Task 3: Prepare the Network
Cable a network that is similar to the topology diagram in Figure 7-4.
Step 1.
You can use any current router in your lab as long as it has the required interfaces as
shown in the topology.
Note:
If you use 1700, 2500, or 2600 routers, the router outputs and interface descriptions will appear different.
Clear any existing configurations on the routers.
Step 2.
Task 4: Perform Basic Router Configurations
Perform basic configuration of the BRANCH, HQ, and ISP routers according to the following guide-
lines:
Configure the router host name.
1.
Disable Domain Name System (DNS) lookup.
2.
Configure an EXEC mode password.
3.
Configure a message-of-the-day banner.
4.
Configure a password for console connections.
5.
Configure a password for VTY connections.
6.
Synchronize unsolicited messages and debug output with solicited output and prompts for the
console and virtual terminal lines.
7.
Configure an EXEC timeout of 15 minutes.
8.
Task 5: Configure and Activate Serial and Ethernet
Addresses
Configure the BRANCH, HQ, and ISP routers.
Step 1.
Configure the interfaces on BRANCH, HQ, and ISP with the IP addresses from the
addressing table provided under the topology diagram.
When you have finished, be sure to save the running configuration to the NVRAM of the
router.
Configure the Ethernet interfaces of PC1, PC2, PC3, PC4, and PC5.
Step 2.
Configure these Ethernet interfaces with the IP addresses from the completed Table 7-6.
Task 6: Verify Connectivity to the Next-Hop Device
You should
not
have connectivity between end devices yet. However, you can test connectivity
between two routers and between an end device and its default gateway.
Verify BRANCH connectivity by ensuring that BRANCH can ping across the WAN link
to HQ and that HQ can ping across the WAN link it shares with ISP.
Step 1.
Verify that PC1, PC2, PC3, PC4, and PC5 can ping their respective default gateways.
Step 2.
