Routers vs Switches, When to position which?
Everyone knows the difference between a router and switch right? Good.. (for those that need a good refresher) this post is not going is not going to dive into that topic. What I want to talk about is Router vs Switching from a positioning standpoint. One question I often get asked working with customers is: “Can I […]

Raspberry Pi RSPAN Capture Box
For some time I have had issues while doing captures such as finding the elusive “spare laptop” you can use, multiple trips out to the site to pick up the captures, or finding another NIC to put in there so you can connect remotely and copy the captures over the network, taking up 2 switch […]

HTIRW: IETF Organizational Structure
So far, we’ve looked at the naming system, routing, and policy in our travel through “internet land.” Last time, we took a quick look at some of the various organizations that create the standards that make the internet work. This time I’m going to start looking in more depth at one specific standard body, or […]

Parsing Junos XML with Python
I’ll admit it – I’ve drunk the “Network Engineers should learn programming” Kool-Aid. In so doing, I’m gearing up for Kirk Byers upcoming “Python for Network Engineers” course by hacking a bit of Python most every evening. Kirk has recently released a Python “wrapper” module for the popular Python SSH module “Paramiko” that simplifies connections […]

A Look Ahead to Packet Pushers Content in 2015
Here’s an update on some Packet Pushers news, and a look ahead to the content we’re planning for 2015. No scary announcements, just some thoughts to share. Circling Back Around On Show 200 I think we’ve mentioned it before, but the response we received to show 200 was very encouraging to us. That’s understated. You really blew […]

Using IPv6 to Defeat Multi-tenancy Separation
I’ve always advised my clients to carefully plan the implementation of IPv6. The protocol opens new attack vectors on which ne’er-do-wells can assault your infrastructure. There are countless examples I’ve seen such as service providers locking down access to routers using IPv4 transport but leaving IPv6 transport completely open. About a year ago, I stumbled […]

A Single Architect for Your Network
I finally got around to reading The Mythical Man Month (MMM), a famous book on large-scale software development projects (think operating systems) written in 1975, revised in 1995, and still strikingly relevant today in the neighboring field of building and managing massive networks. While multiple points land directly on those of us working on massive […]

BGPSEC: Replays, Timers, and Performance
Let’s return to our simple four AS network to look at a number of issues with BGPSEC — the bits you won’t often hear discussed in just about any forum. Assume, for a moment, that AS65000 advertises some route, say 192.0.2.0/24, to AS65001, and not to AS65002. For whatever reason, a few days pater, the […]

Show 218 – OSPF Design Part 2
A long time ago, Packet Pushers ran an OSPF Design Part 1 show. That show went after the default design guides that network engineers have been reading for years, making the big point that you can scale a single OSPF area quite large indeed. But…that’s not the entire story about OSPF areas. Areas still have their use cases, […]
