PC3 NIC 172.16.4.10 255.255.255.0 172.16.4.1

Verify IP addressing and interfaces. Step 2.

Use the show ip interface brief command to verify that the IP addressing is correct and
that the interfaces are active.

When you have finished, be sure to save the running configuration to the NVRAM of the
router.

Configure Ethernet interfaces of PC1, PC2, and PC3. Step 3.

Configure the Ethernet interfaces of PC1, PC2, and PC3 with the IP addresses and default
gateways from Table 8-5.

Test the PC configuration by pinging the default gateway from the PC.

Step 4.

Task 4: Configure RIP

Configure RIP version 1 routing on each of the routers. Include network statements for each of the
directly connected networks.

Task 5: Observe Routes Being Deleted and Added to the Routing Table

View the routing table on the R1 router.

Step 1.

What networks are shown in the routing table?

172.16.0.0/24 (Level 1 Parent Route)

172.16.1.0 (Child Route)

172.16.2.0 (Child Route)

172.16.3.0 (Child Route)

192.168.1.0/24 (Level 1 Ultimate Route)

Use the debug ip routing command to observe changes in the routing table as they occur
on the R1 router.

Step 2.
