MPLS, IPSEC, and SSL analysis MPLS leased line MPLS (Multi-Protocol Label Switching), Multi-Protocol Label Switching. * Multi-Protocol refers to MPLS's support for multiple network layer protocols, such as IP, IPv6, and IPX. It is also compatible with multiple link layer technologies, including ATM, frame relay, Ethern
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
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
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
reduced.Scalability: Like ATM/fr vpn, VLAN + ACL is configured with N-square, each time a new VLAN or business system is added, the configurations of all previous business systems must be modified, resulting in serious scalability problems. When a new node or VPN is added to an mpls vpn, the existing VPN configuration is not affected and the scalability is excellent.Security: because all VLANs in the same broadcast domain have serious security proble
.25 and appeared as a new technology. it is mainly reflected in the data link layer. however, not only does ATM appear in The data link layer is also extended to three layers, and also to the user's desktop, but it also has very high requirements. It imposes limits on the configuration performance of network devices and network terminals, therefore, it has not been widely used. It uses fixed cells to forward data, which is highly efficient. VPI/VCI is applied during the exchange, similar to the

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 (
Protocol Stack chip implantation is imperative, IPSec is an error, and ipsec is imperativeThis article is a bit extreme, but may also cater to some people or organizations. This article is short. I will continue to write this topic later. The heart is too painful and the person is too weak.1. Protocol Stack chip ImplantationIf you think that protocol stack chips are consuming materials and eliminating costs
Brief Introduction
When you create an IPSec policy, you need to configure the IPSec rules that determine the behavior of IPSec and the settings that are not applied to the configured rules. After you configure the IPSEC policy, you must assign the policy to a computer to enforce the policy. Although multiple
I have been busy a few days ago for my livelihood. Unfortunately, I got sick for a few days, so I didn't keep the documents in time. I would like to apologize to everyone, especially those who are eager to wait for me to write a book.
Finally, I started to talk about the IPSec VPN technology. I have explained the principles of ssl vpn and mpls vpn. I still want to introduce the
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.
