Learn about anatomy of internet routing protocol, we have the largest and most updated anatomy of internet routing protocol information on alibabacloud.com
. Supports VSLM with a variable-length subnet mask. routes can be seamlessly exchanged between the same autonomous system number and the IGRP. The configuration of VPN is roughly the same as that of IGRP: Routerconfig) # router eigrp100 indicates the autonomous system number)Routerconfig-router) # networkNetwork-number routerconfig-router) # exit OSPF OSPF is a link status routing protocol. The so-called li
interference, geography, environment, and other factors. From the above features, we can know that a complete wireless mesh network protocol must have the following features: Distributed operations Fast Convergence (to ensure faster movement) Scalability Suitable for a large number of small devices Use only limited bandwidth and computing power Proactive operations (Reducing Initial latency) When selecting a route, consider the quality and capacity o
When the routing protocol is enabled, the network has the powerful function of automatically updating the route table. However, some major internal gateway protocols (InteriorGatewayProtocol, IGP), such as RIP/RIP2, OSPF, or IGRP/VPN, have certain protocols. The Internal Gateway Protocol is applicable to scenarios where only one Administrator is responsible for n
number of Route Relay (hop) or route-related fees for the destination site on the network. At the same time, select the route table on the device for each route, it should contain roughly the same routing selection information. In the wide area network using the Remote Communication Link, regular routing selection is basic, but must be rapidly changed on the remote communication link (for example, Line Dis
, the routing method is actually Nat, in fact, the principle of routing and Nat is still different. We will not discuss it here. Currently, ADSL cats generally have Nat functions. It is more economical and convenient to use its own functions to achieve Internet sharing, this article mainly discusses this method.If you want to block more than one computer from acc
Note: There is no source code analysis in this article. However, I think it is more useful to understand the essence than to understand the source code, because after understanding the essence, you may not need to look at the source code again, you can even write the source code. This is why the Linux kernel and Cisco websites contain a large number of documents. Introduction: routing is a core concept of the Inte
Communication Protocol for TCP/IP Internet (Internet) I. TCP/IP is used for Internet (Internet) communication Protocol 1. Computer Communication Protocol is a description of the rules t
be manually executed by the user or by running the rc Script at startup. The above method involves Static Routing, which is usually created at startup and will not be changed without manual intervention. Static Routing Protocol Both the host and gateway can use dynamic routing technology, which allows the route table
With the rapid development of the Internet, the network scale expands rapidly, the amount of information is increasing rapidly, and new applications are emerging one after another, the original Network Interconnection protocol version 4 that has been developed for more than 20 years -- IPv4 protocol has insufficient address space due to its inherent defects, low
Open Shortest Path First (Open Shortest Path First) is a very active link status Internal Gateway Protocol (IGP). When people find RIP (route information Protocol) it cannot be applied to larger networks, and OSPF is adopted when the convergence speed is too slow. This article will give a general introduction to the OSPF protocol, and the next lecture on basic ne
In the network protocol, we have started to use the IPv6 protocol. Especially for mobile communication, IPv6 is also studied. Now we will describe the IPv6 Routing Protocol in mobile communication, hoping to help you understand this knowledge, in this way, we can have a deep understanding of our networks and communicat
) server by using Windows Server 2003来. The Windows Server 2003 Routing and Remote Access service includes the NAT routing protocol. If you install and configure the NAT routing protocol on a server that is running Routing and Rem
16 bits starting from the left end of the address. The introduction of CIDR simplifies Routes Aggregation ), route aggregation is actually a process of combining several different routes, so that the route entry is changed from advertised to advertised, reducing the route table size ｡ When a route is updated, the BGP routing protocol only sends updated routes, which greatly reduces the bandwidth occupied b
-UCSB is updated with Nerfilter. AODV-UCSB uses the AODV-UUv0.4's Netfilter kernel module. With these kernel modules, all the packets of interest can be processed through the user layer daemon process, as described in section2.3. In addition, the description of the basic Octa version is as follows, A large number of Hello messages are available. These include receiving a variety of Hello messages before the neighbor connection. This avoids routing to
It is very useful to know about dynamic routing protocols. Here we will mainly introduce the full explanation of OSPF dynamic routing protocols. Today, with the rapid development of the Internet, TCP/IP has become the mainstream protocol for data network interconnection. All kinds of routers running on various networks
Many of us know the IP protocol, that is, the Internet Protocol address. But it is also a datagram protocol. These basic structures are not clear to many friends. Next we will introduce the basic structure of this datagram. Internet Prot
1. Question proposal With the advent of the network information age, Internet technology has developed rapidly worldwide. Open Shortest Pass First (OSPF) dynamic Routing has become the preferred internal gateway protocol for network routing. In the transition from IPv4 to IPv6, OSPFv3 (Open Shortest Path First versi
HSRP is also a type of routing protocol. So what is the role of this protocol? What are the features? In this article, we will introduce some concepts and structures of this Protocol in detail. With the increasing popularity of the Internet, people are increasingly dependent
The routing protocol analyzer is still very important in routing applications, and the technology is gradually improved. The best way to analyze data packets transmitted over the network is largely determined by the device you have at hand. In the early stages of network technology development using the Internet era of
1. Introduction BGP is a routing protocol between autonomous systems. The Network accessibility information exchanged by BGP provides sufficient information to detect routing loops and make decisions based on performance precedence and policy constraints. In particular, BGP exchanges the network accessibility information of all as paths and executes
