Activities[edit]

  1. Use the Tracert command to test network routing.
  2. Use the route command to display and modify the local routing table:
  3. Use a router emulator to set up and configure a basic router. (Note: The emulator will not save configuration changes.)
    • Under Setup, configure advanced routing.
      • Enable RIP.
      • Receive and transmit using RIPv2.
    • Add a static route to 192.168.2.0/24 using:
      • Destination IP: 192.168.2.0
      • Subnet Mask: 255.255.255.0
      • Default Gateway 192.168.1.2
      • Hop Count: 1
      • Interface: LAN
  4. Ask your school or business organization's IT personnel to describe the routing environment. What routers are in use? Which routing protocols are in use? Are any static routes in use? How many locations and how many subnets are managed by the routers?
