Hi, I’m Kharisma Rizki.
I’m a network engineer working in the ISP environment, interested in understanding how networks actually work — from a single Ethernet frame to the routing systems that connect networks together.
This website is where I keep my notes, experiments, projects, and things I don’t want to forget.
// What you’ll find here

Notes about BGP, OSPF, MPLS, Juniper, Huawei, ISP infrastructure, peering, and other networking stuff.
Projects
Things I build for fun, work, or simply because I was curious about how something works.Notes
