In the embodiment of the present invention, each other between first equipment and the second equipment of redundancy, set up many VRRP links: by heartbeat, set up a described VRRP link simultaneously, and, described the first equipment does transfer by the 3rd equipment and described the second equipment is set up described the 2nd VRRP link, by monitoring the activestandby state of the first equipment described in a described VRRP link and described the 2nd VRRP link and the second equipment, when a VRRP link occurs fault, make at the first equipment described in this faulty link and the second equipment during simultaneously for main equipment, judge the activestandby state in the VRRP link that the first equipment and the second equipment do not break down at another respectively, if two be master status in link, in faulty link, do not need to change the activestandby state of this equipment, otherwise, this equipment is switched to stand-by equipment, by the activestandby state of the equipment in this faulty link is switched, thereby avoid in master/slave device because of VRRP link occurs fault, and there is the two main phenomenon of two main equipments.
It should be noted that, in specific implementation process, described the first equipment is done to transfer by the 3rd equipment and described the second equipment is set up described the 2nd VRRP link, can comprise following several implementation:
(1) on the link of described the first equipment and described the second equipment and described the 3rd equipment connection, create respectively the 2nd VRRP LI(link interface) configuration, on described the 3rd equipment, create the local CCC(Circuit Cross Connect of corresponding described the 2nd VRRP LI(link interface) configuration, local circuit interconnection), by the VRRP message between the first equipment described in described CCC transparent transmission and described the second equipment.
As shown in Figure 3, on the VRRP2 link being connected with SR3 with SR2 at SR1 respectively, create interface configuration, on SR3, create the local CCC of corresponding VRRP2 LI(link interface) configuration, by the message transmitting on CCC transparent transmission VRRP2 link.
(2) between described the first equipment and described the second equipment, configuration, through the channel of described the 3rd equipment, makes described the 3rd equipment by described channel, directly the VRRP message between the first equipment and described the second equipment described in transparent transmission.
As shown in Figure 4, between SR1 and SR2, configure specified path through the channel of SR3, for example: LDP(Label Distribution Protocol, label distribution protocol), TE(Traffic Engineering, traffic engineering) form such as, the configuration of the upper establishment of SR3 the corresponding interface, not perception VRRP2 message on SR3, directly by the message transmitting on this channel transmitting VRRP2 link.
(3) between described the first equipment and described the 3rd equipment, set up a VRRP sublink, between described the second equipment and described the 3rd equipment, set up the 2nd VRRP sublink, a described VRRP sublink is identical with the VRRP message priority in described the 2nd VRRP sublink.
As shown in Figure 5, SR3 supports the transmission of VRRP message priority, be between SR3 and SR1, SR2, to configure respectively a VRRP sublink (VRRP2-1) and the 2nd VRRP sublink (VRRP2-2), VRRP2-1 and VRRP2-2 configuration VRRP message priority transmit, the VRRP message priority that VRRP2-1 sends equals the priority of the VRRP message that VRRP2-2 receives, the VRRP message priority that VRRP2-2 sends equals the priority of the VRRP message that VRRP2-1 receives, thereby indirectly realizes the VRRP2 link of functional area.In this kind of situation, in VRRP2 link, the ID of the VRRP message that SR1 and SR2 send can be not identical.
In above-mentioned two kinds of implementations, SR3 is the message transmitting on transparent transmission VRRP2 link, that is: SR3 does not make any modification to the VRRP message receiving, and directly forwards.And in this kind of implementation, suppose that SR3 receives the VRRP message that SR1 sends, SR3 need to construct new VRRP message and be sent to SR2.And in the VRRP message re-constructing out at SR3, it is consistent that the heartbeat message carrying and SR3 receive heartbeat message entrained in the message that SR1 sends.
Under this kind of implementation, SR3 often receives a VRRP message in SR1 direction, just preserves current message priority, and to SR2 direction, sends the VRRP message of a same priority; SR3 often receives a VRRP message in SR2 direction, just preserves current priority, and to SR1 direction, sends the VRRP message of a same priority.
During concrete enforcement, suppose that SR1 is as main equipment, by SR3, to stand-by equipment SR2, send VRRP message, when SR3 perceives SR3 to the VRRP2-1 link occurs fault between SR1, SR3 will can not receive the VRRP message of SR1 transmission on VRRP2-1 link.On VRRP2-2 link, SR2 can not receive the VRRP message that SR3 sends within a certain period of time, and the overtime master status that becomes.The overtime time that becomes master status of SR2 may be long, and concrete time-out time is relevant with the transmission frequency of VRRP message.In this section of time-out time, the business on VRRP2-2 link may be affected, and for avoiding this impact, should reduce time-out time.Therefore, can by VRRP2-2 link, to SR2, send fast the VRRP message of a minimum heartbeat priority by SR3, thereby trigger SR2, in VRRP2-2 link, become fast master status.The VRRP2-1 of SR3 and VRRP2-2 state can not be simultaneously for standby or be main simultaneously, this situation is error situation, can affect the transmission of business datum in link, need to report corresponding alarm.
Below by form, description taken in conjunction VRRP1 and VRRP2 link, SR1 and SR2 carry out several situations of master/slave switchover.
The principle that table 1SR1 and SR2 carry out master/slave switchover
In the first situation of table 1, in the first link VRRP1, break down, in the first link VRRP1, occur that SR1 and SR2 are the situation of main equipment simultaneously, activestandby state in conjunction with SR1 and SR2 in the second link VRRP2, due in the second link VRRP2, SR1 is also master status, therefore, SR1 finally should be rendered as master status, and SR2 need to be switched to stand-by equipment state by the state in VRRP1 link.
In the second case of table 1, in the second link VRRP1, break down, in the second link VRRP1, occur that SR1 and SR2 are the situation of main equipment simultaneously, activestandby state in conjunction with SR1 and SR2 in the first link VRRP2, due in the first link VRRP2, SR1 is also master status, therefore, SR1 finally should be rendered as master status, and SR2 need to be switched to stand-by equipment state by the state in VRRP2 link.
In the third situation of table 1, SR1 is master status in the first link VRRP1 and the second link VRRP1, and SR2 is stand-by equipment state in the first link VRRP1 and the second link VRRP1, and this state is normal condition, without carrying out state switching.
