The ospf protocol is run between R2, R3, and R4, and an IBGP neighbor is established between R2, R3, and R4 using a loopback port. Router bgp 100 no synchronization
There is very little on the web for the first time RouterOS to open a page to force jump home, most of the way is to browse the IP address of a domain name to your home page, this method sometimes fails.Another way is that when the user connects with Port 80, fetch the source address to the address list, and then specify the timeout time of the address, do address mapping to achieve the purpose of forcing a jump, but this method will often fail, some

I carefully read the posts posted by netizens on the Forum and think that the problem of disconnection can be solved.The so-called cut-off: Here I define a cut-off as a phenomenon where online games are constantly playi

First, we must know how to log on to QQ:
UDP, destination port 8000 4000 = OICQ ClientTCP mode, destination port 80VIP mode, destination port 443
QQ servers are divided into three types:1. UDP 8000 Port Class 7: the fastes
I am doing a demonstration in the virtual machine. I hope you can use it as needed.
1. Prepare the toolOpen http://adelie.polymtl.ca/releases/x86/current/installcd/Find the ISO file to download. Because the file name is changed due to version changes, only the downloaded directory location is provided.
2. Directly engrave the ISO file, but do not engrave the disk or do not have a burner.
3. Shut down Ros and start it with the engraved disk. Wait for the livecd root to appear #

I tried to use a tool to crack it.
I searched the internet and finally found a practical articleArticle. After reading this article, I have a general understanding of the entire cracking process. in the past, ADSL users used the PAP protocol or Chap protocol in the PPP protocol for identity authentication. Since the PAP protocol uses plaintext to transmit key information, you only need to establish a pppoe server and use the PAP protocol for identity authentication, when the vro communicates
10. Conclusion
The BGP protocol provides high control and flexibility for Inter-Domain Routing, implements policy constraints, and avoids routing loops. The guidelines described here provide a starting point for BGP use. As BGP grows, it will provide more advanced and manageable routing methods.
Appendix A. Relationship between
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
BGPBorderGatewayProtocol) is the Border Gateway Protocol used to connect to independent systems on the Internet. It is an enhanced, comprehensive, and scalable protocol developed by the Internet Engineering Task Group. BGP4 supports the CIDR addressing scheme, which increases the number of available IP addresses on the Internet. BGP was designed to replace the original external gateway protocol EGP and is also considered a path vector protocol.

BGP Communities PropertiesThe community property of BGP is an optional transitive property, and routers that do not support this attribute pass the community value to the downstream BGP neighbor intact (provided the delivery community property is configured).The community attribute of BGP simplifies the matching of rou
In network protocols, the use of BGP is complex to many extent. This is caused by different IP addresses of different hosts, different network connections, different terminals and hardware interfaces. Therefore, there are many types of routing protocols in our network protocols. BGP is an external gateway protocol designed for TCP/IP Internet and used between multiple autonomous domains. It is neither based
1. BGP Route synchronization Concept
BGP protocol: A router running the BGP protocol will not advertise the routing information learned from the internal peer (IBGP neighbor) to the external peer (EBGP neighbor ), unless the route information is also known through IGP. If the BGP router can learn the route information
Border Gateway Protocol (BGP) is an Internet routing Protocol. BGP itself is not too complex, but those first involved in this field may be unfamiliar with this concept hidden behind Autonomous System routing. We hope that you can use this article to briefly understand the working principle of BGP and the problems it produces and can solve.
Through the last lectu
External Gateway Protocol: BGP (Border Gateway Protocol)
BGP: the protocol for exchanging route information between as routers of different self-made systems.
The Internal Gateway Protocol rip or OSPF is used to send a datagram to the target site from the source site as much as possible in an. However, the external gateway protocol uses different BGP environments
At present, there are also a lot of BGP routing protocol applications, so I have studied the synchronization problem in the BGP routing protocol. Here I will share it with you and hope it will be useful to you. BGP protocol: A router running the BGP protocol will not advertise the routing information learned from the i
BGP is a familiar protocol. Then, let's give a brief explanation of this Protocol. It mainly targets its synchronization performance. You need to pay attention to this aspect. BGP protocol: A router running the BGP protocol will not advertise the routing information learned from the internal peer (IBGP neighbor) to the external peer (EBGP neighbor ), unless the r
BGP is a path vector routing protocol. Its job is to exchange route information between autonomous systems to find the most effective path for accessing data somewhere on the Internet. How do I select the optimal route? Cisco borderless networks reveal 14 BGP routing principles:

BGP protocol overview * BGP autonomous system-AS is a group of centrally managed routers that use the same internal gateway protocol and unified measurement values in AS internal routing groups, and use the external gateway protocol to route the group to other. -- BGP is used to connect to the autonomous system and provide routes between AS-. *
