CCNA 200-125 1.9: Configure, verify and troubleshoot IPv4 addressing and subnetting (LAB)

Review Cisco's subnetting best practices if necessary before attempting this lab.

PacketTracer Lab: CCNA-200-125-Lab-1.9.pkt

  • Subnetting and Troubleshooting
    • Subnet 192.168.10.0 into two /29 subnets and one /30 subnet. ¬†There will be more IPs in the network range after subnetting.
    • The client machines are already configured with the appropriate IP settings.
    • From the Marketing client, ping its loopback address 127.0.0.1.
    • From the Marketing client, ping its local IPv4 address 192.168.10.2.
    • From the Marketing client, unsuccessfully ping the gateway address 192.168.10.1.
    • Configure the first usable IP from the first /29 subnet on Router1 Fa0/0. ¬†Use the classless subnet mask.
conf t
        interface f0/0
           ip address 192.168.10.1 255.255.255.248
    • From the Marketing client, successfully ping the gateway address 192.168.10.1.
    • From the Engineering server, ping its loopback address 127.0.0.1.
    • From the Engineering server, ping its local IPv4 address 192.168.10.10.
    • From the Engineering server, unsuccessfully ping the gateway address 192.168.10.9.
    • Configure the first usable IP from the second /29 subnet on Router2 Fa0/0. Use the classless subnet mask.
conf t
        interface f0/0
           ip address 192.168.10.9 255.255.255.248
    • From the Engineering server, ping the gateway address 192.168.10.9.
    • Configure the first usable IP from the /30 subnet on Router1 S1/0. Use the classless subnet mask.
conf t
        interface s1/0
           ip address 192.168.10.17 255.255.255.252
    • Configure the second usable IP from the /30 subnet on Router2 S1/0. Use the classless subnet mask.
conf t
        interface s1/0
           ip address 192.168.10.18 255.255.255.252
  • From R1, ping the IP address of Router2 S1/0.
  • From the Marketing client ping the Engineering server 192.168.10.10
