Perform basic configuration tasks on a router. Interpret debug IP routing output. Configure and activate Serial and Ethernet interfaces. Test connectivity. Gather information to discover causes for lack of connectivity between devices. Configure a static route using an intermediate address. Configure a static route using an exit interface. Compare a static route with intermediate address to a static route with exit interface. Configure a default static route. Configure a summary static route. Document the network implementation.
Scenario In this lab activity, you will create a network that is similar to the one shown in the Topology Diagram. Begin by cabling the network as shown in the Topology Diagram. You will then perform the initial router configurations required for connectivity. Use the IP addresses that are provided in the Addressing Table to apply an addressing scheme to the network devices. After completing the basic configuration, test connectivity between the devices on the network. First test the connections between directly connected devices, and then test connectivity between devices that are not directly connected.
Static routes must be conferred on the routers for end-to-end communication to take place between the network hosts. You will configure the static routes that are needed to allow communication between the hosts. View the routing table after each static route is added to observe how the routing table has changed. Task 1: Cable, Erase, and Reload the Routers. Step 1: Cable a network that is similar to the one in the Topology Diagram. Step 2: Clear the configuration on each router. Clear the configuration on each of the routers using the erase startup-confining command and then reload the routers.
Answer no if asked to save changes. Task 2: Perform Basic Router Configuration. Note: If you have difficulty with any of the commands in this task, see Lab 1. 5. 1: Cabling a Network and Basic Router Configuration. Step 1: Use global configuration commands. On the routers, enter global configuration mode and configure the basic global configuration commands including: hosannas no IP domain-lookup enable secret Step 2: Configure the console and virtual terminal line passwords on each of the routers. Password login Step 3: Add the logging synchronous command to the console and virtual terminal lines.
This command is very helpful in both lab and production environments and uses the following syntax: Router(Congo-line)#logging synchronous To synchronize unsolicited messages and debug output with solicited Cisco ISO footwear output and prompts for a specific console port line, auxiliary port line, or virtual terminal line, we can use the logging synchronous line configuration command. In other words, the logging synchronous command prevents ISO messages delivered to the console or Telnet lines from interrupting your keyboard input.
For example, you may have already experienced something similar to the following example: Note: Do not configure RI interfaces yet. RI fasteners 0/0 address 172. 16. 3. 1 255. 255. 255. 0 RI shutdown *Mar 1 %Link-3-UPTOWN: Interface Fastener’s/O, changed state to p *Mar 1 %Lentos-5-UPTOWN: Line protocol on Interface Fastener’s/O, changed state to option RI (Congo-if)# The ISO sends unsolicited messages to the console when you activate an interface with the no shutdown command.
However, the next command you enter (in this case, description) is interrupted by these messages. The logging synchronous command solves this problem by copying the command entered up to that point down to the next router prompt.
