Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing alsoFor embodiment, technical scheme of the present invention is elaborated.
A kind of route issuing method is provided in the embodiment of the present application, in the time issuing route, accesses according to routing deviceThe state of network is determined cost (cost) value of issuing this route, so that receive the routing device root of this routeCalculate rational path according to this cost value, thereby can ensure the normal transmission of flow.
Below in conjunction with accompanying drawing, describe route issuing process in the embodiment of the present application in detail.
Referring to Fig. 1, Fig. 1 is that in the embodiment of the present application, route is issued schematic flow sheet. Concrete steps are:
Step 101, routing device is distributed to the route of other routing device for need, configuration routing policy, instituteStating routing policy comprises: matching condition is the first state, moves as the acquiescence cost value of this route is increased pre-If value.
This preset value is to be greater than 0 integer; In the time of specific implementation, will give tacit consent to cost value increases after preset value,Be no more than maximum cost value corresponding to route in concrete agreement.
As Intermediate System-to-Intermediate System (IntermediateSystem-to-IntermediateSystem, IS-IS)In agreement, cost maximum is 16777214; When ISIS specify path cost value type be narrow,When narrow-compatible or compatible, maximum is 63; When the path cost value type of specifying isWhen wide or wide-compatible, span is 16777215.
In agreement that Open Shortest Path First (OpenShortestPathFirst, OSPF), cost maximum is16777215。
Step 102, this routing device is in the time issuing this route, if the state that this routing device accesses network is currentBe the first state, determine and mate with described routing policy, carry out described routing policy, by writing from memory of this routeRecognize cost value and increase preset value as the cost value of issuing this route.
This routing device is issuing when this route, and this routing device accesses network if determine state is current is secondState, using the acquiescence cost value of this route as the cost value of issuing this route.
Wherein, the state that routing device accesses network is summarised as the first state and the second state, in concrete applied fieldIn scape, can give the first state and the second state with real state according to practical application. If certain applicationWhen scene comprises more than three kinds state, a kind of state more than three kinds in state is the first state, three kinds withOther states in upper state are referred to as the second state.
In concrete applied environment, the state that routing device accesses network can be the state of routing device, role;Also can be the state (upordown) of port; It can also be the route that whether has named place of destination locationEtc..
While being VRRP equipment as this routing device, the state that this routing device accesses network is VRRP backupState and VRRP major state, wherein, the first state is VRRP Status of Backups, the second state is VRRPMajor state.
As this routing device exists the route of named place of destination location, the state that this route accesses network is firstState; There is not the route of named place of destination location in this routing device, the state that this route accesses network isThe second state.
Here give an example no longer one by one, in the time of specific implementation, described the first state is to wish to arrive the stream of this routeWhile measuring without path, this routing device place, the state that this routing device accesses network; Also can be that this is establishedStandby as Status of Backups, the not forwarding of participation network uplink and downlink flow.
When such scheme is realized, because the cost value of issuing this route becomes greatly, therefore, remote equipment forWhen this route is carried out route calculating, will preferentially calculate on the path that cost value is little, send out and can not be switched toOn the path at the routing device place that this route of cloth cost value is large.
