OSPF Challenge Lab
Topology
Once you have logged in, scheduled the correct lab, and hit Enter Lab you will see the following:
Instructions
The challenge lab includes configuration content from the reading and labs you have worked on to this
point in the course. Refer to the topology diagram and complete the configuration tasks as outlined below.
Verify whole topology is operational and functioning properly.
Step 1 - Subnetting:
The interfaces and PCs have not been assigned IP addresses in the topology, you need to figure out the
subnets and IP addresses to use. In order to configure the IP addresses on the interfaces and PCs you
need subnet the 192.16.20.0 network.
Begin by figuring out how many networks you need for this topology. Then subnet 192.16.20.0 /24 to get
enough subnetworks and usable host addresses to configure this topology and achieve complete
connectivity.
Step 2 - Configuration Tasks:
Configure Hostnames according to the topology
Configure Enable Secret, Telnet and Console passwords. Set all of the passwords to uwstout
Configure the interfaces with IP addresses and subnet masks according to the topology and the subnetting scheme you came up with in Step 1.
Configure the Clockrates on the DCE interfaces to 128000
Configure the Bandwidth on the DCE interfaces to 128
Configure the OSPF routing protocol in the areas shown in the diagram
Configure OSPF Authentication
Configure the IP address, Subnet Mask and Default gateway on each PC
Verify all networks are each router’s routing table
Verify connectivity by pinging from PC1a to PC2 and PC3.
If you do not have connectivity, troubleshoot. Begin with ensuring the interfaces or “up, up” work your way through verifying the IP addresses and routing protocol configuration.
Step 3: Saving Configuration Once you have completed the lab save your configurations.
