Background

In this Skills Integration Challenge, your focus is OSPFv2 and OSPFv3 configurations. You will configure IP addressing for all devices. Then you will configure OSPFv2 routing for the IPv4 portion of the network and OSPFv3 routing for the IPv6 portion of the network. One router will be configured with both IPv4 and IPv6 configurations. Finally, you will verify your configurations and test connectivity between end devices.

Note: This activity is graded using a combination of assessment items and connectivity tests. The instructions window will not show your score. To see your score, click Check Results > Assessment Items. To see the results of a specific connectivity test, click Check Results > Connectivity Tests.

Requirements

Use the following requirements to configure RA addressing and OSPFv2 routing:

  • IPv4 addressing according to the Addressing Table
  • Process ID 1
  • Router ID 1.1.1.1
  • Network address for each interface
  • LAN interface set to passive (do not use the default keyword)

Use the following requirements to configure RB addressing, OSPFv2 routing and OSPFv3 routing:

  • IPv4 and IPv6 addressing according to the Addressing Table
    • Set the Gigabit Ethernet 0/0 Link Local address to FE80::1
  • OSPFv2 routing requirements:
    • Process ID 1
    • Router ID 2.2.2.2
    • Network address for each interface
    • LAN interface set to passive (do not use the default keyword)
  • OSPFv3 routing requirements:
    • Enable IPv6 routing
    • Process ID 1
    • Router ID 2.2.2.2
    • Enable OSPFv3 on each interface

Use the following requirements to configure RC addressing and OSPFv3 routing:

  • IPv6 addressing according to the Addressing Table
    • Set the Gigabit Ethernet 0/0 Link Local address to FE80::3
  • OSPFv3 routing requirements:
    • Enable IPv6 routing
    • Process ID 1
    • Router ID 3.3.3.3
    • Enable OSPFv3 on each interface

Configure PCs with appropriate addressing.

  • PCA and PCB IPv4 addressing must use the last assignable address in the IPv4 subnet.
  • PCB and PCC IPv6 addressing must use the second assignable address in the IPv6 network and the link-local FE80 address as the default gateway.
  • Finish the Addressing Table documentation

Verify your configurations and test connectivity

  • OSPF neighbors should be established and routing tables should be complete
  • Pings between PCA and PCB should be successful
  • Pings between PCB and PCC should be successful

Note: If OSPFv3 has not converged, check the status of interfaces using the show ip ospf interface command. Sometimes, the OSPFv3 process needs to deleted from the configuration and reapplied to force convergence.
