Routing protocols and concepts summary ~ BSCI

Found this helpful quick reference guide (BSCI summary at A Networker Blog) for routing protocols and concepts.

Topics covered:

• Routing protocols description and comparison (RIP, IGRP, EIGRP, OSPF, IS-IS, BGP)
• IP addressing scheme (Subnetting, VLSM, CIDR, Route Summarization, etc.)

Although this summary is made for a CCNP-level reader, I’m using it only as a quick reference guide for routing protocols – primarily for RIP, EIGRP and single area OSPF. As you may know, those routing protocols are covered in the CCNA curriculum.  At the moment I’m preparing for my CCNA exam so this summary will be very handy. Wish me luck – I’m taking the exam at the end of this month.

Many improvements and features are available:

• Linux version (Ubuntu, Fedora)
• open development API for Flash Action Script and C++  (according to Jozjan’s post)
• multiuser functionality (group and individual labs, homework, competitions, collaborative construction of virtual networks over a real network)
• additional protocol support: SSH, IPv6, ICMPv6, multi-area OSPF, route redistribution.
• Interface range command is available
• improved support for Frame Relay
• multilayer switch is available (3560)

Annoying sound effects are still turned on by default when you open PT for the first time, but luckily it can be disabled .

Cheat sheets ~ Packetlife.net

Lately I’ve been preparing for my CCNA certificate test and today I’ve found a great study resource – quick reference guides or cheat sheets for protocols (e.g. OSPF, EIGRP, IPv6, Spanning Tree Protocol, etc.), technologies (MPLS, VLANs, etc.), reference (e.g. subnetting, common ports) and everything else like Cisco IOS versions and physical cable terminations.

Cheat sheets are available in PDF format.

You can access them here: http://www.packetlife.net/cheatsheets/.

Here’s a preview for Cisco IOS versions cheat sheet:
