CCNAv2 Completed Packet Tracer

Hello, and welcome to my blog for CCNA.
Please read all of the text before downloading.
Below you will find completed PT / PDF files:


This packet tracer is a PT for Chapter 6, which is static routing and it's related topics.
Note that "Scenario 1" and "Scenario 2" ("Scenario 3") are all different packet tracers, but have the same setup for us to learn from.

Below are the commands (with a tutorial) if you don't want to download.

Packet Tracer Tutorial: Explanation and Commands
Like our old packet tracer (the previous one to this), we calculated and configured summary routes. Route summarization (aggregation) is the process of advertising contiguous sets of addresses as a single address. Basically, this PT is a giant version of the prior packet tracer. However, unlike the IPV4 alternative to this PT, you will have to configure R1 for loopback interfaces instead of adding a new network (lan) to R1. We can verify it works via previous testing methods.

From the PT's activity file: 
  When summarizing an IPv6 address, look at the prefix to determine where the address ends. In this case, a /64 ends at the fourth segment.
  List the first four segments of each of the networks. Because the first three segments have the identical hexadecimal digits, there is no need to write them in binary. The fourth segment is different (:A, :B, :C, and :D); therefore, write the 16 bits for each in binary. Count the left-most matching bits to determine the prefix for the summary route.




See my notes if you can't calculate, it's somewhere in this blog. Ultimately, you end up with this IPv6 address, if you did not, check your work and try again.

Result of calculating yields this IPv6 Address:
--- 2001:0DB8:5F73:8::/61

Alright, so now that we have that, open up R1. 

Diagnostic / Basic Commands
R1> en
R1# conf t

Configuration Commands
R1(config)# ipv6 route 2001:0DB8:5F73:8::/61 s0/0/0
R1(config)# ex 

As stated in the previous packet tracer, we can use s0/0/0 over IP addresses because R1 (in this PT) is directly connected. The diagram below might help you if you don't understand.

As you can see, R1 has a direct connection so we don't need to configure it with an IP address. (IPV6)

After entering the commands above, you should be completed with the packet tracer.
