Open the route aggregation networking schematic diagram of embodiment.As shown in Fig. 2, RTA, RTB and RTC are routing device.It is built between RTA and RTB
Vertical OSFP (OSPF is only an example, can also be other IGP) neighbours, RTB learn to OSPF to route by ospf protocol, example
Such as 2.2.2.0/24 routing.Bgp neighbor is established between RTB and RTC, and BGP is configured on RTB, RTB introduces OSPF in BGP,
It generates and issues polyaluminium chloride PAC 2.2.0.0/16 to RTC, RTC is received and can be instructed flow after the hair forwarding table on lower brush polymerization road
Forwarding.
Assuming that there are 20000 OSPF to route on RTB, after RTB is restarted, forwarding table that RTB respectively routes each OSPF
Under brush hardware (such as successively by the forwarding table of 2.2.2.0/24 routing, 2.2.2.0/24 routing and the routings such as 2.2.2.0/24
Under brush hardware).
In the related technology, the BGP on RTB just generates polyaluminium chloride PAC when introducing first OSPF routing, and is sent to
RTC makes corresponding discharge on RTC switch to RTB.Since the speed of brush to hardware under the forwarding table of OSPF routing on RTB is slower, this
When 20000 OSPF routing forwarding table brush successfully there is no completely lower, corresponding discharge on RTC is switched to RTC at this time may
Lead to traffic loss.
The method shown in FIG. 1 for generating polyaluminium chloride PAC can be applied to the routing device for being configured with BGP, such as shown in Fig. 2

Any one Routing Protocol, such as OSPF, ISIS or RIP etc., with no restrictions to this disclosure.The road of specified Routing Protocol
By specified circuit can be indicated by the routing of protocol discovery.The routing of specified Routing Protocol can be divided into first publication routing and routine
Publication routing.
Wherein, the routing issued for the first time in routing of the first publication routing for specified Routing Protocol, i.e. routing device are for the first time
The routing learnt, the forwarding table of the routing not yet brush down the hardware (such as: forwarding chip, conversion board etc.) of routing device.
The routing that routine publication routing had learnt for routing device in the routing of specified Routing Protocol, the forwarding table of the routing is
Under brush the hardware of routing device.
In one possible implementation, routing device can will be introduced into the routing of specified Routing Protocol of BGP,
The routing that forwarding table does not brush down hardware is determined as issuing routing for the first time.
In one possible implementation, routing device can be brushed under the forwarding table for determining routing to hardware,

2.2.2.0/24 have in the routing of equal OSPF 4000 be first publication routing, 1000 be customary routing, wherein first publication
The forwarding table of routing not yet brushes down hardware, and the forwarding table of routine routing brushes hardware down.On this 4000 first publication roads
By forwarding table brush hardware down when, RTB can based on the routing for the OSPF being introduced into generate polyaluminium chloride PAC 2.2.0.0/
16, polyaluminium chloride PAC is issued to RTC.According to the forwarding table of polyaluminium chloride PAC 2.2.0.0/16, destination address can be by RTC
2.2.2.0/24 the flow waited switches to RTB.It brushes since on RTB, the forwarding table of the routings such as 2.2.2.0/24 has been descended to hardware,
Therefore it is the flow of 2.2.2.0/24 etc. that RTB, which can normally forward destination address, to reduce traffic loss.
