Task 4: Finish Configuring Router Interfaces

Configure the remaining R2 interfaces.

Step 1.

Finish configuring the remaining interfaces on R2 according to the topology diagram in
Figure 2-10 and the addressing information in Table 2-3.

Configure R3 interfaces. Step 2.

Console into R3 and configure the necessary interfaces according to the topology diagram
in Figure 2-10 and the addressing information in Table 2-3.

Task 5: Configure IP Addressing on the Host PCs

Configure the host PC2. Step 1.

Configure the host PC1 with an IP address of 172.16.3.10/24 and a default gateway of
172.16.3.1.

Configure the host PC2.

Step 2.

Configure the host PC2 with an IP address of 172.16.1.10/24 and a default gateway of
172.16.1.1.

Configure the host PC3. Step 3.

Configure the host PC3 with an IP address of 192.168.2.10/24 and a default gateway of
192.168.2.1.

Task 6: Test and Verify the Configurations

Test connectivity. Step 1.

Test connectivity by pinging from each host to the default gateway that has been config-
ured for that host.

From the host PC1, is it possible to ping the default gateway? yes

From the host PC2, is it possible to ping the default gateway? yes

From the host PC3, is it possible to ping the default gateway? yes

If the answer is no for any of these questions, troubleshoot the configurations to find the
error using the following systematic process:

Check the cabling. (Connection could be through a switch or directly.) Are the PCs
physically connected to the correct router? yes

1.

Are link lights blinking on all relevant ports? yes

Check the PC configurations. Do they match the topology diagram? yes 2.

Check the router interfaces using the show ip interface brief command. Are all rele-
vant interfaces up and up? yes

3.

If your answer to all three steps is yes , you should be able to successfully ping the
default gateway.
