Requirement:
  • Configure IP addresses as per diagram
  • Configure loopback addresses as per diagram
  • All routers must reach every route in the network
  • How many virtual links and tunnels we need to configure for this topology so that R8 will have all routes and why?
    1. 1 virtual link
    2. 2 virtual link
    3. 1 virtual link and 1 tunnel
    4. More then 2 virtual links
  • Test connectivity by ping
  • How many pings do we need to reach all networks from R8? Can pinging 255.255.255.255 will help us reach all networks in one go? If yes Why and If no then why not?
  • Verify configuration by using following commands
    1. Show ip route
    2. show ip eigrp interfaces
    3. show ip eigrp neighbors
    4. show ip eigrp topology
    5. show ip eigrp traffic
    6. show ip protocol
    7. show ip ospf border-routers
    8. show ip ospf database
    9. show ip ospf interface
    10. show ip ospf neighbor
    11. show ip ospf virtual-links
    12. show ip rip database
