Learn about anatomy of internet routing protocol, we have the largest and most updated anatomy of internet routing protocol information on alibabacloud.com
internet lines, they need to load balance and routing routes, routers backup (VRRP is also mainly designed for this requirement) In order to be able to guarantee the uninterrupted and stable operation of the network, VRRP is a best choice, VRRP is the abbreviation of Virtual Router Redundancy Protocol Redundancy Protocol
switched over. I did it through a simulated public network, If it is a public network, default routing and NAT address translation must be performed on routers (RA) and RB to meet the requirements of the Internet on the Intranet. View the HSRP (SHOW) command: show standby 172 brief (view the HSRP configuration) Tip: The HSRP protocol is a proprietary
In IPv4, you must manually set the gateway address. The IPv6 protocol consists of two types of ICMP6 packets: RS and RA. The protocol is used to help nodes in the LAN find gateways or routers, so that the nodes can communicate with the Internet. On the other hand, for new IPv6 nodes that just access the network, you can set your own IPv6 address based on the gate
With the proliferation of the Internet, security has always been a top priority. At present, although the emergence of IPv6 routing protocol can solve the security issues under the IPv4 network protocol version, it introduces the updated security issues. Then, let's take a look at the specific content through the follo
This article describes in detail how to crack the CEN route and how to escape the detection of network leaders. I believe this article will help you. Internet sharing solution cracking China Netcom electric envelope Routing Currently, most broadband routers support functions such as "MAC address cloning" and "host camouflage mode", which can convert a router into a single connected device, this breaks throu
Achieve Internet sharing without routing The Internet can be shared without routing. Many people blindly think that only routes can be shared. In fact, this is not the case, in many cases, you can immediately share one network with two or more computers after simple settings. The sharing condition may be simply a simpl
The topology is as follows: The simple way to provide Internet access for the CE router is to let the interface on the PE connected to the CE router be in the global routing space, the PE router has a VRF interface pointing to the CE router, and an interface to the CE router but not the VRF. Then the CE router can send VPN traffic to the VPN interface and send the In
With the development of China's routing industry, it has also promoted the wide application of Internet cafe routers. Here we mainly explain the special technology of Internet cafe routers, so that Internet cafe routes are not dropped. As we all know, if you want to access the Inte

are playing in this group. Of course, if the router does not receive any reply after sending the query packet several times, it considers that all the hosts of the multicast have left silently, and it will reclaim the network segment. Note: If the host does not exist in version 1, click "Leave Group messages" Appendix: 224.0.0.0 ~ 224.0.0.255 is the reserved multicast address (Permanent Group address). The address 224.0.0.0 is retained without allocation. Other addresses are used by the
Currently, Internet-based applications of Internet cafe users have expanded from simple web browsing to more extensive fields such as QQ chat, VOD on demand, online games, education and training, and IP phones, the increasing number of these applications puts forward higher and higher requirements on the speed and stability of the network.

the two-protocol stack is running, it does not mean that the network and application-oriented services can be integrated into one another, and from the actual process of connecting the site, this work is much more complicated than it looks. DNS servers need to be queried, packets need to be able to pass through routing, TCP sessions need to be initiated, and packets need to be exchanged at all times. For

Some applications that continue to download can be grouped into a custom protocol group.2) IP classification, the establishment of different IP groups, different groups
There are two common ways of Internet access through ADSL: server sharing and router sharing. If you don't want to waste a computer as a server, you can check whether your ADSL Modem has the routing function (the instructions are provided ), if the ADSL Modem with the routing function is used, the Modem itself can be used as a host. Let's take a look at the speci

It first to determine whether the 4th computer is in the same subnet, the results found not (after the introduction of the method of judgment), so the packet sent to Gateway A. Gateway A through the routing protocol, found that 4th computer is lo
under TCP and UDP provide different port numbers, these features can be added to a single application (or databases used by those applications. Similarly, the IP address is designed based on the idea of treating the network below it as a black box, so that it can be considered as an independent layer when discussing TCP/IP. 4 Application Layer(OSILayer 5 to Layer 7) Such as HTTP, FTP, DNS(For routing protocols such as BGP and rip, alth
