Ever wondered what it’s like to bring physical IP transit directly to your home over #MPLS? I pulled it off — twice — in India. #BGP, #IXP, fibre runs, barter deals, and plenty of Layer 8 chaos. Blog post up now👇 www.daryllswer.com/how-to-bring... #IPTransit #NetEng #IPTTTH #AS149794

Helped fix a network mess at a non-profit where “certified experts” left behind broken #IPv6, triple #NAT, and the wrong hardware. Might not have been incompetence—might’ve been intentional. Full story + tech details on LinkedIn 👇 www.linkedin.com/posts/daryll... #NetEng #CGNAT #NetworkEngineering

Please read and circulate this explainer from @telegeography.bsky.social that debunks the recent sensationalist headlines stemming from the filing of a Chinese patent for a subsea cable cutter (cut and hold grapnel): blog.telegeography.com/demystifying...

Nice to see that my IPv6 Architecture guide has been helpful enough to inspire ISPs in the USA to adopt BCOP-690—especially with a static /48 prefix delegation for residential customers to boot! #NetworkEngineering #NetEng #IPv6

A couple of years into the telecom/NetEng industry and I'm deploying networks the way I envisioned them, across the globe, from my eBGP-speciality for SP networks on a budget, to intricate and scalable OOB networks to hybrid enterprise networks with intelligent BUM forwarding. …

… Meanwhile, Indian ISPs insists, all of my designs are invalid, while they stick with their next-gen layer 2 stretching across EOL L2-only switches across the nation (yes, a lot of them fear SR/MPLS/EVPN and don't even build simple clos fabrics for their compute infra, let alone fancy VXLAN/EVPN).

I made the right decision to never work with/for Indian organisations, would've never went global if I did. Don't get me started on slave wages when working with Indian ISPs, none of them can afford to pay a monthly gross of $10,000.

I have officially shut down #AS149794’s operations in #BLR. This includes terminating services with #ExtremeIX and my transit provider, deactivating the #BGP session. I’m exploring opportunities to secure physical IP transit from alternative ISPs in the future. #IXP #Routing

Looks like my (free) 10Gbps IP Transit+transport in #BLR, is coming to an end, soon-ish, it's been a fun journey, but all things (free) must come to an end eventually! #BGP #Routing #AS149794 #IPTransit #ASN #MPLS

Yeah I said TCAM in my post but later I referred to it as RAM because nobody knows what TCAM is. Arista's large table solution (algomatch???) uses RAM. You are right most routers *sold* today support tables above 1M but if you look around an Equinix colo you will find that they dont replace stuff.
