Routing and Switching (CIS-3210) Home Page

This is the home page for Peter Chapin's Routing and Switching course notes for the Fall 2021 semester. Here you will find electronic versions of class handouts, homework assignments, lecture slides, and links to other references of interest. If you are a student taking Routing and Switching consider bookmarking this page.

The course syllabus gives an overview of the course and its content, lists course resources, and describes the grading policy and related issues.
The homework/lab submission area, quizzes, and grade book are on Canvas but all other course resources are here.
The Zoom meeting URL gives you access to the live lectures and the lab sessions. This is Zoom meeting ID: 879 6843 7619, Passcode: 767510.
We will be making use of materials on the Cisco Networking Academy web site. You should be able to log into that site using credentials previously emailed to you. Let me know if you have any problems getting access.
Cisco's PacketTracer tool can be downloaded from the Cisco Networking Academy site. However, as a convenience I'm posting the Windows version of the tool here. A macOS or Linux version is available from the Networking Academy site.
There is an optional text book: CCNAv7: Switching, Routing, and Wireless Essentials; Companion Guide, ISBN=978-0-13-672935-8, Cisco Press
We may also make use of some books in the O'Reilly eBook collection available via Hartness.
I've prepared some general information on submitting assignments.
My home page contains other resources of potential interest.

Cisco Packet Tracer v8.0.1
Cisco IOS Configuration Fundamentals Command Reference
The PDF version of the IOS Command Reference (from 2010) also contains some information about the general behavior of the IOS command processor.
This site provides a nice description of the OSI Seven Layer Model.
Some information on the wiring of Ethernet cables. Generally, straight-through cables will use the 568B standard on both ends, while the crossover cables will have 568A on one end and 568B on the other.
Naming convention for Cisco interfaces.
The Wikipedia page on Router Information Protocol (RIP)
The Wikipedia page on Enhanced Interior Gateway Routing Protocol (EIGRP)
The Wikipedia page on classful network addressing. This method of thinking about IP address is obsolete, being replaced by CIDR (Classless InterDomain Routing). IPv6 has never defined network classes and uses CIDR, in effect, from day one.
RIP for IPv6 from Cisco's website.
If you need to reset your Cisco router back to a default initial state, and you don't remember the passwords needed to log into it, consult this page.
If you need to recover the password of your switch, consult this page.
The VLAN trunking mode cheatsheet gives an overview of the different Cisco VLAN trunking modes and how they interrelate.
RFC-4271 describes BGP: the Border Gateway Protocol. This is (or can be) an exterior gateway protocol used to route between autonomous systems in a wide-area network.
