Described detection components 40' includes:
Memory element 401', for saving as the advertising of route association testing conditions of routing configuration.Described road
By noticing listed by embodiment two seen from association testing conditions.
Detection example 403', for detecting the state of detection object.Described detection example can be wrapped
Include the one or many in routing diagram, neighbor picture, two-way converting detection BFD and operation management maintainance OAM
Kind.
Judging unit 405', for closing joint inspection from the advertising of route having noticed route described in memory element acquisition
Survey condition, relatively described advertising of route association testing conditions detect state and described detection expected from object
The state of the described detection object that example detection arrives, as state is different, it is determined that described advertising of route associates
Testing conditions is unmet and notifies described Routing Protocol assembly.As state is identical, do not process.
Judging unit can be when knowing that by detection example the state of detection object changes, from memory element
Notice the advertising of route association testing conditions of route described in acquisition, and carry out described comparison.
The route withdraw scheme of the present embodiment, equally supports the route withdraw of the most flexible more scene.
Such as, after neighborhood between routing device and neighbours routing device A or session disconnect, Ke Yitong
Know that neighbours routing device B quickly cancels this routing device and is communicated to the default route of neighbours routing device B,
Accelerate the speed of routing convergence.As carried out the configuration of route withdraw association testing conditions, Ke Yi by the network segment
When neighborhood or session disconnect, quickly cancel the route of a certain network segment.
Below by several examples, such scheme is illustrated.
Example one
This example notices route based on the association testing conditions become more meticulous, according to application scenarios, configuration route
Noticing association testing conditions, advertising of route association testing conditions includes detecting object and intended state thereof,
As including but not limited to:
One or more peer-to-peers of this routing device and setting set up neighborhood；
One or more route set exists；
Set one or more route up to；
(state as " UP ") is set up in one or more sessions (such as BFD session, OAM session etc.) of setting.
Between above-mentioned testing conditions can be the relation of logical AND can also be logic or relation.As long as
The condition affecting advertising of route is all configurable in advertising of route association testing conditions.
When routing device notices route, as shown in Figure 6, following process is performed:
Step 410, obtaining the advertising of route association testing conditions waiting to notice route, if got, holding
Row step 420, if do not got, performs step 450；
Do not get advertising of route association testing conditions, it may be possible to be configured without, although or have configuration,
But configuration information is the most complete or against regulation.
Step 420: detected in described advertising of route association testing conditions by detection example and detect object
State, if be detected that, performing step 430, if be not detected by, performing step 450；
It is not detected by detecting the state of object by detection example, it may be possible to detection example does not exists, or
Although detection example exists, but do not comprise corresponding detection object or be not detected by described detection object
State.Such as, user is configured with route A in advertising of route association testing conditions, but does not also have
The particular content of configuration route A is even without creating route A, and detection example will detect detection object
Do not exist.Routing diagram, neighbor picture, BFD and OAM all can be as detection example (routes herein
Figure, neighbor picture contain to route, detection that neighbours are relevant, maintenance function).
Step 430: compare and detect state expected from object in advertising of route association testing conditions and detect real
The state of the described detection object that example detects, if identical, then advertising of route association testing conditions obtains
Meet, perform step 440, if it is different, perform step 460；
Step 440, waits to notice route to described in neighboring peers notice, terminates；
If advertising of route association testing conditions is the routing configuration for a network segment, only meeting
During this advertising of route association testing conditions, just can notice the route specifying the network segment to neighboring peers.
Step 450, by described wait to notice route be considered as being not provided with advertising of route association testing conditions wait lead to
Accuse route, carry out advertising of route process, terminate；
Herein, for do not configure advertising of route association testing conditions, or as aforementioned a variety of causes fail right
When advertising of route association testing conditions effectively detects, still according to not configuring advertising of route association detector bar
Common mode during part, carries out advertising of route to described route to be noticed.
Step 460, do not notice described in wait notice route.
If the advertising of route association testing conditions for routing configuration to be noticed, and can to this route
Notice association testing conditions effectively to detect, if now this advertising of route association testing conditions can not obtain
To meet, the most do not notice described in wait notice route.
This example can associate testing conditions more flexibly when neighboring peers notices route, such as,
If when there is route B and there is the scene just noticing route A, just lead in the route for route A configuration
Accuse association testing conditions in, can will route B as detection object, it is contemplated that state be configured to " route
Exist ", thus realize this scene, and this cannot realize under traditional approach.
Example two
This example relates to the method cancelling route, to noticing route, closes at the advertising of route configured for it
When connection testing conditions can not be met, it is cancelled.
This example routing device cancel route method as it is shown in fig. 7, comprises:
Step 510, knows that the state of detection object changes；
Detection example can be polled by routing device, to know whether that the state detecting object occurs
Change, specifically can be performed corresponding flow process by the processor in routing device and realize.Detection example also may be used
During to change in state detection object being detected, proactive notification routing device.These detection examples
The Fast Detection Technique such as BFD, OAM can be used.
Step 520, obtains the advertising of route association testing conditions having noticed route；
Some are noticed to route, the advertising of route association testing conditions of effect may be not configured with.These
Notice route and can carry out route withdraw process according to existing agreement regulation.
Step 530, determine described in noticed route advertising of route association testing conditions whether be met,
As not being met, performing step 540, if be met, not processing, terminate；
Step 540, noticed described in notice the neighboring peers that route is communicated to cancel described in notice
Route, terminates.
According to above-mentioned flow process, after finding that testing conditions is unsatisfactory for, route can be sent to neighboring peers
Revocation message, neighboring peers can quickly cancel route as quickly cancelled the route specifying the network segment, so
Routing convergence speed can be improved, reach the ability of Millisecond routing convergence.
