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

Premise: With the development of the network, network security has become an important topic at present. More and more companies will choose to use the firewall as the company's egress device. Compared with the router, the firewall not only has the forwarding routing function, it can also filter internal and external traffic to further enhance the security of the company's network.

Technical standards for VLANs IEEE 802.1Q was formally promulgated by IEEE Commissioners in June 1999, and the earliest Vlna technology was proposed by Cisco (Cisco) companies in 1996. With the development of the past few years, VLAN technology has been widely used in large and small enterprise networks, becoming the most popular Ethernet LAN technology at present. This article is going to introduce one of

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.
