"Why doesn't this PING work!?!" Here is a simple 3 router configuration, well at least it is simple on 2 of the 3 routers. R1 and R3 are configured quite traditionally, but R2 is a bit more involved. Here is the diagram. Here are the details. R2 is using a VRF which includes both LAN interfaces. R2 is also acting as a Zone Based Firewall in transparent mode, allowing all ICMP traffic in both directions, as well as SSH from the inside to the outside networks. R2 has a bridged virtual interface... Read More

RFC, or Request for Comments, are documents published that describe various items surrounding computer networking. Generally, these are memorandums published by the Internet Engineering Task Force. RFCs can be a great resource. For some unknown reason, most candidates preparing for the CCIE don't take the time to review these documents, which can be very helpful in assisting with understanding the how and why of various networking components. Perhaps the language is a bit dry, or they prefer... Read More

You have just been given a shiny, new router to configure.  As part of the configuration, you are asked to configure an outbound access list which will only permit traffic through to specific destinations.  Here are the requirements that you are given for your access-list: Match (and permit) the following destinations using an access-list.  Your access list should use the fewest number of lines, and should not overlap any other address space. Anything within the 10.0.0.0/8 address space.... Read More

The leading question: "Is it possible (and if so, how) to redistribute or originate a default route based on time of day?" The short answer is "Sure, why not?"...  But the longer answer has to do with how do we warp the forces of the universe to make that happen??? Well, start with what we know.  We know we can do time-ranges in access-lists, right?  Can we do them in standard access-lists (what we see used for redistribution all the time)? Rack1R1(config-if)#exit Rack1R1(config)#access-list 1... Read More

Answers for Part II So the answers to the exciting tasks at hand.... There was a good amount of activity surrounding answers submitted for the contest!  It was good to see that many people interested in them!  Now, it's time to go through the answers and stretch the imagination a bit!  Be prepared for some stretching as well! One quick thing to point out before we get started, there was a question asked about why /24 routes won't have a ".255" as the fourth octet.  This really depends on how we... Read More

Thank you to everyone who participated...  It was my first time running a little contest on the blog, and I'm sorry to say it didn't quite work as I expected!  The comments were not supposed to be seen until a day later, but I think I forgot to share that with the other folks here!  My bad!

As CCIE candidates, we are asked to do all sorts of things with access lists.  We have them in lots of different places, and use them in lots of different ways.  So many, sometimes, that it becomes very confusing to follow things! Read More
