Introduction
In this activity, you will configure a Linksys WRT300N, port security on a Cisco switch, and static routes on multiple devices. Make note of the procedures involved in connecting to a wireless network because some changes involve disconnecting clients, which may then have to reconnect after making changes to the configuration.
Task 1: Perform Basic Router Configurations
Step 1. Perform basic router configurations.
Configure R1 according to the following guidelines:
- Router hostname
- Disable DNS lookup
- Configure EXEC mode password of class
- Configure a password of cisco for console connections
- Configure a password of cisco for vty connections
Step 2. Configure router interfaces.
Configure Loopback0, FastEthernet 0/0, 0/1, and any subinterfaces listed in the addressing table. Before configuring the IP addresses on the the subinterfaces, encapsulation must be set to 802.1Q. The VLAN ID is identified by the subinterface number.
Verify the interfaces are up and their IP Addresses are correect with the show ip interfaces brief command.
Task 2: Perform Switch Configurations
Step 1. Perform basic switch configurations.
Configure all three switches according to the following:
- Configure hostnames
- Disable DNS lookup
- Configure EXEC mode password of class
- Configure a password of cisco for console connections
- Configure a password of cisco for vty connections
Step 2. Set VTP mode and create VLANs.
For all switches set the VTP mode to transparent and create the VLANs according to the table at the beginning of this activity.
Verify the creation of the VLANs with the show vlan brief command.
Step 3. Configure switch port interfaces on S1, S2, and S3.
Configure the interfaces on the S1, S2, and S3 switches according to the following:
- Fa0/7 on S2 and S3 are in VLAN 99
- Fa0/5 on S1 is an 802.1Q trunk
- Fa0/11 on S2 is in VLAN 10
- Fa0/18 on S2 is in VLAN 20
- Remaining connected ports are trunk interfaces
- Allow all VLANS across trunking interfaces
Step 4. Verify VLANs and trunking.
Use the show interfaces trunk command on S1 and the show vlan brief command on S2 to verify that the switches are trunking correctly and the proper VLANs exist.
Step 5. Configure the Ethernet interfaces of PC1 and PC2.
Configure the Ethernet interfaces of PC1 and PC2 with the IP addresses and default gateways according to the addressing table at the beginning of the activity.
Step 6. Test the PC configuration.
Access the Command Prompt on each PC and ping its default gateway. The pings should be successful, if not, troubleshoot.
