Part 4: Configure and Verify a Default Route Background / Scenario A router uses a routing table to determine where to send packets. The routing table contains a set of routes that describe which gateway or interface the router uses to reach a specified network. Initially, the routing table contains only directly connected networks. To communicate with distant networks, routes must be specified and added to the routing table. In this lab, you will manually configure a static route to a specified distant network based on a next-hop IP address or exit interface. You will also configure a static default route. A default route is a type of static route that specifies a gateway to use when the routing table does not contain a path for the destination network. Note: This lab provides minimal assistance with the actual commands necessary to configure static routing. However, the required commands are provided in Appendix A. Test your knowledge by trying to configure the devices without referring to the appendix. Note: The routers used with CCNA hands-on labs are Cisco 1941 Integrated Services Routers (ISRs) with Cisco IOS Release 15.2(4)M3 (universalk9 image). The switches used are Cisco Catalyst 2960s with Cisco IOS Release 15.0(2) (lanbasek9 image). Other routers, switches, and Cisco IOS versions can be used. Depending on the model and Cisco IOS version, the commands available and output produced might vary from what is shown in the labs. Refer to the Router Interface Summary Table at the end of this lab for the correct interface identifiers. Note: Make sure that the routers and switches have been erased and have no startup configurations. If you are unsure, contact your instructor. Instructor Note: Refer to the Instructor Lab Manual for the procedures to initialize and reload devices. Lab – Configuring IPv4 Static and Default Routes Required Resources • 2 Routers (Cisco 1941 with Cisco IOS Release 15.2(4)M3 universal image or comparable) • 2 Switches (Cisco 2960 with Cisco IOS Release 15.0(2) lanbasek9 image or comparable) • 2 PCs (Windows 7, Vista, or XP with terminal emulation program, such as Tera Term) • Console cables to configure the Cisco IOS devices via the console ports • Ethernet and serial cables as shown in the topology Part 1: Set Up the Topology and Initialize Devices Step 1: Cable the network as shown in the topology. Step 2: Initialize and reload the router and switch. Part 2: Configure Basic Device Settings and Verify Connectivity In Part 2, you will configure basic settings, such as the interface IP addresses, device access, and passwords. You will verify LAN connectivity and identify routes listed in the routing tables for R1 and R3. Step 1: Configure the PC interfaces. Step 2: Configure basic settings on the routers. a. Configure device names, as shown in the Topology and Addressing Table. b. Disable DNS lookup. c. Assign class as the enable password and assign cisco as the console and vty password. d. Save the running configuration to the startup configuration file. Step 3: Configure IP settings on the routers. a. Configure the R1 and R3 interfaces with IP addresses according to the Addressing Table. b. The S0/0/0 connection is the DCE connection and requires the clock rate command. The R3 S0/0/0 configuration is displayed below. Instructor Note: For Cisco 1941 routers, DCE is automatically detected and the clock rate is automatically set to 2000000, and does not need to be configured. R3(config)# interface s0/0/0 R3(config-if)# ip address 10.1.1.2 255.255.255.252 R3(config-if)# clock rate 128000 R3(config-if)# no shutdown Step 4: Verify connectivity of the LANs. a. Test connectivity by pinging from each PC to the default gateway that has been configured for that host. From PC-A, is it possible to ping the default gateway? __________ Yes From PC-C, is it possible to ping the default gateway? __________ Yes b. Test connectivity by pinging between the directly connected routers. From R1, is it possible to ping the S0/0/0 interface of R3? __________ Yes Lab – Configuring IPv4 Static and Default Routes If the answer is no to any of these questions, troubleshoot the configurations and correct the error. c. Test connectivity between devices that are not directly connected. From PC-A, is it possible to ping PC-C? __________ No From PC-A, is it possible to ping Lo0? __________ No From PC-A, is it possible to ping Lo1? __________ No Were these pings successful? Why or why not? ____________________________________________________________________________________ ____________________________________________________________________________________ No, the router does not contain routes to the distant networks. Note: It may be necessary to disable the PC firewall to ping between PCs. Step 5: Gather information. a. Check the status of the interfaces on R1 with the show ip interface brief command.

Lab – Configuring IPv4 Static and Default Routes Part 3: Configure Static Routes In Part 3, you will employ multiple ways to implement static and default routes, you will confirm that the routes have been added to the routing tables of R1 and R3, and you will verify connectivity based on the introduced routes. Note: This lab provides minimal assistance with the actual commands necessary to configure static routing. However, the required commands are provided in Appendix A. Test your knowledge by trying to configure the devices without referring to the appendix. Step 1: Configure a recursive static route. With a recursive static route, the next-hop IP address is specified. Because only the next-hop IP is specified, the router must perform multiple lookups in the routing table before forwarding packets. To configure recursive static routes, use the following syntax: Router(config)# ip route network-address subnet-mask ip-address a. On the R1 router, configure a static route to the 192.168.1.0 network using the IP address of the Serial 0/0/0 interface of R3 as the next-hop address. Write the command you used in the space provided. ____________________________________________________________________________________ R1(config)# ip route 192.168.1.0 255.255.255.0 10.1.1.2 b. View the routing table to verify the new static route entry.

If the recursive static route is correctly configured, the ping arrives at PC-C. PC-C sends a ping reply back to PC-A. However, the ping reply is discarded at R3 because R3 does not have a return route to the 192.168.0.0 network in the routing table. Lab – Configuring IPv4 Static and Default Routes Step 2: Configure a directly connected static route. With a directly connected static route, the exit-interface parameter is specified, which allows the router to resolve a forwarding decision in one lookup. A directly connected static route is typically used with a point-topoint serial interface. To configure directly connected static routes with an exit interface specified, use the following syntax: Router(config)# ip route network-address subnet-mask exit-intf a. On the R3 router, configure a static route to the 192.168.0.0 network using S0/0/0 as the exit interface. Write the command you used in the space provided. ____________________________________________________________________________________ R3(config)# ip route 192.168.0.0 255.255.255.0 s0/0/0 b.

A default route identifies the gateway to which the router sends all IP packets for which it does not have a learned or static route. A default static route is a static route with 0.0.0.0 as the destination IP address and subnet mask. This is commonly referred to as a “quad zero” route. In a default route, either the next-hop IP address or exit interface can be specified. To configure a default static route, use the following syntax: Lab – Configuring IPv4 Static and Default Routes Router(config)# ip route 0.0.0.0 0.0.0.0 {ip-address or exit-intf} a. Configure the R1 router with a default route using the exit interface of S0/0/1.

Lab – Configuring IPv4 Static and Default Routes 2. Is there a benefit to configuring a directly connected static route instead of a recursive static route? _______________________________________________________________________________________ _______________________________________________________________________________________ Configuring a directly attached static route allows the routing table to resolve the exit interface in a single search instead of in two searches as needed for recursive static routes. 3. Why is it important to configure a default route on a router? _______________________________________________________________________________________ A default route prevents the router from dropping packets to unknown destinations.

There is no way to effectively list all the combinations of configurations for each router class. This table includes identifiers for the possible combinations of Ethernet and Serial interfaces in the device. The table does not include any other type of interface, even though a specific router may contain one. An example of this might be an ISDN BRI interface. The string in parenthesis is the legal abbreviation that can be used in Cisco IOS commands to represent the interface.
