1 Some problems of restricting BGP expansibility
BGP is the IP network Interconnection protocol applied to Internet, which provides a stable and secure routing protocol for the interconnection between operators, and has rich routing
The basic Border Gateway Protocol (BGP) routing selection protocol is divided into two types: l Internal Gateway Protocol (IGP) l external Gateway Protocol (EGP) BGP is an Inter-Domain
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
200, which is the same as the AD value of the IBGP route, and the AD value is greater than any IGP protocol.
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
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
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
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
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.
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
BGP protocol overview * BGP autonomous system-AS is a group of centrally managed routers that use the same internal gateway protocol and unified measurement values in AS internal routing groups, and use the external gateway protocol
If you have more than one Internet connection, you know that simply using the Boundary Gateway Protocol (Border Gateway PROTOCOL,BGP) makes it difficult to get the optimal routing path. At this point, the 7th signaling system without a telecommunications network is subtle (signaling system 7,SS7). As the control surfac
The BGP protocol is one of the routing protocols. Therefore, we use it for many purposes. The most important reason is that we use the BGP protocol to mitigate the depletion of IP address barrier space. Why can it do this? Next we will introduce this agreement in detail.

BGP is a dynamic routing Discovery protocol between autonomous systems, and its basic function is to automatically exchange loop-free routing information between autonomous systems. As with OSPF and RIP protocols that operate within autonomous zones, BGP is a class of EGP (E
The BGP protocol in the routing protocol is a type of protocol we will analyze for you below. As this part of the content is very important, we will mainly introduce it in two parts: first, the introduction of the concept above, and then a brief analysis of its topology stru
