to priority, elects active router and undertakes gateway function, and other routers are as standby router. When active router breaks down, standby router replaces active router to be continued to fulfil gateway responsibility, thus the main frame ensured in LAN communicates with external network incessantly. Virtual router has Internet Protocol, and (English: InternetProtocol is called for short: IP) address, is called virtual ip address. The IP address of this virtual router only need to be set to the next-hop ip address of the default route of main frame by the main frame in LAN so that virtual router becomes default gateway, it is possible to communicated by default gateway and external network.

Router A, B, C form a virtual router, described virtual router is set to default gateway by the main frame 1,2,3 in LAN, communicated by this default gateway and external network, wherein, in described virtual router, the highest router A of priority, as active router, undertakes gateway function, and all the other two router B and C are as standby router. When router A breaks down, then router B and the C being in Status of Backups will elect the active router made new advances according to priority, and the active router newly selected provides route service by continuing to the main frame in LAN. One router can add multiple VRRP backup group, different VRRP backup groups can there is identical priority, such as: router A, B, C are added simultaneously to VRRP backup group 1 (corresponding virtual router 1), VRRP backup group 2 (corresponding virtual router 2) and VRRP backup group 3 (corresponding virtual router 3), at VRRP backup group 1, in VRRP backup group 2 and VRRP backup group 3, router A is all as active router, and router B and C is all as standby router.

In implementing, described the first router can obtain the competition message that multiple VRRP backup group sends respectively, and each competition message includes sending the virtual ip address that the VRRP backup group of described competition message is corresponding; According to the competition message that the plurality of VRRP backup group sends respectively, the plurality of VRRP backup group is aggregated on the appointment VRRP backup group in the plurality of VRRP backup group. Specifically, when the plurality of VRRP backup group includes identical router, the plurality of VRRP backup group just can be aggregated on the appointment VRRP backup group in the plurality of VRRP backup group by described the first router. The plurality of VRRP backup group is aggregated on the appointment VRRP backup group in the plurality of VRRP backup group, specifically refers to the operation performed respectively by the router in the plurality of VRRP backup group to be needed by the described router centralized operation specified in VRRP backup group.
Optionally, it is possible to obtain user configured binding information, described binding information includes multiple VRRP backup group virtual ip address corresponding respectively and specifies the virtual ip address of VRRP backup group; According to described binding information, the plurality of VRRP backup group is aggregated on the appointment VRRP backup group in the plurality of VRRP backup group.
Such as: as shown in Figure 3, router A, router B and router C are the gateway device on same VLAN or same interface link, this VLAN or interface link exist 100 using router A as the VRRP backup group of active router, the virtual ip address that these 100 VRRP backup groups are corresponding respectively is 1.1.1.1/24～1.1.100.1/24, it is possible to using VRRP backup group corresponding for virtual ip address 1.1.1.1/24 as specifying VRRP backup group. In embodiments of the present invention, virtual ip address (1.1.2.1/24～1.1.100.1/24) corresponding for other VRRP backup groups can be added in the described protocol massages specifying VRRP backup group to send, such that it is able to multiple VRRP backup groups are aggregated on the appointment VRRP backup group in the plurality of VRRP backup group.
S202, described the first router sends the first protocol massages of information carrying all VRRP backup groups being active router with described the first router to described other routers specified in VRRP backup group, so that other routers described determine the duty in described other routers each VRRP backup group in the plurality of VRRP backup group respectively according to described first protocol massages, the information of each VRRP backup group includes described the first router priority in described VRRP backup group and virtual ip address corresponding to described VRRP backup group.
In implementing, it is possible to obtain the prefixed time interval sending described first protocol massages from described first protocol massages; According to the described prefixed time interval sending described first protocol massages, send the first protocol massages of information carrying all VRRP backup groups being active router with the first router to other routers specified in VRRP backup group. Owing to the information of all VRRP backup groups is carried in same described first protocol massages specifying VRRP backup group to send, and by being sent to other routers as the first router of active router, the first router need not send protocol massages respectively for each VRRP backup group, thus saving the quantity sending protocol massages.
It should be noted that, owing to the first router sends, as the active router specifying VRRP backup group, the first protocol massages of information carrying all VRRP backup groups being active router with the first router, accordingly, it would be desirable to suppress each router to send protocol massages as the active router of other VRRP backup groups. Specifically, it is possible to close other VRRP backup groups for regularly sending the intervalometer of protocol massages to suppress.
Additionally, the second router receives the first protocol massages of information carrying all VRRP backup groups being active router with the first router that the first router sends, according to described first protocol massages, it is determined that described the second router duty in each VRRP backup group. concrete, after the second router receives described first protocol massages that the first router sends, the priority carried in more described first protocol massages of the second router, the i.e. priority of described the first router, whether higher than the second router priority in the plurality of VRRP backup group, if the priority carried in described first protocol massages is higher than described the second router priority in the plurality of VRRP backup group, then keep the second router state in the plurality of VRRP backup group, if the priority carried in described first protocol massages is lower than the second router priority in the plurality of VRRP backup group, then revise the duty of the second router, under contention mode, this the second router replaces the first router active router as the plurality of VRRP backup group. wherein, same router has identical priority in the multiple VRRP backup groups that can be polymerized.
Additionally, the interval that the first router is sent described first protocol massages by the second router is monitored; If the interval that the first router sends described first protocol massages exceedes prefixed time interval, it is determined that the first router is in abnormal operation; When determining that the first router is in the priority that abnormal operation and the second router priority in described each VRRP backup group is higher than other routers, when determining that described the first router is in the priority that abnormal operation and the described the second router priority in described each VRRP backup group is higher than other routers, determine the active router that described the second router is described each VRRP backup group, after, send the second protocol message of information carrying all VRRP backup groups being active router with the second router to other routers.
Further, from described first protocol massages, obtain the virtual ip address that described each VRRP backup group is corresponding respectively; According to the virtual ip address that described each VRRP backup group is corresponding respectively, multiple VRRP backup groups are aggregated on the appointment VRRP backup group in the plurality of VRRP backup group; The second protocol message of information carrying all VRRP backup groups being active router with described the second router is sent to described other routers specified in VRRP backup group.
Such as: as shown in Figure 3, when router B or router C monitor router A send protocol massages interval exceed prefixed time interval, then confirm that router A is in abnormal operation, now, if the priority that router B is in each VRRP backup group is higher than router C, then router B competition is the active router of the plurality of VRRP backup group, router B obtains the information of all VRRP backup groups from router A the first protocol massages sent, and the second protocol message of information carrying all VRRP backup groups being active router with described the second router is sent to other routers specified in VRRP backup group, the information of this VRRP backup group includes the virtual ip address (1.1.2.1/24～1.1.100.1/24) that each VRRP backup group is corresponding.
It should be noted that when detecting that interface link is in abnormality or specifies the polymerizable functional of VRRP backup group to be closed, it is possible to make each VRRP backup group in multiple VRRP backup group send protocol massages respectively according to prior art. Concrete, specify the router in VRRP backup group to receive and close the order specifying VRRP backup group, the prefixed time interval specifying VRRP backup group to send protocol massages is reset to 0, and allow this router to send protocol massages as the active router of arbitrary VRRP backup group, so that other VRRP backup group returns to the working method of prior art.
In embodiments of the present invention, when the multiple VRRP backup groups on same VLAN or same interface link are respectively using the first router as active router, the plurality of VRRP backup group is aggregated on the appointment VRRP backup group in the plurality of VRRP backup group by the first router; The first router sends the first protocol massages of information carrying all VRRP backup groups being active router with the first router to other routers specified in VRRP backup group, so that other routers described determine described other routers duty in each VRRP backup group respectively according to described first protocol massages. The embodiment of the present invention the first router need not send protocol massages for each VRRP backup group respectively, therefore, it is possible to reduce the transmission times of protocol massages, reduces the resource consumption of router.
