Make sure that you have all the routing tables on display on one side (as before). As you go through the steps, look at the changes happening in the routing tables. Step 1: On all the routers, do the following. Router#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#no router rip Router(config)#exit Router# %SYS-5-CONFIG_I: Configured from console by console Router#copy running-config startup-config Destination filename [startup-config]? Step 2: Copy the image of the routing table for each router. Step 3: For Router RTA, Click the CLI tab. Copy the following text into the command line interface. RTA# configure terminal Enter configuration commands, one per line. End with CNTL/Z. RTA (config)#router ospf 1 RTA (config-router)#network 172.16.224.0 0.0.1.255 area 0 RTA (config-router) #network 172.16.230.0 0.0.0.3 area 0 RTA (config-router)#network 172.16.230.4 0.0.0.3 area 0 RTA(config-router)#end RTA# copy running-config startup-config Destination filename [startup-config]? %SYS-5-CONFIG_I: Configured from console by console Building configuration... [OK] RTA# Task 3.1: paste the image of RTA's routing table here. Task 3.2: a. Does RTA have a path to ALL the different subnet? b. Try pinging the different PCs and jot down your results. Table 6 Successful Unsuccessful () (x) 1 3 Ping between devices PCA-PCB PCA-PCC PCA-PCD Step 4: Configure the other routers with OSPF routing algorithm. Step 4.1: For Router RTB, Click the CLI tab. Copy the following text into the command line interface. RTB# configure terminal Enter configuration commands, one per line. End with CNTL/Z. RTB (config)#router ospf 1 RTB (config-router)#network 172.16.226.0 0.0.1.255 area 0 RTB(config-router)#network 172.16.230.0 0.0.0.3 area 0 RTB (config-router)#network 172.16.230.8 0.0.0.3 area 0 RTB(config-router)#end RTB# copy running-config startup-config Destination filename [startup-config]? %SYS-5-CONFIG_I: Configured from console by console Building configuration...

RTD(config)# RTD (config)#router ospf 1 RTD (config-router)#network 172.16.229.0 0.0.0.255 area 0 RTD(config-router)#network 172.16.230.12 0.0.0.3 area 0 RTD(config-router)#end RTD# RTD# copy running-config startup-config Destination filename [startup-config]? Building configuration... [OK] RTD# %SYS-5-CONFIG_I: Configured from console by console Step 5: Copy the image of the routing table for each router and paste it here. Step 6: Switch off router RTA. What are the changes noted in the routing tables? Step 7: Switch on router RTA. Wait a few minutes. What are the changes noted in the routing tables?
