Objectives

Part 1: Build the Network and Configure Basic Device Settings

Part 2: Configure and verify IP and IPv6 addressing on R1 and R2

Part 3: Configure and verify static and default routing for IPv4 on R1 and R2

Part 4: Configure and verify static and default routing for IPv6 on R1 and R2

Background / Scenario

Static and Default routing are the simplest forms of network routing and configured manually. 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the routing table when routes with lower administrative distances (usually generated by dynamic routing protocols) are no longer valid.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 Answers.

Answers Note: Refer to the Answers Lab Manual for the procedures to initialize and reload devices

Step 2:Configure basic settings for each router.

1. Assign a device name to the router.

Open configuration window

router(config)# hostname R1

router(config)# hostname R2

2. Disable DNS lookup to prevent the router from attempting to translate incorrectly entered commands as though they were host names.

R1(config)# no ip domain lookup

R2(config)# no ip domain lookup

3. Assign class as the privileged EXEC encrypted password.

R1(config)# enable secret class

R2(config)# enable secret class

4. Assign cisco as the console password and enable login.

R1(config)# line console 0

R1(config-line)# password cisco

R1(config-line)# login

R2(config)# line console 0

R2(config-line)# password cisco

R2(config-line)# login

7. Create a banner that warns anyone accessing the device that unauthorized access is prohibited.

R1(config)# banner motd $ Authorized Users Only! $

R2(config)# banner motd $ Authorized Users Only! $

8. Save the running configuration to the startup configuration file.

R1(config)# exit

R1# copy running-config startup-config

R2(config)# exit

R2# copy running-config startup-config

Close configuration window

Step 3:Configure basic settings for each switch.

Open configuration window

1. Assign a device name to the switch.

switch(config)# hostname S1

switch(config)# hostname S2

2. Disable DNS lookup to prevent the router from attempting to translate incorrectly entered commands as though they were host names.

S1(config)# no ip domain-lookup

S2(config)# no ip domain-lookup

3. Assign class as the privileged EXEC encrypted password.

S1(config)# enable secret class

S2(config)# enable secret class

4. Assign cisco as the console password and enable login.

S1(config)# line console 0

S1(config-line)# password cisco

S1(config-line)# login

S2(config)# line console 0

S2(config-line)# password cisco

S2(config-line)# login

6. Encrypt the plaintext passwords.

S1(config)# service password-encryption

S2(config)# service password-encryption

7. Create a banner that warns anyone accessing the device that unauthorized access is prohibited.

S1(config)# banner motd $ Authorized Users Only! $

S2(config)# banner motd $ Authorized Users Only! $

8. Shutdown all interfaces that will not be used.

S1(config)# interface range f0/1–3, f0/6-24, g0/1-2

S1(config-if-range)# shutdown

S2(config)# interface range f0/1–3, f0/6-24, g0/1-2

S2(config-if-range)# shutdown

9. Save the running configuration to the startup configuration file.

S1(config-if-range)# exit

S1# copy running-config startup-config

S2(config-if-range)# exit

S2# copy running-config startup-config

Question:

Issuing the command show cdp neighbors at this point on R1 or R2 results in an empty list. Explain.

Because the router interfaces are shut down by default.

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

1. Enable IPv6 Unicast Routing on both routers.

R1(config)# ipv6 unicast-routing

R2(config)# ipv6 unicast-routing

2. Configure the IP address for all the interfaces according to the Addressing Table.

R1(config)# interface g0/0/0

R1(config-if)# ip address 172.16.1.1 255.255.255.0

R1(config-if)# ipv6 address fe80::1 link-local

R1(config-if)# ipv6 address 2001:db8:acad:2::1/64

R1(config-if)# no shutdown

Step 3:Save your configuration

Save the running configuration to the startup configuration file on both routers.

R1# copy running-config startup-config

R2# copy running-config startup-config

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

1. Use the ping command to ensure that R2’s G0/0/1 interface is reachable.
2. Configure a static route for R2’s Loopback1 network via R2’s G0/0/1 address.

R1(config)# ip route 10.2.0.0 255.255.255.0 192.168.1.2

Step 2:On R1, configure a static default route via R2’s G0/0/0 address.

1. Use the ping command to ensure that R2’s G0/0/0 interface is reachable.
2. Configure a static default route via R2’s G0/0/0 address.

R1(config)# ip route 0.0.0.0 0.0.0.0 172.16.1.2

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.

R1(config)# ip route 0.0.0.0 0.0.0.0 192.168.1.2 80

Step 4:On R2, configure a static default route via R1’s G0/0/0 address

1. Use the ping command to ensure that R1’s G0/0/0 interface is reachable.
2. Configure a static default route via R1’s G0/0/0 address.

R2(config)# ip route 0.0.0.0 0.0.0.0 172.16.1.1

Step 5:Verify that the routes are operational.

1. Use the show ip route command to ensure that R1’s routing table shows the static and default routes.

R1# show ip route

Codes: L – local, C – connected, S – static, R – RIP, M – mobile, B – BGP

D – EIGRP, EX – EIGRP external, O – OSPF, IA – OSPF inter area

C209.165.200.224/27 is directly connected, Loopback2

L209.165.200.225/32 is directly connected, Loopback2

2. On R1, issue the command traceroute 10.2.0.1. The output should show that the next hop is 192.168.1.2.

R1# traceroute 10.2.0.1

Type escape sequence to abort.

4. Issue the shutdown command on R1 G0/0/0.

R1# config terminal

R1(config)# interface g0/0/0

R1(config-if)# shutdown

R1(config-if)# end

5. 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.

R1# show ip route static

Codes: L – local, C – connected, S – static, R – RIP, M – mobile, B – BGP

7. Issue the no shutdown command on R1 G0/0/0.

R1# config terminal

R1(config)# interface g0/0/0

R1(config-if)# no shutdown

R1(config-if)# end

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

1. Use the ping command to ensure that R1’s G0/0/1 interface is reachable.
2. Configure a static route for R1’s Loopback1 network via R1’s G0/0/1 address.

R2(config)# ipv6 route 2001:db8:acad:10::/64 2001:db8:acad:1::1

Step 2:On R2, configure a static default route via R1’s G0/0/0 address.

1. Use the ping command to ensure that R1’s G0/0/0 interface is reachable.
2. Configure a static default route via R1’s G0/0/0 address.

R2(config)# ipv6 route ::/0 2001:db8:acad:2::1

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 R2’s G0/0/1 address.

R2(config)# ipv6 route ::/0 2001:db8:acad:1::1 80

Step 4:On R1, configure a static default route via R1’s G0/0/0 address.

1. Use the ping command to ensure that R2’s G0/0/0 interface is reachable.
2. Configure a static default route via R2’s G0/0/0 address.

R1(config)# ipv6 route ::/0 2001:db8:acad:2::2

Step 5:Verify that the routes are operational.

Router Interface Summary Table

Note: To find out how the router is configured, look at the interfaces to identify the type of router and how many interfaces the router has. 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.
