The loop has a great impact on the network. Spanning Tree protocol is a good solution to this problem.The idea of spanning a tree protocol topology is that, regardless of the physical connection between switches, the switch can automatically discover a network with no loop topology, and the network of the logica

Tags: process proc ima RAC Technology share static term ADOBy configuring static routes, you can achieve an increase in routing entries for routers in a relatively simple network.However, if there are more than 20 routers in a network, it is difficult to configure static routes to accommodate the complexity of routing entries and changes in the network. At this point we can use the RIP protocol to configure simple dynamic routing, thus reducing the workload.Configuration ideas1 Configure the IP

Nat[network address translation] In the absence of IP address in the case of a great use, it can not be normal Sisu network of the intranet address into a legitimate external network address on the public network to send and receive data. At the same time address translation function can also be very good to hide and protect the host network.Nat has static NAT (internal address and external address one-to-one) and dynamic NAT (internal address pool and external address Pool A-do)This time we'll

Network address port Conversion NAPT is a very familiar way of transformation. NAPT is commonly used in access devices, which can hide small and medium-sized networks behind a legitimate IP address.Unlike dynamic address NAT, NAPT maps An internal connection to a separate IP address in the external network, adding a TCP port number selected by the NAT device to the address.This time, let's get to know napt.Configuration ideas1 Configure the router's interface IP address, note the network segment

RIP protocols can be configured in a more convenient way, but the limitations of RIP itself indicate that it is not suitable for medium to large networks. In contrast, OSPF is more complex to configure than RIP, but its functionality and performance are better than RIP.Configuration ideas1 Configure the physical interface address of the router Xia Lian switch and the physical interface address of the router to the other router and open the port2 Configure the address of the switch Xia Lian PC an

Through the previous experiment we learned that by configuring VLANs, the terminals under different VLANs could not communicate with each other, but if you wanted to communicate between different VLANs, you would need to configure inter-VLAN routingLayer three switches have the capability of the network layer and can be forwarded via the routing functionNetwork environment1 set the IP address and gateway of the terminal (192.168.1.1 and 192.168.2.1, respectively).2 VLAN is configured under Layer
