BGPBorderGatewayProtocol) is the Border Gateway Protocol used to connect to independent systems on the Internet. It is an enhanced, comprehensive, and scalable protocol developed by the Internet Engineering Task Group. BGP4 supports the CIDR addressing scheme, which increases the number of available IP addresses on the Internet. BGP was designed to replace the or

With the development of the Internet in China, the connection between ISP service providers and Internet is also changing. On a network connection, from a single connection to the Internet via multiple telecommunications companies, in terms of routing protocols used, from the use of static routing protocols to the use of BGP (Border Gateway

10. Conclusion The BGP protocol provides high control and flexibility for Inter-Domain Routing, implements policy constraints, and avoids routing loops. The guidelines described here provide a starting point for BGP use. As BGP gr

The command is executed on R1: Router bgp 100 Network 99.99.99.0 mask 255.255.255.0 backdoor During backdoor routing, note that if you advertise that a master-class network can be configured without a mask, the configuration must be the same as that of th

Design of the BGP Practice Policy Routing distribution requirements for the two RoutersR1 and R2 are connected by two lines. BGP is used. R1 has two groups of routes, 192.168.1.0/24 and 192.168.2.0/24. When both lines are connected, the traffic of the two groups of routes is distributed and balanced on the two lines. When any one of them is disconnected, only tra

1. BGP Route synchronization Concept BGP protocol: A router running the BGP protocol will not advertise the routing information learned from the internal peer (IBGP neighbor) to the external peer (EBGP neighbor ), unless the rout

In network protocols, the use of BGP is complex to many extent. This is caused by different IP addresses of different hosts, different network connections, different terminals and hardware interfaces. Therefore, there are many types of routing protocols in our network protocols. BGP is an external gateway protocol desi

External Gateway Protocol: BGP (Border Gateway Protocol) BGP: the protocol for exchanging route information between as routers of different self-made systems. The Internal Gateway Protocol rip or OSPF is used to send a datagram to

BGP is a familiar protocol. Then, let's give a brief explanation of this Protocol. It mainly targets its synchronization performance. You need to pay attention to this aspect. BGP protocol: A router running the BGP

the routing protocol. The names are the Open Shortest Path First and the Border Gateway Protocol. Earlier than them, the RIP and r1_2 protocols are called distance vector protocols. These three protocols have become the most widely used dynamic routing protocol with the com

At present, there are also a lot of BGP routing protocol applications, so I have studied the synchronization problem in the BGP routing protocol. Here I will share it with you and hope it will be useful to you.
