Lab 7.1 routing analysis 3
Step 2. Again on each PC, ping the IP address of each PC’s respective default gateway. Record whether the ping worked or not in Table 5. Each ping to the PC has worked to the default gateway.

Step 3. From each PC, ping the IP address of the other three PCs. Record the results of each ping in Table 6 with a check mark for a successful ping and an X for a failed ping. None of the PC’s pinged to the other pc’s.

Step 5. From each router’s user mode command prompt, ping the IP addresses of each other router. Make notes about which IP addresses can be pinged from each router. Each router has pinged the other routers IP’s on the common LAN subnet but none of the pings worked from a router to each others routers.

Step 6. Use the show ip route and show ip routes ospf commands to examine each router’s routing tables. Do any of the four routers know any routes other than connected routes? Do any of the routers know any OSPF-learned routes? None of the routers have any OSPF routes. This is one of the reasons why the PC’s cant ping the other routers.

Step 7. From each router, use the show ip ospf neighbor command to discover with which other routers each router has formed a neighbor relationship. List the router pairs that have formed any kind of neighbor relationship on the lines below. None of the routers have OSPf neighbor relationships with the other routers.

Step 8. From each router, use the show ip ospf interface command to list the interfaces on which OSPF has been enabled. Does it appear that OSPF has been enabled on both interfaces on each of the four routers? List any routers and interfaces on which OSPF should be enabled but is not. OSPF has been enabled on both of the LAN interfaces on each router.

Step 9. On the lines below, make a list from memory of everything that can prevent OSPF routers from becoming neighbors. They must be
