Absrtact: Broadband IP metropolitan Area network, routing planning and design is the core link. In the beginning of the network, must be integrated planning. According to the construction of the metropolitan area Network, the routing strategy based on Bgp/mpls VPN is adopted, which is proved to be feasible by practice. Key words: BGP MPLS VPN IP Routing strategy 1 Broadband metropolitan Area Network overv

Article Title: How to manually create a tunnel in the RedHat environment. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. ▲Configure ipv6 on RedHat 　　 ① Re-compile the kernel: The current version of redhat supports ipv6 (all later versions of kernel after 2.0.x support ipv6), but it is not compiled by default.

OpenVPN-ng: The application-layer tunnel for Mobile Life, And openvpn-ng Application LayerVPN makes people think that it is always a good thing and a way to escape from supervision. In fact, VPN has become the only synonym for escaping from supervision. You see, no matter what technology, IPSec, or WEB Proxy, as long as it is the technology that encrypts the original information, it can all be called VPN, so there is a so-called layer-2 VPN technology

How does one access the Linux server after NAT through SSH reverse tunnel? (1) Suppose you are running a Linux server at home, which is behind the NAT router or restricted firewall. Now, you can connect to the home server through SSH when you are not at home. How do you do this? SSH port forwarding is undoubtedly a method. However, if you are dealing with multiple nested NAT environments, port forwarding will become tricky. In addition, because the s

In actual work, we often encounter the requirement to connect two local area networks in different locations. The use of FreeBSD IPSec tunnel method can easily connect two local area networks, and has good security. Here's a case to tell how to connect two local area networks in this way. Assume the following network structure: The two FreeBSD machines are configured with firewalls of two subnets, and IPSec support is added to the kernel configura

Release date:Updated on: Affected Systems:Quagga Description:--------------------------------------------------------------------------------Cve id: CVE-2012-0255 Quagga is a route software suite that can implement multiple routing protocols on Unix platforms. Quagga 0.99.20.1 when implementing BGP, ospfd does not correctly use messages for OPEN messages, resulting in DOS through messages related to malformed AS4 functions. Link: http://secunia.co

TCP/IP Note 2. Network Layer (2) -- ICMP, RIP, OSPF, BGP 1. ICMPICMP (Internet Control Message Protocol): improves the chances of successful IP datagram delivery. 1.1 features ICMP allows the host or router to report errors and reports exceptions. ICMP is not a high-level protocol, but an IP layer protocol. An ICMP packet is used as the data of an IP-layer datagram, And the header of the datagram is added to send an IP datagram. 1.2 format 1.3 packet

Border GatewayProtocol is a routing protocol that dynamically exchanges route information between autonomous systems. A classic definition of an autonomous system is a group of routers under the control of a management organization. It uses IGP and common measurement values to forward packets to other autonomous systems. The term autonomous systems are used in BGP to emphasize the fact that the management of an autonomous system provides a unified in

BGP routing is optimal, in the absence of filtering, there are two conditions related: Next hop can be reached, synchronous shutdown. If these two conditions are not met, the routing is not optimal.BGP Routing principle: If the next hop of this route is unreachable, this route is ignored Preferred-valnue value higher priority, Huawei Private attribute, only local meaningful Local-preference highest-Value routing priority Aggregation rou

Background: two lines used by our company, one of which is the MPLS line of China Telecom. We need to transmit the routes to the BGP Route of China Telecom, the BGP routing protocol of China Telecom is transmitted to the corresponding routing table of the headquarters.Symptom:Suddenly, the MPLS line of China Telecom was disconnected, and Netcare called to report the fault. I thought the optical fiber was di

The monitoring system has made new breakthroughs in the wireless age, especially in China. Our country has a complex terrain and a vast territory. We want to monitor tunnels in such a complex environment, wired monitoring is always limited, so the birth of the wireless monitoring system has injected fresh blood into the monitoring system. In the Monitoring System Application of the tunneling industry, the solution represented by the current wireless monitoring system is more practical and effici

Tunnel can be seen as the simplest form of VPN. Its parameters are simple as long as the Tunnel Source and Tunnel Destination parameters are configured. The following is an example of the configuration method: The topology is as follows: Create a Tunnel between R1 and R2 R1: S1/0: 192.168.1.1 F0/0: 192.168.10.1 Loop0:

Vpn Principle and Implementation-tunnel implementation theoretically reasonable ip over ssl needs some additional technical support before it can be used, you must try to re-encapsulate an ip data packet by ssl. This action cannot be performed in the original standard protocol stack. The standard protocol stack does not support two-way data flow, one of the solutions is to modify the Protocol Stack and implement a lightweight ssl protocol layer under

Recently, I debugged the public account function. when receiving the push, I didn't want to submit it to the server to view the log every time. so I used the reverse proxy of Nginx to forward the requests received by Port 80 on the server to 127.0.0.1: 9000 and then use ssh to build a tunnel to set the server's 9000... I recently debugged the public account function and didn't want to submit it to the server to view the log every time when receiving t

exists in a route, the RR will not create a new originator_id. (2) When other BGP speaker receive this route, they will compare the received originator_id and the local Router ID, if two IDs are the same, BGP speaker ignores this route and does not process it. The Originator_id property guarantees that the route does not loop between the reflector and the client/non client. Cluster_list is a 4 8-bit op

A key problem statement (a) How does the ACL match the same subnet and the different mask routing entries? How do I match the same mask, different entries for subnets? (ii) Why does a summary route cause the rollover of a BGP neighbor? (iii) Why does the ACL not match the route entry when using Attribite-map? (d) How to use Advertise-map,suppress-map,unsuppress-map,attribute-map and Route-map five-way map? Give an example. (v) The two schemes of

For network communication that requires encryption, there are many options, such as various VPN: L2TP/IPSec VPN, PPTP, SSL The following is a simple point-to-point IPSec tunnel, which is so simple that it seems that the Internet is not very large... Maybe I am not quite right. L2TP and various VPN gateways have found a lot... In this way, you can set the IP security policy of the Local Machine to perform security negotiation for specific network commu
