Lessons Learned Writing a Custom Config Builder.. By.. stretch.. | Friday, July 26, 2013 at 2:34 p.. m.. UTC.. A while back, I set about developing a modest configuration templating system for my employer.. When I first joined the company, new network devices were being provisioned using configuration templates stored as Microsoft Word files, which, as you can imagine, was pretty painful.. Each variable had to be identified and replaced by hand in a tedious and error-prone process.. I wanted something better, but also cheap (or free) and simple.. So I started building something.. To kick off my crazy project, I first decided to build a web application based on the.. Django Python framework.. (the same platform on which PacketLife.. net runs).. Django and similar frameworks handle most of the mundane tasks involved in writing a web application and allow for rapid prototyping.. It also includes a built-in administration interface for creating and manipulating data independent of the front-end user interface.. I spun up a modest internal VM running.. 17 comments.. Read more.. Route Distinguishers and Route Targets.. | Monday, June 10, 2013 at 2:27 p.. People new to MPLS VPN are often unclear on what functions route distinguishers and route targets serve, and the difference between the two.. Let's see if we can clear up some of that confusion.. If you could use a refresher on VRF fundamentals, I encourage you to first check out my earlier articles on the topic,.. Intro to VRF lite.. and.. Inter-VRF Routing with VRF Lite.. Route Distinguisher.. As you know, VRFs allow IP address space to be reused among isolated routing domains.. For example, assume you have to connect to three customer sites, all of which are using 192.. 168.. 0.. 0/24 as their local network.. We can assign each customer its own VRF so that the overlapping networks are kept isolated from one another in their respective routing domains.. This works well, but we need a way to keep track of which 192.. 0/24 route belongs to which customer.. This is where route distinguishers come in.. As its name implies, a route distinguisher (RD).. distinguishes.. one set of routes (one VRF) from another.. It is a unique number prepended to each route within a VRF to identify it as belonging to that particular VRF or customer.. An RD is carried along with a route via MP-BGP when exchanging VPN routes with other PE routers.. 15 comments.. Network Engineering Stack Exchange Beta Live!.. | Monday, May 20, 2013 at 3:58 p.. A couple months ago, I.. announced a proposal.. to start a.. Stack Exchange.. site dedicated to answering questions concerning network engineering, similar to how.. Stack Overflow.. Server Fault.. cater to the concerns of programmers and systems administrators, respectively.. I'm happy to announce that the proposal has made it through the definition and commitment phases and last week was opened as a public beta site at.. networkengineering.. stackexchange.. com.. ! The beta process is critical for shaping the content and style of the site, so the more people use it the better we can refine and nurture its content.. Why a Stack Exchange site? The platform has proven immensely useful for directed troubleshooting and answering targeted questions.. As opposed to discussion forum threads, which often digress into tangents and off-topic conversation over the course of days or weeks, the streamlined question-and-answer format of the site leverages community feedback and voting to promote what is accepted at the best answer (which the asker can optionally confirm).. This medium is much better suited to questions which can be directly answered (e.. g.. "How can I.. ?" and not "What's the best.. ?"); please keep this in mind if you decide to participate in the beta.. Check out the beta!.. 3 comments.. ERSPAN from NX-OS to IOS.. | Tuesday, May 14, 2013 at 6:27 p.. Most readers are probably familiar with the switchport analysis (SPAN) feature on Cisco's Catalyst switches.. SPAN replicates all ingress and/or egress traffic from one or several interfaces to another for the purposes of packet capture or traffic monitoring.. This is especially helpful when  ...   CLI of a router (the management plane) and configure EIGRP to exchange routing information with neighbors (the control plane), which gets installed into its local CEF table (the forwarding plane).. All of these operations occur within the same device, and each node in the network operates autonomously to make its own forwarding decisions based on its local configuration.. It's critical to recognize that, although this allows for highly dynamic and automatic forwarding decisions through the use of robust protocols, the end result is ultimately dependent on each node's independent configuration.. For the purposes of establishing context, we can think of this as.. administratively-defined networking.. 23 comments.. The Importance of Watching the Wire.. | Wednesday, April 3, 2013 at 1:42 a.. I came across an interesting problem today that I think serves as an excellent example of why packet analysis is such a critical skill for network engineers.. A few days ago, the internal network belonging to one of my employer's customers was compromised by a malicious party.. Since the customer had connectivity into our network by way of a VPN tunnel and we didn't want to knowingly expose ourselves or other customers to the threat, we saw fit to temporarily sever the VPN while the breach was tended to by another party.. We also upgraded the site's core switch to better support a feature useful in the analysis of the breach.. Shortly thereafter, we began receiving reports of problems with Internet connectivity from the site.. Everything was reachable, it was just.. slow.. And worse, the issue seemed not to have any uniform effect: One person experiencing the issue might sit next to someone else who was completely immune and who noticed no difference from the day before.. This of course made troubleshooting frustrating, to say the least.. First we tried reversing the firmware upgrade on the core switch, as it was reasonable to suspect we may have encountered some obscure bug, but this was quickly revealed to be a.. red herring.. as the issue persisted.. On-site engineers verified that they could still reach everything (excluding of course our internal resources which were no longer reachable as a result of severing the VPN) and speed tests showed mostly normal results.. There was no correlation between affected users and any access switch, VLAN, or IP subnet.. We also confirmed about seventeen times that Internet traffic was in fact traveling from end hosts through the firewall directly to the Internet, with no proxy or caching servers in between.. 32 comments..

  • Title: Blog - Packet Life
    Descriptive info: Latest Entries.. Archive.. Suggest a Topic.. Follow the RSS feed.. Suggest a Blog Topic.. Five Years.. | Saturday, March 23, 2013 at 7:53 p.. Today marks the five-year anniversary of my first post on Packet Life.. (Funny, it doesn't feel like it's been that long.. ) Those of you who follow the blog regularly no doubt have noticed that I don't post as often as I used to.. Several factors contribute to this, probably the largest of which has been the increasing burden and tedium of my day job.. My wife and I also relocated here to the Raleigh-Durham area of North Carolina last year, so getting settled has eaten up a good amount of time over the past months.. Rather than rehashing the past year, I thought it would be interesting to discuss what's coming up in the near future.. We've seen quite a number of new technologies and ideas pop up recently, so many in fact that I've been having a difficult time keeping sense of it all.. Here's my take on what will be big in our world over the next few years.. Software-Defined Networking (SDN).. The functions of any network device can be assigned among three planes of operation: control, forwarding, and management.. Traditionally, routers and switches (or switch stacks) have been deployed as autonomous units which operate independently on all three planes.. A router, for example, might be configured via SSH (management plane) to learn routes via OSPF (control plane) which are then installed in its forwarding table (forwarding plane).. Software-defined networking (SDN) is a broad term which refers to offloading the functions of the control and management planes from individual devices to a centralized controller.. Proposing a Stack Exchange Site for Networking.. | Friday, March 15, 2013 at 12:34 a.. If you've spent any time writing code, you've undoubtedly come across.. , a question and answer forum dedicated to the discussion of computer programming which has become quite popular in recent years.. Its popularity led to the formation of the.. network of sites with a similar format focused on various other topics ranging from.. systems administration.. to.. English grammar.. LEGO.. But nothing for us networkers.. What's particularly interesting about Stack Exchange is that anyone can propose a new site.. Poking around, it seems that a networking-oriented site has been suggested at least once in the past but was dismissed as overlapping with the sysadmin-focused Server Fault site (which, with respect to our IT brethren, is simply rubbish).. I think a networking-focused  ...   3:.. Thanks to all your support, the proposal has been accepted and a beta site is in the works! A successful beta trial is the last step in the process of founding a new site, so continued support and involvement is critical.. Update 4:.. After just nine days the site is now in public beta at.. ! Everyone is welcome to join and contribute.. CCIE University.. | Tuesday, February 26, 2013 at 12:30 a.. Just a quick heads up for CCIE candidates: A reader contacted me today to point out yet another company who has ripped off my (free) content and repackaged it as their own.. The offending company is a bootcamp named CCIE University, at ccieuniversity.. They are offering my collection of free cheat sheets, stripped of attribution, to trick people into signing up for their email list.. The collection being offered is the same as the.. cheat sheet ZIP archive.. (but with each file slightly corrupted due its manipulation).. The purpose of this post is not to rant about having my stuff plagiarized again (well, maybe a little), but to serve as a reminder to thoroughly investigate any training providers you're considering doing business with.. There are plenty of reputable CCIE training companies to choose from providing quality materials and instruction worldwide.. Don't cheat yourself by settling for regurgitated content.. I don't know if it's greed or just a complete lack of integrity which drives individuals to such tactics.. I can only wonder from whom they stole the products they actually sell.. WAN Circuit Topologies.. | Wednesday, February 6, 2013 at 4:26 a.. There are a variety of approaches to connecting multiple sites across a wide area network (WAN), ranging from leased lines to MPLS to IPsec VPN tunnels.. Unfortunately, many of the options and potential WAN topologies are often misunderstood or confused with one another.. Point-to-Point.. A point-to-point circuit, as its name implies, connects exactly two points.. This is the simplest type of WAN circuit.. Packets sent from one site are delivered to the other and vice versa.. There is typically some amount of processing and encapsulation performed across the carrier's infrastructure, but it is all transparent to the customer.. A point-to-point circuit is typically delivered as a layer two transport service, which allows the customer to run whatever layer three protocols they want with an arbitrary addressing scheme.. A customer can change or add an IP subnet in use on a layer two circuit without coordinating with their provider.. 12 comments.. More Articles..
