There are many other things worth learning about the vro protocol. Here we mainly introduce the features of IS-IS, including the features of the Border Gateway Protocol and BGP. While IAB works on OSPF, ISO works on IS-IS. At the end of 1980s and the beginning of 1990s, each person in the Open Systems Interconnection (OSI) group could replace TCP/IP. At that time, the integrated IS-IS was proposed. Although IS-IS was originally used for the OSI Router

to discontinuous and distorted signals. To solve these problems, the vendor provides several solutions: the first solution is based on the priority of different objects, and data packets sent by some devices (mostly multimedia applications) can be uploaded first. The second scheme is based on the protocol priority. You can define which Protocol has a higher priority. The protocol can be uploaded first. Both Intel and Cisco support this scheme. The third solution is to implement Multi-Link Point

Many people may be familiar with the term Router Protocol, especially the rapid development of the network, the Internet Router Protocol is constantly improved, and many new features are also emerging. The wide application of information technology in various fields has promoted the rapid development of information exchange networks. Internet is the biggest beneficiary. The main node and device of the Internet network are routers. The router technology determines data forwarding through routing.

For the term router protocol, probably a lot of people have been familiar with, especially the current network development quickly, Internet Router Protocol is also constantly improving, but also appeared a lot of new features. The wide application of information technology in various fields has promoted the rapid development of information exchange network, in which the Internet is the biggest beneficiary. The main node device of the Internet network is the router, which determines the forwar

, and BGP protocols A large number of routing protocols running on the Internet are RIPRouting Information Protocol-Routing Information Protocol), OSPFOpen Shortest Path First-Open Shortest Path First), and BGPBorder Gateway Protocol-Border Gateway Protocol ). RIP and OSPF are internal gateway protocols and are applicable to the operation of unified routing protocols of a single ISP. A network operated by an ISP is called an autonomous system.

How DCN and SDN meet new requirements New Technology of ip ran Network The traditional 3G/B3G network needs the basic bearer network to provide the Layer 2 capability to meet the needs of the Upper-layer network mobile service return. However, due to the introduction of S1-Flex and X2 interface, the basic bearer network must have three-layer switching capabilities. Based on the dynamic IP/MPLS protocol and key technologies, the ip ran is a solution that combines Layer 2 and Layer 3 technologies

This article describes the basic working principles of routers in TCP/IP networks, introduces several functions of IP routers, and provides Static Routing and dynamic routing protocols, as well as the concept of the internal gateway protocol and the external gateway protocol, and briefly introduces the most common RIP, OSPF, BGP and BGP-4 routing protocols, then, it describes the design objectives and types

are a shared bandwidth, at the same time only two ports to transmit data other ports can only wait, while the hub only works in half-duplex mode, and for the switch, each port has an exclusive bandwidth, While two ports work without affecting the work of other ports, the switch can operate in half-duplex mode and work in full-duplex mode.4.

. Forwarding is the best path for transmitting data packets along the path finding. IP route selection methods include static and dynamic routing, direct and indirect routing, single-path and multi-path routing, hierarchical routing and non-hierarchical routing, intra-Domain Routing and domain query routing, and distance. vector routing and link status routing. Routing selection using RoutingAlgorithmTo calculate and determine the optimal transfer path to the destination. The routing protocol

router, that is, the Label Edge Router LER In the MPLS network ), it processes the VPN data from the CE router or the label exchange path LSP according to the stored route information and forwards the data. It is also responsible for exchanging route information with other PE routers; P router is the main router of the carrier network, that is, the label exchange router LSR In the MPLS network. It transparently forwards the VPN data according to the outer label of the group, the P router only m

industries are constantly merged and then merged. I wonder why we should not study the business model of the civil aviation industry. The separation of management right and experience right means that the airport manages the airport, the aviation business manages the aviation business, and the airport will only achieve a win-win situation, the aviation business will only compete, and the ultimate benefit is consumers.If the problem is incorrect, let's talk about this dual-line solution, The c

The loop port has a very wide application in practice, and this article is about the use of loopback mouth. BGP Update-source Because the loopback mouth as long as the router is still alive, it will always remain active, so as long as the BGP peer loopback to meet the route can be reached, BGP can be established, in general,

interfaces can still be telnet, that is, the TCP connection to this vro still exists. Therefore, the selected telnet address must never be down, and the virtual interface meets this requirement. Because this type of interface does not require interconnection with the peer end, the address of the loopback interface is usually specified as a 32-bit mask to save address resources. Use this interface address as the router id of the Dynamic Routing Protocol OSPF and
