CISCO PT Simulation Experiment (14) router configuration for OSPF dynamic routingExperimental Purpose :Mastering the configuration method of OSPF dynamic route selection protocolMastering the OSPF route description in the routing tableFamiliar with the principle and process
The OSPF protocol is very important for the use of Cisco routers. But how do I perform specific operations? The following article will give a detailed explanation. OSPF protocol operation: 1. the ROUTER that declares OSPF sends a HELLO message from all interfaces that start

This article describes in detail how to improve OSPF security for Cisco routers. This article describes how to improve network security in terms of protocol analysis and router authentication solutions. OSPF is also an open version of The Link Status Protocol. In practice, OSPF

Topology1. the device configuration is as follows: R1 (config) # int s1/0R1 (config-if) # ip add 192.168.1.1 255.255.255.0R1 (config-if) # no shutR1 (config-if) # int s1/1R1 (config-if) # ip add 192.168.3.1 255.255.255.0R1 (config-if) # no shutR1 (config) # line cons 0R1
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

It is very useful to know some knowledge about OSPF router protocols. Many people may not know the commands commonly used in OSPF router protocols and the explanations of some terms. It does not matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. A
