Guidelines

For this assignment, the network will look like this.  The routers are Cisco 2911 models and the switches are Cisco 2960 models.

(Todd, 2016)

There will be no need to create any connections or devices for this assignment.

1. Login to the C router and configure the Outside address as 2001:db8:3c4d:1::/64by typing the following commands:  
   1. Ipv6 unicast-routing
   2. Int gi0/0
   3. Ipv6 address 2001:db8:3c4d:1::1/64
2. Now, the inside address needs to be 2001:db8:3c4d:2::/64. Complete this by typing the following commands:  
   1. Int gi0/1
   2. Ipv6 address 2001:db8:3c4d:2::1/64
   3. CTRL+Z
3. Verify by typing the following command:
   1. Show ipv6 route

Capture the screen (screenshot 1) and place it with the related question below.  

4. Continue by typing the following command:
   1. show ipv6 int brief

Capture the screen (screenshot 2) and place it with the related question below.  

5. Login to router A and set it to autoconfig ipv6 by typing the following commandsin Global Configuration mode:  
   1. ipv6 unicast-routing
   2. int gi0/0
   3. ipv6 address autoconfig
   4. No shut
   5. CTRL+Z
6. Confirm by typing the following command:  
   1. sh ipv6 int brief

Capture the screen (screenshot 3) and place it with the related question below.  

Before continuing, answer question 1 below.  

7. Complete this for router B, D, and E.  

Capture the screen (screenshot 4, 5 and 6) for each router and place them with the related questions below.  

8. Setup static and default routing.  On router A configure a static route to the 2001:db8:3c4d:2::/64 by typing the following commands:
   1. config t
   2. ipv6 route 2001:db8:3c4d:2::/64 gi0/0
   3. do show running-config

Capture the screen (screenshot 7) and place it with the related question below.

9. Continue by typing the following command:  
   1. show ipv6 route

Capture the screen (screenshot 8) and place it with the related question below.  

Before continuing, answer question 2 below.

10. On router B, configure a default route by typing the following commands:   
    1. conf t
    2. ipv6 route ::/0 gi0/0
       1. (there is a space after route)
    3. do show running-config

Capture the screen (screenshot 9) and place it with the related question below.  

11. Continue by typing the following command on Router B:  
    1. show ipv6 route

Capture the screen (screenshot 10) and place it with the related question below.  

Before continuing, answer questions 3 and 4 below.  

12. On router D, create a static route the other way by typing the following commands in Global Configuration mode:  
    1. ipv6 route 2001:db8:3c4d:1::/64 gi0/0
    2. do show running-config

Capture the screen (screenshot 11) and place it with the related question below.  

13. Continue by typing the following command:  
    1. show ipv6 route

Capture the screen (screenshot 12) and place it with the related question below.  

14. On router E, do the same.

Before continuing, answer question 5 below.  

15. On Router E, run the following command:
    1. show running-config

Capture the screen (screenshot 13) and place it with the related question below.  

16. Continue by typing the following command:  
    1. show ipv6 route

Capture the screen (screenshot 14) and place it with the related question below.  

17. Ping from router D to router A. First, we need to find out what autoconfig address exists on router A (should being with 2001). Type the following command:
    1. sh ipv6 int brief
18. On router D
    1. Ping <IP ADDRESS>

Capture the screen (screenshot 15) and place it with the related question below.  

Before continuing, answer question 6 below.  

Note: Now, it’s time to practice with OSPFv3. Unfortunately, because OSPF has automagic routing, the routing that was set before needs to be removed. Of course, one could just close the app and re-open it, but practice instead.  

19. On router A type the following command:
    1. no ipv6 route 2001:db8:3c4d:2::/64 gi0/0
20. On router B type the following command:
    1. no ipv6 route ::/0 gi0/0
21. On router D type the following command:
    1. no ipv6 route 2001:db8:3c4d:1::/64 gi0/0
22. On router E type the following command:
    1. no ipv6 route 2001:db8:3c4d:1::/64 gi0/0
23. We aren’t doing this for router C.

Before continuing, answer question 7 below.  

24. IRL, if IPv4 is not configured, RIDs need to be created for each router. On router A, define ospf 1 with RID 1.1.1.1 by typing the following commands:  
    1. ipv6 router ospf 1
    2. router-id 1.1.1.1
25. Now, assign ospf 1 to the outside interface by typing the following commands:
    1. int gi0/0
    2. ipv6 ospf 1 area 0
    3. CTRL+Z
26. Verify by typing the following commands:  
    1. sh ipv6 route
    2. sh ipv6 route ospf
    3. sh ipv6 int gi0/0
    4. sh ipv6 neighbor
27. On router B, define ospf1 with RID 2.2.2.2, then assign OSPF 1 to f0/0 by typing the following commands:  
    1. ipv6 router ospf 1
    2. router-id 2.2.2.2
    3. int gi0/0
    4. ipv6 ospf 1 area 0
    5. CTRL+Z
28. Verify by typing the following commands:  
    1. sh ipv6 route
    2. sh ipv6 route ospf
    3. sh ipv6 int gi0/0
    4. sh ipv6 neighbor
29. Complete the same with routers C, D, & E, changing the “Router-id #.#.#.#” to be 3.3.3.3, 4.4.4.4, & 5.5.5.5, respectively.  On Router C, make sure that you issue the ipv6 ospf 1 area 0on both interfaces (gi0/0 & gi0/1).

Before continuing, answer question 8 below.  

30. In order to confirm the ping, determine the ipv6 addresses for each router. These should all begin with 2001.  Do not use the FE80addresses as they are link-local addresses.  

Finish this assignment by completing question 9 below.

Answer 1

I hope you will take the screenshot simply while following the steps of the assignment on cisco software.

Now, On to the question.

a) What does no shut do?

No shut command simply enables the interface. As mentioned it makes the interface operational.

shut down = "non-operational"
no shut down = "operational".

some devices have their ports shut down by default (such as cisco switch vlan1)
and others have their port no shut down by default.

b) Why are we creating a static route here? Why not a dynamic route?

We are creating a static route in this assignment as we are using a manually-configured routing entry, rather than information from a dynamic routing. Static routing will cause very little load on the CPU of the router and is producing no traffic to other routers. Even it's easy to configure static routing on smaller networks. Here, it is giving the administrator full control over the network behavior because of static routing. It is providing some default routes leaving unnecessary routes.

c) In this context, what is the difference between static and default routes?

All routers are configured to send all packets towards a single router are following the default route which is just a special static route. as in this context, you can clearly see the configurations done with router B shows the example ipv6 route ::/0 gi0/0. Default routes are helpful once handling a network with one exit purpose. It is additionally helpful once a bulk of destination networks got to be routed to one next-hop device.
