To make the object, technical solution and advantage of the application be more clearly understood, referring to the drawings to application scheme It is described in further detail.
The embodiment of the present application is described as the process of ospf process distribution Router Distinguisher, but this Shen by taking ospf protocol as an example Routing protocol type is not limited please.
Fig. 1 show a kind of schematic network structure.Two ospf process are separately operable in router 1 and router 2. Each ospf process identifies link-state information promoter's when carrying out link-state information exchange, by Router Distinguisher Identity, therefore, in consolidated network, the Router Distinguisher of each ospf process cannot repeat.
In prior art, by manual configuration, ensure to distribute unique Router Distinguisher for each ospf process. Such as:The Router Distinguisher of process 1 is 1.1.1.1 in router 1;The Router Distinguisher of process 2 is 2.2.2.2 in router 1; The Router Distinguisher of process 1 is 3.3.3.3 in router 2;The Router Distinguisher of process 2 is 4.4.4.4 in router 2.But When, there are when a large amount of ospf process, the workload of manual configuration increases, and time-consuming, and is easy error in network.
In view of the above-mentioned problems, the embodiment of the present application proposes a kind of method of distribution Router Distinguisher, from connecing for routing device An interface is selected in mouthful, and distributes to corresponding routing daemon using the IP address of the interface as Router Distinguisher.
Referring to Fig. 2, one embodiment flow chart of Router Distinguisher method is distributed for the application, the embodiment is to distributing road The process identified by device is described.
Step 210, select an interface as target interface from the interface of routing device.
When being configured to routing device, multiple ospf process can be configured in a routing device, and will routing Corresponding ospf process is added in the interface of equipment according to actual needs.Before distributing Router Distinguisher to ospf process, routing is set Standby interface can be taken by DHCP (Dynamic Host Configuration Protocol, dynamic host configuration protocol) Business device obtains IP address automatically, and the IP address the whole network is unique.
When distributing Router Distinguisher to ospf process, first determine whether the ospf process has been configured with router mark Know, the mode that manual configuration usually may be used is that ospf process configures Router Distinguisher.If had by hand in ospf process The Router Distinguisher of configuration then preferentially selects the Router Distinguisher of manual configuration.
If the not no Router Distinguisher of manual configuration in ospf process, further judges whether ospf process is provided with Whether Router Distinguisher associated interface is provided with being associated with for Router Distinguisher and a certain interface of routing device that is, in ospf process Relationship, the Router Distinguisher associated interface can be the interfaces in this ospf process, can also be connecing in non-ospf process Mouthful.According to judging result, a point following two situations are handled:
When ospf process be provided with Router Distinguisher associated interface when, select specified Router Distinguisher associated interface as Target interface.Such as:There are interface 1 and interface 2 in the process 1 of router 1, then can be the router mark of process 1 with specified interface 1 Know associated interface, can also specified interface 2 be process 1 Router Distinguisher associated interface.It should be noted that each OSPF The Router Distinguisher associated interface being arranged in process cannot be identical, to prevent different processes from getting identical router mark Know.
When Router Distinguisher associated interface is not arranged for ospf process, work(can be automatically selected by the way that Router Distinguisher is arranged Can, select the interface of first operation in ospf process as target interface.Such as:There is 3 He of interface in the process 2 of router 1 Interface 4, when process 2 is not provided with Router Distinguisher associated interface, then process 2 can automatically select an interface as target Interface, the interface that the principle selected runs for first in process 2, it is assumed that interface 3 is the interface of first operation, then interface 3 The target interface selected for process 2.
Step 220, the Internet protocol IP address of target interface is distributed into routing daemon as Router Distinguisher.
After selected target interface, corresponding road can be distributed to using the IP address of the target interface as Router Distinguisher By process.The IP address of the interface of known routing device is obtained by DHCP from abovementioned steps 210, which protects The uniqueness of interface IP address has been demonstrate,proved, therefore, has been distributed the IP address of some interface in routing device as Router Distinguisher To corresponding routing daemon, it is ensured that Router Distinguisher the whole network of each process is unique.
Since the interface IP address of routing device uses DHCP acquisition modes, after routing device power down or failure are restarted, Again to Dynamic Host Configuration Protocol server IP address requesting, therefore, the IP address of interface may change.As the IP of selected target interface When address changes, the Router Distinguisher of the IP address update routing daemon of the target interface after variation can be used.
The process of above-mentioned distribution Router Distinguisher is allocated according to the interface message of routing device, if in routing daemon The function that Router Distinguisher is configured according to interface is not set, then can be whether to be configured with global router mark in query routing equipment Know, which is before system operation for the unique mark of each routing device distribution.
When being configured with global Router Distinguisher in routing device, for there are the routing device of multiple ospf process, The Router Distinguisher of each ospf process is the overall situation Router Distinguisher.Although as it can be seen that can according to global Router Distinguisher Route Distinguisher is distributed to routing daemon in routing device to realize, but can not ensure the uniqueness of Route Distinguisher.
When global Router Distinguisher is not configured in routing device, select IP address in routing device total interface maximum Router Distinguisher of the IP address as ospf process, it is preferential to select in loopback interface the maximum IP address of IP address as router Mark.When the method for salary distribution there are the routing device of multiple ospf process for coming, the feelings that Router Distinguisher repeats are equally existed Condition.
