In-Depth Information
Clear any existing configurations on the routers.
Step 2.
Task 2: Perform Basic Router Configurations
Perform basic configuration of the R1, R2, and R3 routers according to the following guidelines:
Configure the router host name.
Disable Domain Name System (DNS) lookup.
Configure a privileged EXEC mode password.
Configure a message-of-the-day banner.
Configure a password for console connections.
Configure a password for VTY connections.
Task 3: Configure and Activate Serial and Ethernet
Addresses
Configure interfaces on R1, R2, and R3.
Step 1.
Configure these interfaces with the IP addresses from Table 11-2.
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 these interfaces with the IP addresses and default gateways from Table 11-2.
Test the PC configuration by pinging the default gateway from the PC.
Step 4.
Task 4: Configure OSPF on the R1 Router
Use the router ospf command in global configuration mode to enable OSPF on the R1
router. Enter a process ID of 1 for the process-ID parameter.
Step 1.
R1(config)# router ospf 1
R1(config-router)#
Configure the network statement for the LAN network.
Step 2.
When you are in the router OSPF configuration submode, configure the LAN network
172.16.1.16/28 to be included in the OSPF updates that are sent out of R1.
The OSPF network command uses a combination of network-address and wildcard-mask
similar to that which can be used by Enhanced Interior Gateway Routing Protocol
(EIGRP). Unlike EIGRP, the wildcard mask in OSPF is required.
