Description
Technical field
The present invention relates to the communications field, in particular to a kind of neighbor state processing method based on ISIS agreement and
Device.
Background technique
In the related technology, Intermediate System to Intermediate System (ISIS) is that one kind is dynamic, is based on link state
Interior Gateway Protocol (IGP).ISIS agreement is negotiated after establishing neighbours by hello packet interaction, each intermediate system
(IS, Intermediate System) all generates the link that link-state protocol data packet (LSP) describes this intermediate system (IS)
Status information, and be sent in network, and can also store all intermediate system (IS) equipment in network topology and send over
LSP is formed link state database (Link State Data Base, LSDB).ISIS is exactly to use link state database
The Optimization route up to destination address is calculated by shortest-path first algorithm (SPF).
Graceful Restart (GR) is the state that can be restored to before restarting after ISIS is restarted, and succession is all before restarting
The method that information continues to run.Other routers on network are allowed to continue to retain original within this of short duration time that IS-IS is restarted
There is link state；Restarter keeps the forwarding information before restarting, i.e. FIB (Forwarding in a short time
Information Base) it can keep in short term stablizing on restarter, thus not traffic impacting forwarding；Router
After restarting, it is synchronous that LSP data library is completed with neighbor router rapidly；SPF operation is carried out again after LSP data library synchronously completes.
For the relevant technologies in RFC6213 version, the foundation of neighbours introduces two-way converting detection (Bidirectional
Forwarding Detection, BFD), when ISIS agreement an interface configure BFD after, once BFD cannot establish or in
Disconnected, neighbours will be in the state of down.But during Graceful Restart (GR), after ISIS agreement is got up, it is received other
The hello packet of neighbours (helper), creation neighbours simultaneously notify creation BFD, at this time BFD also in down state, then will
Meeting active transmission hello packet, describing setting neighbours according to agreement RFC6213 is down, causes to be directed to this on other neighbours
The direct down of the neighbor state of the equipment of a GR falls, and destroys the prerequisite that GR neighbours cannot interrupt, and leads to GR equipment neighbours
Failure.Cause GR equipment GR that cannot succeed forever.

The present embodiment is alternative embodiment of the invention, for the application to be described in detail:
The present embodiment based on agreement RFC6213 propose the case where BFD state relation neighbours are established, provide one kind
Neighbours' method for building up when ISIS protocol grace rebooting guarantees that Graceful Restart is smooth.The scheme of the present embodiment includes:
One intermediate system (IS) sends hello packet to helper (neighbours) and carries RR (weight in Graceful Restart (GR)
Open request), neighbours' intermediate system (IS) sends hello packet and RA is arranged (request is responded).The intermediate system of Graceful Restart connects
The hello packet for receiving the setting RA of neighbours' intermediate system (IS) transmission, creates neighbours and is directly disposed as neighbor state
UP ignores the neighbor state of current BFD.
In a specific scene, an intermediate system (IS) is in Graceful Restart (GR), on broadcast network interface,
Hello packet is sent, when respective neighbours information is set in hello packet, ignores the BFD state of this neighbour, according to ISIS neighbour
The virtual condition in residence is configured hello packet neighbours TLV (type-length-value).I.e. at neighbours TLV (type-length-value)
In fill in the mac address information of this neighbour of hello packet.
In another specific scene, an intermediate system (IS) is in Graceful Restart (GR), on point-to-point interface,
Hello packet is being sent, when respective neighbours information is set in hello packet, is ignoring the BFD state of this neighbour, according to ISIS
The virtual condition of neighbours is configured in the point-to-point neighbours 3-way TLV (type-length-value) of hello packet.I.e. in point pair
The virtual condition of this neighbour is filled in the neighbours TLV (type-length-value) of point.
In the present embodiment, an intermediate system (IS) ignores any variation of neighbours BFD in Graceful Restart (GR),
That is UP, DOWN has occurred in BFD, manages DOWN, invalid to the influence of neighbor state.
Optionally, intermediate system (IS) is associated with ISIS neighbours and respective neighbours BFD after Graceful Restart (GR) again
State down is fallen into this neighbour if BFD cannot be established as UP；Otherwise, neighbor state keeps UP.
Implement example one:
Such as Fig. 1, the network being made of R1 and R2, what R1 and R2 were configured GR function, what R1 and R2 were established is radio network
Neighborhood.
In the case that the BFD described in enabled RFC6213 and neighbours bind, BFD is not established, then neighbours can not
UP.At this point, switching if R1 carries out GR, R1 is after start-up, it will RR flag bit is sent in hello packet, R2 receives R1
The hello packet for carrying RR can reply RA flag bit later, after R1 receives the hello packet of carrying RA flag bit of R2, immediately
Neighborhood is established with R2, while establishing corresponding neighbours BFD to the management module of BFD notice, and the state of obvious BFD is not at this time
In the presence of then the neighbor state of this neighbour of R2 will stay in that INIT on R1.Hello packet is sent to R2, hello packet simultaneously
In be in INIT but BFD state is not present due to neighbours, the MAC Address of R2 will not be carried in hello packet.R2 is received
After such a hello packet of R1, it is found that the MAC Address of itself is not present in the hello packet of R1, it will this R1 neighbour
It occupies DOWN to fall, thoroughly leads to the failure of R1GR.
According to the scheme of the present embodiment: being switched if R1 carries out GR, R1 is after start-up, it will sends out in hello packet
RR flag bit is sent, the hello packet that R2 receives R1 carrying RR can reply RA flag bit later, and R1 receives the carrying RA flag bit of R2
Hello packet after, establish neighborhood with R2 immediately, while establishing corresponding neighbours BFD to the management module of BFD notice,
The state of obvious BFD is not present at this time, however since R1 is in GR state, it will the institute for ignoring BFD is stateful, then neighbours are just
It often establishes, neighbor state UP.R1 then sends hello packet, since R1 is in GR state, will not pay close attention to the BFD of neighbours
State, the hello packet of transmission normally carry the MAC Address of R2.So, R2 has received the hello that R1 carries oneself MAC Address
Message, neighbours are in UP state.So, any interaction of subsequent GR all executes on this stable neighbor, and the GR of R1 is able to smoothly
It carries out.R1 binds BFD and neighborhood after GR, if BFD is still unable to UP, DOWN is fallen on R1
This neighbour of R2；Otherwise, neighbours keep UP state.
Implement example two:
Such as Fig. 1, the network being made of R1 and R2, what R1 and R2 were configured GR function, what R1 and R2 were established is point-to-point
Neighborhood.
In the case that the BFD described in enabled RFC6213 and neighbours bind, BFD is not established, then neighbours can not
UP.At this point, switching if R1 carries out GR, R1 is after start-up, it will RR flag bit is sent in hello packet, R2 receives R1
The hello packet for carrying RR can reply RA flag bit later, after R1 receives the hello packet of carrying RA flag bit of R2, immediately
Neighborhood is established with R2, while establishing corresponding neighbours BFD to the management module of BFD notice, and the state of obvious BFD is not at this time
In the presence of then the neighbor state of this neighbour of R2 will stay in that INIT on R1.Hello packet is sent to R2, hello packet simultaneously
In be in INIT but BFD state is not present due to neighbours, it will the neighborhood that R2 is arranged in hello packet is DOWN.
After R2 receives such a hello packet of R1, the neighborhood where finding itself in the hello packet of R1 is DOWN, it will
This R1 neighbours DOWN is fallen, the failure of R1GR is thoroughly caused.
According to the scheme of the present embodiment: being switched if R1 carries out GR, R1 is after start-up, it will sends out in hello packet
RR flag bit is sent, the hello packet that R2 receives R1 carrying RR can reply RA flag bit later, and R1 receives the carrying RA flag bit of R2
Hello packet after, establish neighborhood with R2 immediately, while establishing corresponding neighbours BFD to the management module of BFD notice,
The state of obvious BFD is not present at this time, however since R1 is in GR state, it will the institute for ignoring BFD is stateful, then neighbours are just
It often establishes, neighbor state UP.Meanwhile the hello packet that R1 is then sent will not pay close attention to neighbour since R1 is in GR state
The BFD state in residence, the neighbor state of the hello packet setting UP of transmission.So, R2 has received R1 and carries oneself as UP neighbours' shape
State, then R2 also keeps this neighbour of R1 to be in UP state.So, any interaction of subsequent GR is all held on this stable neighbor
Row, the GR of R1 are smooth.R1 binds BFD and neighborhood after GR, if BFD is still unable to UP,
DOWN is so fallen into this neighbour of R2 on R1；Otherwise, neighbours keep UP state.
Through this embodiment, the success rate of ISIS GR is improved, because when ISIS starts GR, the success of neighbours
Foundation is the crucial first step, if cannot establish will thoroughly lead to the failure of GR.
