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

Tunneling technology is a very important application in IPV6 transition technology. Depending on how the IPv4 address of the tunnel endpoint is obtained, the tunnel is divided into "manual tunneling" (or "Configuration Tunnel") and "Automatic Tunneling". Compared with manual tunnels, automatic tunnels are more flexible in configuration and use. While the ISATAP

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

distance is 110. As the Shortest Path protocol, the metric number must be relatively small unless the link is disconnected. How, isn't it more complicated than Cisco's configuration? In fact, it is very easy to use. In addition, OpenBSD uses pf to filter data packets at the network layer, allowing or rejecting data packets from other places, which ensures security. In addition, OpenBSD native supports Vlan, IPSec, Tunnel, carp, and trunk (link aggre

In March 1999, the Internet Task Force (IETF) published a RFC2547 by Cisco, describing a way for operators to provide virtual private network (VPN) services to users through an IP backbone network. This method uses an extended BGP (Boundary routing protocol) to distribute VPN routing information through the carrier backbone network, and uses Multiprotocol token switching (MPLS) to forward VPN traffic between the VPN user sites. The main purpose of thi

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

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

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

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
