Every member device in IRF all can be described as member device, and member device can be divided into two kinds of angles according to function difference
Color, respectively main equipment and slave device.Main equipment is responsible for entire IRF.Slave device can be transported as the alternate device of main equipment
Row.When master-failure, IRF systems can take over former main equipment work from one new main equipment of election from the device automatically.
Usually equal cost multipath load balancing can be formed in the master and slave equipment of IRF.In the IRF, main equipment can be based on
The advertising of route that neighbor device is sent, study routing, and forwarding table is generated, and the forwarding table is issued based on the routing learnt
To slave device.
However, in slave device escalation process, slave device can delete forwarding-table item all in this equipment.And from
During device upgrade, and since slave device is upgrading, main equipment will not learn to the corresponding routing of slave device interface and
Outgoing interface on main equipment will be deleted for the forwarding-table item and route table items of the slave device interface.
From when slave device upgrades completion, slave device needs to wait for setting duration.
In setting duration from when the slave device upgrades completion, the interface that main equipment can newly learn the slave device is corresponding
Routing, and generate the forwarding-table item of the corresponding routing of slave device interface (outgoing interface of the forwarding-table item is connect for the slave device
Mouthful).Main equipment including the forwarding-table item that outgoing interface is the slave device interface, can issue all forwarding-table items of local record
To slave device so that slave device can utilize the outgoing interface message to be instructed to forward for the forwarding-table item of the slave device interface.
After setting duration from when slave device upgrades completion, main equipment and slave device complete master and slave role switching.It is cutting
After changing, the main equipment that former slave device becomes in current IRF participates in message forwarding, and former main equipment becomes the slave device in current IRF
Afterwards, upgrading is performed.
However, the setting duration is usually by manually being set, when the setting duration set it is too short so that main equipment is also not
Learn to whole corresponding routings of slave device interface, main equipment is not the slave device interface the outgoing interface of the whole
Forwarding-table item is handed down to slave device, causes to only exist the forwarding-table item of part path in slave device.When master-slave equipment performed master,
After role switching, for message to be instructed to forward, former main equipment is used to upgrade former slave device.And at this point, only being deposited in former slave device
In the forwarding-table item of part path, cause partial discharge path obstructed, cause to stop.And when setting duration setting is long,
Entire update time can be caused elongated again.
For example, as shown in Figure 1, Fig. 1 is the exemplary plot of IRF shown in one exemplary embodiment of the application a kind of；
Assuming that the three-tier switch 1 and 2 in Fig. 1 is formed into an IRF virtual unit.Three-tier switch 1 be main equipment, three
Layer switch 2 is slave device.Equal cost multipath load balancing can be formed on three-tier switch 1 and three-tier switch 2.With downlink
For flow, path 1 as shown in Figure 1 and path 2 can be formed.
During three-tier switch 2 upgrades, three-level interchanger 1 instructs message to forward (message passage path 1 is forwarded),
The forwarding-table item and route table items of the interface on 2 grade three-tier switch 2 of interface 4 and interface recorded on three-tier switch 1 can
It is deleted, and since three-tier switch 2 is upgrading, three-tier switch 1 learns less than 2 grade three-tier switch 2 of interface 4 and interface
On the corresponding routing of interface.
From when three-tier switch 2 upgrades completion, three-tier switch 2 needs to wait for setting duration.In the three-tier switch 2
In setting duration from when upgrading is completed, since three-tier switch 2 is completed to upgrade, so three-tier switch 1 may be learned out and connect
Routing of the mouth for the interface on 2 grade three-tier switch 2 of interface 4 and interface, and generate on 2 grade three-tier switch 2 of interface 4 and interface
Interface forwarding-table item.All forwarding-table items of local record can be 4 He of interface including outgoing interface by three-tier switch 1
The forwarding-table item of interface on 2 grade three-tier switch 2 of interface, is handed down to three-tier switch 2, so that three-tier switch 2 can
Message is instructed to forward using the forwarding-table item that this is issued.
After setting duration from when the three-tier switch 2 upgrades completion, three-tier switch 1 is switched to slave device and performs
Upgrading, three-tier switch 2 are switched to main equipment.
However, the setting duration is usually by manually being set, when the setting duration set it is too short so that three-tier switch
1 does not learn also to whole corresponding new routings of 2 interface of three-tier switch (such as 2 interface of interface 4 and interface), three layers of friendship
It changes planes and 1 the forwarding-table item of interface of the outgoing interface of the whole for the three-tier switch 2 is not handed down to slave device, cause three layers
The forwarding-table item of part path is only existed on interchanger 2.When three-tier switch 1 is switched to slave device, three-tier switch 2 is switched to
After main equipment, for message to be instructed to forward, three-tier switch 1 is used to upgrade three-tier switch 2.And at this point, three-tier switch 2
There are the forwarding-table items of part path, cause partial discharge path obstructed, cause to stop.And when the preset time period is long,
Entire update time can be caused elongated again.
In view of this, in this application, main equipment can determine that associated first forwarding-table item of slave device to be upgraded.
After the completion of slave device upgrading, main equipment can be synchronized to locally recording comprising all forwarding-table items including the first forwarding-table item
Slave device.After synchronously completing, master and slave equipment can perform master and slave role switching.After handover, former main equipment performs upgrading, former
Slave device is based on above-mentioned first forwarding-table item and carries out message forwarding.
On the one hand, since former slave device is after main equipment is switched to, it is the slave device interface to have whole outgoing interfaces
The first forwarding-table item so that all flows for flowing through the original slave device can be forwarded, so as to reduce cutout.It is another
Aspect is significantly shorter than above-mentioned setting duration since all forwarding-table items are synchronized to the former slave device required time by former main equipment
(former main equipment study routing, and according to routing generation forwarding-table item learn, by forwarding-table item be handed down to slave device when
It is long), therefore the update time of equipment in IRF can be greatly shortened.
