Note: This activity and the similar Packet Tracer – Skills Integration Challenge – EIGRP activity are meant as resources for you to determine what skills you may not have yet mastered from the previous courses. Refer to your notes and previous content if you need assistance. But it may be fun initially to see just how much you retained.

Your business has just expanded into a different town and needs to expand its presence across the Internet. You are tasked with completing the upgrades to the enterprise network, which includes dual-stacked IPv4 and IPv6, and a variety of addressing and routing technologies.
Note: Although not required, adding additional labeling to the topology may help you as you proceed. All names and passwords are case-sensitive.
Basic Device Configuration
• Configure the following on R1 and R4.
– Set the device names to match the Addressing Table.
– Set cisco as the encrypted privileged EXEC mode password.
– Set a banner MOTD which includes the word warn.
– Set the IPv4 and IPv6 addresses according to the Addressing Table.
– Assign the link local address to each interface.
• Configure SSH on R4.
– Set a domain name of R4.
– Create a user of admin with an encrypted password of cisco.
– Create a 2,048-bit RSA key.
– Configure all vty lines to use SSH and a local login.
• Configure R4 to act as a DHCP server for its LAN.
– Create a DHCP pool using the name R4.
– Assign the appropriate addressing information to the pool including the as the DNS server.
– Prevent the address used by the router from being distributed to end devices.
• Configure NAT/PAT on R4 so that all devices on the LAN use the IP address on the Serial 0/0/1 to access the Internet.
– Use a single statement in access list 1 to define the addresses that will participate in NAT. Allow only the address space.
– Enable NAT/PAT using the access list.
– Configure the appropriate interfaces as NAT inside or…

  • Hi,
    the problem you had was that when you were configuring the OSPF it should be done on R1 instead on R4. The good thing is that when you were explaining that part, you were referring to the R1 router on packet tracert. However, your configuration was on R4.
    Also on OSPF, the wildcard mask on network should be because the subnetmask is By mistake, the first time on R4 you put and the second time when correcting on R1 you also put the wildcard mask of
    Overall, thank you for your all videos because I learned a lot from you.
