Paramiko, Netmiko, NAPALM or Nornir?
I had a fantastic chat with David Bombal a while ago in which we covered tons of network automation topics including “should I use Nornir or NAPALM or Netmiko?”
The only answer one can give would be “it depends… on what you’re trying to do” as these three tools solve completely different challenges.
Paramiko is SSH implementation in Python. It’s used by most Python tools that want to use SSH to connect to other hosts (including networking devices).

I have started a new role as a Network Engineer with Valve Corporation. My period of unemployment was short-lived, and I am gainfully employed once more.
No. Don’t ask me about Half-Life 3. I don’t know, and even if I did, I wouldn’t say anything.
Not Another Vendor?
Did I think about going to work for another vendor? Yes, I did. I thought a lot about what I want to do, and what type of company I want to work for. Small/medium/large, vendor/customer, Product Manager vs Engineer, etc.
For now, I decided I want to solve business problems using whichever tools are appropriate, rather than building and selling a single product. I didn’t want to work for a company that just consumes technology though. I want to work somewhere that has interesting problems, and will do whatever is needed to solve those problems - build/buy/cobble together.
Why Valve?
Valve is big enough to offer the right level of challenge, but also small enough that I can make a difference. I’m not lost in the machine, but I am working on a global network.
Valve is also quite a different company. Check out the Employee Handbook to get a sense of Continue reading

Why is Securing BGP just so Damn Hard?
Stories of BGP routing mishaps span the entire thirty-year period that we’ve been using BGP to glue the Internet together. We’ve experienced all kinds of route leaks from a few routes to a few thousand or more. We’ve seen route hijacks that pass by essentially unnoticed, and we’ve seen others that get quoted for the ensuing decade or longer! After some 30 years of running BGP it would be good to believe that we’ve learned from this rich set of accumulated experience, and we now understand how to manage the operation of BGP to keep it secure, stable and accurate. But no. That's is not where we are today. Why is the task to secure this protocol just so hard?AT&T, Sprint, and Cisco Execs Throw Cold Water on 5G

EVPN-PIM: BUM optimization using PIM-SM
Does “PIM” make you break out into hives? Toss and turn at night?! You are not alone. While PIM can present some interesting troubleshooting challenges, it serves a specific and simple purpose of optimizing flooding in an EVPN underlay.
The right network design choices can eliminate some of the elements of complexity inherent to PIM while retaining efficiency. We will explore PIM-EVPN and its deployment choices in this two part blog.
Why use multicast VxLAN tunnels?
Head-end-replication
Overlay BUM (broadcast, unknown-unicast and intra-subnet unknown-multicast) traffic is vxlan-encapsulated and flooded to all VTEPs participating in an L2-VNI. One mechanism currently available for this is ingress-replication or HREP (head-end-replication).
In this mechanism BUM traffic from a local server (say H11 on rack-1 in the sample network) is replicated as many times as the number of remote VTEPs, by the origination VTEP L11. It is then encapsulated with individual tunnel header DIPs L21, L31 and sent over the underlay.
The number of copies created by the ingress VTEP increases proportionately with the number of VTEPs associated with a L2-VNI and this can quickly become a scale problem. Consider a POD with a 100 VTEPs; here the originating VTEP would need to create 99 Continue reading
