Lab 4-1: Routing Table Interpretation (4.6.1)
Upon completion of this lab, you will be able to
Interpret router output
■
Identify the IP addresses for each router
■
Draw a diagram of the network topology
■
Cable and configure a network based on the topology diagram
■
Test and verify full connectivity
■
Reflect on and document the network implementation
■
Scenario
In this lab activity, you must re-create a network based only on the outputs from the
show ip route
command. Match the addresses to the corresponding interfaces and enter the information in Table 4-3.
Configure the routers and verify connectivity. When complete, the outputs from the
show ip route
command must be exactly the same as the supplied outputs. The
show ip route
command displays the
current state of the routing table.
Task 1: Examine the Router Output
Examine the output from the HQ router.
Step 1.
HQ#
