In the previous article, we described how to use Quagga to turn the CentOS server into a BGP router, as well as the BGP peer and prefix Exchange settings. In this tutorial, we will focus on how to use prefix list prefix-list and route map Route-map to control data injection and data output separately.As previous articles have said, BGP routing decisions are based

Rd and RT (mpls vpn bgp) Rd (route-distinguisher) is used to identify different VPN instances on the PE device. Its main function is to achieve address multiplexing between VPN instances. It and the IP address constitute a 12byte vpnv4 address space, rd and the route are carried together in the bgp update message and published to the peer end. On the one hand, we need to verify whether the RD function is im

Border Gateway Protocol (BGP) is mainly used for interconnection between autonomous systems (AS) on the Internet. The main function of BGP is to control route propagation and select the best route. BGP is an enhanced, comprehensive, and scalable protocol developed by the Internet Engineering Task Group. A bgp data cent

To get a thorough understanding of BGP, we'll start by answering the seemingly simple question of why BGP is needed, that is, how BGP is generated, and what it solves. With these questions, we will briefly review the trajectory of a routing protocol development.The essence of the first route is to describe the expression of a network structure, and the routing ta

The Prepend () method inserts the specified element into the matching element at the beginning of the internal, and the function is essentially the same as the Prependto () method, which differs only in grammatical terms, although it is essentially the same in terms of grammatical form. The following syntax structure is described below: Copy Code code as follows: $ (selector). prepend (con

1. Several issues restricting BGP scalability BGP is an IP network protocol currently used on the Internet. It provides stable and secure routing protocols for intercommunication between operators and provides a wide range of routing control mechanisms. To better control routing policies, most carriers deploy BGP to backbone routers. As the network expands, the

I. background A route consists of two basic actions: determining the optimal path and transmitting information groups through the network. The Network Transmission Group is relatively simple, and the determination of the path can be complicated. BGP is a protocol for Path Selection in today's networks. This document briefly describes the basic operations of BGP and describes its Protocol components.

7. A set of required routing policies 　　 BGP policies are implemented in the form of configuration information. This information is not directly incorporated into the Protocol. Therefore, BGP can provide very complex routing policies. However, all BGP implementations are not required to support these policies. We do not try to standardize routing policies so that

1. Introduction BGP is a routing protocol between autonomous systems. The Network accessibility information exchanged by BGP provides sufficient information to detect the routing circuit and determine the route based on the performance priority and policy constraints. For details, see RFC 1104 [2]. In particular, BGP exchanges the network accessibility informatio

1. Append () and prepend () Suppose Use $ ('. a '). Append ($ ('. C ')); The effect is as follows: Same use $ ('. a '). Prepend ($ ('. C ')); The effect is as follows: 2. Use after () and before () Use the same assumption code: $ ('. a '). After ($ ('. C ')); The effect is as follows: Same use before () $ ('. a '). Before ($ ('.

As the customer's network scale and coverage grow, the use of BGP routing protocols is no longer the privilege of the operator's network, and more enterprise networks are also deploying BGP. BGP can support a larger network, a wide range of routing policies, and a large number of route table capacity. However, the BGP

One, the DOM API is also constantly upgradingWeb front-end standards have been constantly upgraded, for example, for many years HTML5, CSS3, and every day to see ES6.Then, there seems to be no then. In fact, in addition to the html5/css3/es6+, the DOM standards are constantly escalating, and browsers are quietly following up and supporting them.However, this follow-up and support is very low-key and conceal, plus the industry's voice is mostly focused on the JS engineer, while the DOM this thing

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 Routing Protocol, also known as EGP autonomous system, the same internal gateway protocol and unified measurement value are used to forward data packets within the AS, and an external gateway protocol is used to forward data
