mpls vs ipsec

The simplest approach is to use a script to configure it step-by-step. I used a script written by Philplckthun, modified the way to get the server IP: the script file.Run under Ubuntu:sh setup. SHAfter the configuration configuration is complete, the server side is ready.Next the client I use Win7, but Win7 has a pit, that is, if there is a router attached, that is, behind the NAT, the default is not connected to L2TP. Found this post on the Internet to solve the problem. You need to modify the

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

is not mature, there are problems with multi-vendor interoperability, MPLS cross-AS or even cross-Area problems, VC Merge (VC merger) needs to be studied. However, at present, MPLS is the best solution to achieve network-based VPN and can implement traffic engineering. In the future, the possibility of adopting MPLS must be explored in the study of IP networks.

). VPDN is a virtual network built using the public network remote dialing method. A Virtual Private Line (VLL) is a virtual leased line used by service providers on the IP network. It simulates a virtual leased line through a tunnel. It is mainly used for secure and reliable VPN with QoS Assurance, the implementation protocols include IPSec, GRE, L2TP, and MPLS. VPRN uses IP facilities to simulate a dedic

machines is that I either want to provide a Server Load balancer function, or want to provide a backup function, to present only one IP address externally, that is to say, the roles and locations of IP nodes can be separated. In fact, VPN + NAT can be used to meet this requirement. For example, both Beijing and Shanghai backup centers can use 192.168.1.13 to indicate the role address (if you do not use a private address, you do not need to use NAT ), the VPN encapsulation policy determines wher

requested port. VPN support The VPN on the IP address is described in the router technology above. Possible protocols include L2TP, GRE, IP Over IP, and IPSec. The VPN support capability should also be concerned. Encryption Method The router may use the encryptor mechanism in VPN implementation or other conditions to ensure security. Router technology uses CPU to execute software algorithms, which usually affects forwarding efficiency. Some router te

network. Distance from the vector Multicast Routing Protocol (DVMRP) DVMRP is a multicast routing protocol based on distance vectors, which is basically developed based on RIP. DVMRP uses IGMP to exchange route data packets with neighbors. Protocol-Independent Multicast Protocol (PIM) PIM is a multicast transmission protocol that can transmit multicast data over existing IP addresses. PIM is a multicast protocol independent of the routing protocol. It can work in two modes: intensive mode and

attacks. However, this network construction and maintenance costs are obviously high, therefore, this method is not desirable. In recent years, with the maturity of VPN technology, it has been feasible to build different VPNs on the same physical network, VPN technologies such as MPLS and VLAN can be used to divide an independent logical network from the physical network of grouped data into NGN virtual service networks, logically isolating NGN from
