What are the BGP types in the vrobgp, the BGP types are common problems, how to understand the BGP types, and what related passwords are there, all of them will be fully resolved in this article. What is an autonomous system? An autonomous system is a vro and network group under the control of a management organization. It can be a vro that is directly connected

Quagga is an open source routing software suite. In this tutorial, I will focus on how to turn a Linux system into a BGP router or use Quagga to demonstrate how to establish BGP peer-to-peer w

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 traffic of 192.168.1.0/24 is allowed. WKiom1T5Lv

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 (Edge Gateway Protocol) protocol, while OSPF and protocol. BGP was developed on the basis o

In the IGP era, we all know, for example, OSPF, link state protocol, in the routing of the time, than the cost of the link, which link consumption will be more priority, if two of the same link consumption, then do load balancing. In fact, the 2 principles to achieve the OSPF---shortest path first work principle. What if, in BGP, there are multiple routes to achieve the goal, how should the choice be made? Which path is the preferred one? Take a lo

BGP Configuration Requirements:No synchronizationNo auto-summary IBGP uses LOOPBACK to establish a neighbor, and the next hop points to itself3. RT1 and RT2 publish a summary route of AS65000 to BGP: 10.0.0.0/16 and 10.3.0.0/16.4. RT5 publishes a summary route fo

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. 1. Introduction BGP is a routing protocol between autonomous systems. The network accessibili

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 structure. 1. Introduction BGP is a routing protocol between autonomous systems. The network accessibility information exchanged by
