MikroTik RouterOS is a routing operating system developed based on the Linux core and compatible with x86 PCs. It turns a common PC into a high-performance router and has been transplanted to the MikroTik RouterBOARD hardware plat
An employee of a company often lingers on the Internet instead of the Intranet OA. Recently, the boss asked to implement it. to access the Internet, you must log on to Oa first. One is convenient for attendance, and the other is limited for employees to access the Internet. In order to achieve this goal, an environment is set up and the test is successful!
Before you log on to Oa, open any website and go to the OA logon interface. The Internet is only available after you log on to Oa. Use the

This is the basic XXX configuration is complete.Things to note are as follows:XXX User network segment is not the same as the intranet segment.Problem 1,XXX cannot access the public network after
Companies in China, Japan, the United States, Germany, Singapore and many other businesses have business, intermediary business Network with the company's proprietary GPN (Global Private Network Chinese name is the world's privatization networks) link, the current test to build a backup link for network redundancy and failover.The initial selection program is GRE over IPSEC, which runs the OSPF routing protocol.First, why to choose GRE over IPSEC:
Each site network is more, need to use
Rd and RT (mpls vpn bgp)
Rd (route-distinguisher) is used to identify different VPN instances on the PE device. Its main function is to achieve address multiplexing between VPN instances. It and the IP address constitute a 12byte vpnv4 address space, rd and the route are carried together in the bgp update message and published to the peer end. On the one hand, we need to verify whether the RD function is implemented, whether the PE device can achieve
This document mainly explains the following:
MPLS header structure and the role of each primary field.
How the tagged message is forwarded
Keep the MPLS tag names, as well as their role.
Determines the importance of MPLS MTU in MPLS networks.
In MPLS, they are exchanged
MikroTik RouterOS-common configuration commandsMikroTik RouterOS is a routing operating system developed based on the Linux core and compatible with x86 PC routing software. Through this software, standard PC computers are converted into professional routers, in the development and application of the software RouterOS soft routing diagram, the software has undergone many updates and improvements, so that its functions are constantly improved and impro

MPLS Multiprotocol Label Switching-Multi-Protocol Label exchange technology is a new technology that uses tags to guide high-speed and efficient data transmission on open communication networks. Its value lies in its ability to introduce the connection mode in a connectionless network. Its main advantage is that it reduces network complexity, is compatible with various mainstream network technologies, and can reduce network costs by 50%, ensure QoS an
Mobile data is one of the most promising Telecom businesses. It can meet the needs of various mobile terminal users to access the Internet anytime, anywhere, it can also meet the needs of data and multimedia communication between them. Mobile IP is one of the key technologies to implement mobile data services. It supports mobile terminals with fixed IP addresses to move freely on the Internet and keep communication uninterrupted during the mobile process. Multi-Protocol Label Switching (
Networking requirements:1. Configure the basic information of each vro2. Configure OSPF specifications and change the network type to point-to-point3. All routers run OSPF, RT4 E3/0, RT5 E3/0 network to OSPF, RT1E3/0 re-publish directly to OSPF4. All routers run MPLS, And the Label Distribution Protocol is LDP.5. Run IBGP in RT4 and RT5 and publish E3/1 to BGP.Previous ConfigurationThe IGP configuration is as follows:RT1:Router ospf 1Router-id 1.1.1.1
With the continuous development of global network facilities, a large part of the network field has recently switched to the use of Multi-Protocol Label Switching (MPLS), which simplifies the virtual private network (VPN) link, implementing service convergence and traffic engineering offers attractive opportunities while minimizing complexity and overhead related to earlier methods.

In the course of the development of IPOA technology, CIPOA (Classic IPOA, that is, traditional lP on ATM), LANE (LAN simulation), and MPOA (Multi-Protocol Transmission on ATM) emerged one after another) IP address switching, CSR (cell Switch Router technology), ARIS (Integrated IP address switching technology), TapSwitching (Label Switching Technology), MPLS and other technologies. These IPOA technologies can be divided into two types: overlapping mod
MPLSMultiprotocol Label Switch (MPLSMultiprotocol Label Switch) was originally proposed to speed up router forwarding, but because MPLS is used in Traffic engineering Traffic Engeering) and VPN are two key technologies in the current IP network. MPLS has become an important standard for expanding the IP network scale.
The key to MPLS protocol is to introduce the
, rich function and private network security, flexible, efficient combination, not only can reduce the user network equipment investment and line, reduce the user's monthly communication expenses, At the same time, the use and maintenance of the network become simple, easy to manage and expand, reduce the network operation and management of human and material costs.Netcom MPLS VPNMPLS VPN belongs to one of the Ip-vpn.

MPLS routing protocol is one of the most common protocols in the process of using a router. Many people may not understand the basic concepts of MPLS routing protocol. It doesn't matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. MPLS routing protocol (Multiprotocol Label Switch) was initial
I won't talk about the configuration. Read the previous blog!1. propagation of CE and pe vrf private networksThe IPV4 route in the CE global route table is transmitted to the corresponding VRF route table of PE through the routing protocol (such as RIP, OSPF, OSPF, and BGP) between PE-CE. On PE, the routing protocol (Routing Protocol process or routing protocol instance) for routing exchange with CE must be bound to the corresponding VRF. On the bound VRF interface, only the VRF routing protocol
