1. Establish Topology

 

 

 

 2. Configuration Parameters

Click to enter ipconfiguration Pc into the PC configuration

 

 

Click clk into the router using the routing instructions to configure

　　• Use the command erase startup-config clear the existing configuration on the router:

　　• Router> enable # to enter the privileged EXEC mode

　　• Router # erase startup-config # remove existing configuration on the router

　　• Router # configure terminal # enter the global configuration mode

　　• Router (config) #no ip domain-lookup # Disable DNS lookup

 

Configure and activate port

　　• Router> enable # to enter the privileged EXEC mode

　　• Router # configure terminal # enter the global configuration mode

　　• Router (config) #hostname R # router name is configured to R

　　• Configure G0 / 0 Interface:

　　• R(config)#interface G0/0

　　• R(config-if)#ip address 192.168.1.80 255.255.255.0

　　• R (config-if) #no shutdown # interface to activate

 

 

 

 

 

 

 

 

 

3. Test

　　By PCping server

　　

 

 Use of the clk show interface brief check communication state

When the off period of the routing path

 

 Bad news travels slowly rip

　　Analyze the reasons is that when the bad news started router does not know the bad news and good for the current state and continuously update its own routing table (router here is 29s to update the current routing table from time to time), so that the longer distance until delivery exchange of routing information indicates the current status of the router to know when bad "bad news" appears.
