• Using iDRAC with a gen 11 Dell Server (on a Mac) - phew

    This post is really a persistent note for me. Every now and then I end up going down the road where I need to administer a Dell server (typically one I can afford for home use, like a Dell R610) - only to find that everything I rely on at work (like having windows/java/etc) is out the door. Here are some steps to allow access to the iDRAC on Dell Rx10 server from a Mac, using Chrome as a browser.

  • Juniper VMX Trial and Error

    I have spent some time scratching my head on ESXi-based VMX and I thought I would share some experience. This isn’t meant to be a guide, or replace Juniper’s own docs, but to supplement (and help me remember stuff 2 years later).

  • Step by step guide: Preparing a Debian VM for Junos Automation

    This is a bit specific, and, like most of my posts - a cheap way for me to remember something next time I need to do it.

    I am currently obsessed with network automation. My favourite ‘stack’ at the moment is Ansible, git and the Juniper Ansible libraries. There are a thousand ways to skin this particular cat, but for my current project (enforcing ‘golden config’ across a large number of devices) - this limited number of tools does the job.

    As with most cool new tech, there are hundreds of posts and docs, most of which are similar enough to give the illusion of cohesion, but all critically different when it comes to the nitty-gritty, causing confusion and angst. At least, that’s my impression.

    So - if you want a Junos Automation machine, ready to attack your network with Python and Ansible, follow along.

  • Juniper to Fortinet ISIS configuration

    Hoo boy. I have been trying to configure a small mesh network for a fault-resilient office setup. In my network, I have a ‘square’ setup, two VMX routers, two Fortigate virtual firewall appliances, all running on top of ESXi 6.5 (two physical hypervisors). It looks like this:

  • Quick recipe for Layer2 Circuit local switching

    I am always forgetting how to do l2circuits in Juniper, partially as there seem to be a zillion ways to configure encapsulation and VLAN handling, all of which seem to commit but seemingly very few seem to work.

    This is a super quick note-to-self which describes how to locally switch (could simply be extended to LDP-signalled l2circuit over an MPLS core though) a point-to-point circuit, one end VLAN tagged and the other end untagged.
