Several logos need to be created over the past few days. Unfortunately, I am not an artist. I would like to recommend a friend (sitting next to me) website for the artist. The artist is not very good but has powerful functions: meiwa ~ Xixi online

VPN clients can be provided Internet access by forwarding the traffic of the VPN user to the ISP's Internet network management.
Implemented by creating a static route in the VRF of the PE router and specifying the next hop in the global routing
We break down the Multi-Protocol Label exchange technology into several major elements, hoping to help you understand the working principles of this technology. To facilitate understanding, we will use an interesting analogy to describe how the

As shown in figure 1, the original IP private network in industry a is transformed and upgraded to become a network service platform, providing network services for multiple industries at the same time. There are similar demands in Politics and Law networks and e-government affairs networks. How to provide a logically isolated, secure, and reliable virtual IP private network for various industries has become a technical proble

switch connects to the aggregation switch through multi-link bundling. On the one hand, it can completely avoid second-layer loops and make full use of the uplink bandwidth of the access layer. Note that STP should be enabled even in L2 Networks without loops to prevent errors in device configuration and physical link maintenance. At the same time, although the network does not have a loop, STP may still affect the L2 network across multiple data centers. For example, when the network topology
At present, PE routers are widely used. They are one type of VPN routers. So I have studied the explanations and principles of PE routers and will share them with you here, I hope it will be useful to you. VPNVirtual Private Network (VPNVirtual Private Network) is a virtual Private Network based on public networks. It uses tunneling, encryption, and other technologies to provide users with a sense of direct connection to the Private LAN.
Introduction to MPLS
The display cpu-usage command is used to view statistics about the CPU utilization of the device and the CPU utilization of each process.Each process is described in detail below, with different software versions, boxed and boxed CPU processes slightly different, detailed information can be viewed in the manual reference, the display cpu-usage command introduction.

At present, the virtual routing domain technology is also widely used. Here we mainly introduce the virtual routing domain technology, this section describes how to use vro domain technology to implement VPN and further explores vro domain technology. At present, most cities have already built IP Broadband man networks, and many cities have also expanded their man networks twice or three times. The most popular construction method is to use routers and switches to form a backbone communication n
