To ensure the security of the network environment, we need to set up a verification mechanism in the network environment, that is, when a user's device wants to communicate with your device, it must pass your authentication. Today, let's take a look

[Lab environment] Cisco Packet Tracer 5.3.2 [PURPOSE] Exercise the use of the ip default-network command to declare the default route in the network routing protocol. [Experiment topology] [Lab description] Vrogw GW and ISP refer to the default

 The OSPF (Open Shortest Path First) protocol is a link-state routing protocol class. For IPV4 OSPF Current version number OSPFV2, the version number of John Moy is introduced in RFC 1247 and is updated in RFC 2328. In 1999, the OSPFv3 for IPv6

1. Add modules to several routers and configure ip addresses for PCs.At the same time, I am used to adding modules to the vro. the commonly used ports are s0/0/0.It is a 2811 vro. The topology of www.2cto.com is as follows: 2. Configure several

The link status update (LSU) packet is used for OSPF route update. An LSU packet may contain 11 types of link status notifications (LSA). The difference between the terms "link status update (LSU)" and "link status notification (LSA)" is sometimes

Open the CD with the book in the 6th Chapter practice "The OSPF and EIGRP route redistribution. PKT", the network topology as shown in Figure 6-24, routers and computers in the network have been configured according to the address configuration of

The OSPF on the broadcast Multi-Channel Access link starts the OSPF process on each device on the broadcast Multi-Channel Access link according to the parameters in. Here, I only use R1 as an example to describe how to enable the OSPF process:

OSPF tutorial steps:Set Area 1 to Totally Stubby Area, Area 2 to non-completely ending Area NSSA, and optimize the route table R1：   Router(config)#router ospf 10   Router(config-router)#area 1 stub  R2：   Router(config)#router 

The OSPF (Open Shortest Path First) routing protocol, which uses Zebra for OSPF experiments, is a link-state technology and is the most widely used and optimal performance protocol in IGP, it solves the large and scalable network requirements that

Switch requirements 1. Switch to restore factory settings and its basic configuration. 1)//Enter privileged mode 2) del Config.text 2. Telnet mode to manage the switch. 1)//Enter the global configuration mode 2) enable password 0 [password] 3)

Dynamic and robust routing is extremely important for Internet networks. Therefore, any network engineer who is first involved in this field must not only understand the concept of routing, but also be able to control it in a real environment.
