They are fixed, meaning that they do not change dynamically to meet changing network conditions. They are either valid and made available to the routing table or invalid and not made available to the routing table. Static routes have an administrative distance of one by default. However, static and default routes can be configured with an administrator-defined administrative distance. This capability allows the administrator to put the static or default route in reserve, and only make it available to the routing table when routes with lower administrative distances (usually generated by dynamic routing protocols) are no longer valid. Note: In this lab you will configure static, default, and floating default routes for both IPv4 and IPv6 which may not reflect networking best practices. Note : The routers used with CCNA hands-on labs are Cisco 4221 with Cisco IOS XE Release 16.9.4 (universalk9 image). The switches used in the labs are Cisco Catalyst 2960s with Cisco IOS Release 15.2(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 the output produced might vary from what is shown in the labs. Refer to the Router Interface Summary Table at the end of the lab for the correct interface identifiers. Note : Ensure that the routers and switches have been erased and have no startup configurations. If you are unsure contact your instructor. Required Resources  2 Routers (Cisco 4221 with Cisco IOS XE Release 16.9.4 universal image or comparable)  2 Switches (Cisco 2960 with Cisco IOS Release 15.2(2) lanbasek9 image or comparable)  1 PC (Windows with a terminal emulation program, such as Tera Term)  2013 - 2020 Cisco and/or its affiliates.

Lab - Configure IPv4 and IPv6 Static and Default Routes Part 2: Configure and verify IPv4 and IPv6 addressing on R1 and R2 In Part 2, you will configure and verify the IPv4 and IPv6 addresses on R1 and R2. Use the table above for the information necessary to complete this part. Step 1: Configure IP addresses for both routers. Open configuration window a. Enable IPv6 Unicast Routing on both routers. b. Configure the IP address for all the interfaces according to the Addressing Table. Step 2: Verify addressing a. Issue the command to verify IPv4 assignments to the interfaces. b. Issue the command to verify IPv6 assignments to the interfaces. Step 3: Save your configuration Save the running configuration to the startup configuration file on both routers. Take a screenshot of your active window (press Alt-PrtScn or similar) and insert it here. Close configuration window Part 3: Configure and verify static and default routing for IPv4 on R1 and R2 In Part 3, you will configure static and default routing on R1 and R2 to enable full connectivity between the routers using IPv4. Once again, the static routing being used here is not meant to represent best practice, but to assess your ability to complete the required configurations. Step 1: On R1, configure a static route to R2’s Loopback1 network, using R2’s G0/0/1 address as the next hop. open configuration window a. Use the ping command to ensure that R2’s G0/0/1 interface is reachable. b. Configure a static route for R2’s Loopback1 network via R2’s G0/0/1 address. Step 2: On R1, configure a static default route via R2’s G0/0/0 address. a. Use the ping command to ensure that R2’s G0/0/0 interface is reachable. b. Configure a static default route via R2’s G0/0/0 address. Step 3: On R1, configure a floating static default route via R2’s G0/0/1 address. Configure a floating static default route with an AD of 80 via R2’s G0/0/1 address. Step 4: On R2, configure a static default route via R1’s G0/0/0 address a. Use the ping command to ensure that R1’s G0/0/0 interface is reachable. b. Configure a static default route via R1’s G0/0/0 address. Step 5: Verify that the routes are operational. a. Use the show ip route command to ensure that R1’s routing table shows the static and default routes. b. On R1, issue the command traceroute 10.2.0.1 . The output should show that the next hop is 192.168.1.2.  2013 - 2020 Cisco and/or its affiliates. All rights reserved. Cisco Public Page 4 of 6 www.netacad.com

Lab - Configure IPv4 and IPv6 Static and Default Routes c. On R1, issue the command traceroute 209.165.200.193 . The output should show that the next hop is 172.16.1.2. d. Issue the shutdown command on R1 G0/0/0. e. Demonstrate that the floating static route is working. First, issue the show ip route static command. You should see two static routes. A default static route with an AD of 80 and a static route to the 10.2.0.0/24 network with an AD of 1. f. Demonstrate the floating static route is working by issuing the traceroute 209.165.200.193 command. The traceroute will show the next hop as 192.168.1.2. g. Issue the no shutdown command on R1 G0/0/0. Take a screenshot of your active window (press Alt-PrtScn or similar) and insert it here. Close configuration window Part 4: Configure and verify static and default routing for IPv6 on R1 and R2 In Part 4, you will configure static and default routing on R1 and R2 to enable full connectivity between the routers using IPv6. Once again, the static routing being used here is not meant to represent best practice, but to assess your ability to complete the required configurations. Step 1: On R2, configure a static route to R1’s Loopback1 network, using R1’s G0/0/1 address as the next hop. Open configuration window a. Use the ping command to ensure that R1’s G0/0/1 interface is reachable. b. Configure a static route for R1’s Loopback1 network via R1’s G0/0/1 address. Step 2: On R2, configure a static default route via R1’s G0/0/0 address. a. Use the ping command to ensure that R1’s G0/0/0 interface is reachable. b. Configure a static default route via R1’s G0/0/0 address. Step 3: On R2, configure a floating static default route via R1’s G0/0/1 address. Configure a floating static default route with an AD of 80 via R1’s G0/0/1 address. Step 4: On R1, configure a static default route via R1’s G0/0/0 address. a. Use the ping command to ensure that R2’s G0/0/0 interface is reachable. b. Configure a static default route via R2’s G0/0/0 address. Step 5: Verify that the routes are operational. a. Use the show ipv6 route command to ensure that R2’s routing table shows the static and default routes. b. On R2, issue the command traceroute 2001:db8:acad:10::1 . The output should show that the next hop is 2001:db8:acad:1::1. c. On R2, issue the command traceroute 2001:db8:acad:209::1 . The output should show that the next hop is 2001:db8:acad:2::1. d. Issue the shutdown command on R2 G0/0/0. e. Demonstrate the floating static route is working. First issue the show ipv6 route static command. You should see two static routes. A default static route with an AD of 80 and a static route to the 2001:db8:acad:10::/64 network with an AD of 1.  2013 - 2020 Cisco and/or its affiliates. All rights reserved.

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.
