There's another way to fix iBGP scaling besides route reflectors. Almost nobody talks about it at work. BGP Confederations. Sub-ASes. eBGP-like sessions inside your own AS. New video: youtu.be/sXg_DftPyoY #BGP #NetworkEngineering #BourbonAndBGP #Cisco #CCIE #CCNA #CCNP

Confederations split one AS into sub-ASes. From outside you're still one AS. Inside, sub-ASes use eBGP-like sessions. Full mesh stops being your problem. bit.ly/4q2iNv4 #BGP #NetworkEngineering #BourbonAndBGP #Cisco #CCNA #CCNP #CCIE #Networking

BGP session is up. Routes are in the table. Traffic is dead. The next-hop points somewhere your internal routers can't reach. next-hop-self fixes it. bit.ly/4wj454z#BGP #NetworkEngineering #BourbonAndBGP #Cisco #Juniper #Arista #Cisco #CCNA #CCNP #CCIE #Routing

iBGP session is up. Routes are showing up. Traffic fails after one hop and you have no idea why. The next-hop isn't self. That's why. New video: youtu.be/j5OHltZFLTI #BGP #NetworkEngineering #BourbonAndBGP #Networking #Juniper #Arista #Cisco #CCNA #CCNP #CCIE #Routing

iBGP requires a full mesh. 50 routers means 1,225 sessions. Route reflectors fix this. One router re-advertises to the rest. bit.ly/4xlqZJw #BGP #NetworkEngineering #BourbonAndBGP #Cisco #CCNA #CCNP #CCIE #Routing

There's a gap between understanding BGP and actually getting it running. You'll find it the first time a neighbor won't come up and you don't know why. New video: youtu.be/c_chTBsvhoA #BGP #NetworkEngineering #BourbonAndBGP #Networking #Cisco #CCNA #CCNP #CCIE

Reading about BGP and actually configuring it are different skills. You'll figure that out the moment you stare at a neighbor that won't come up and have no idea why. Cisco, Juniper, Arista configs inside. bit.ly/4bAVDpP #BGP #NetworkEngineering #BourbonAndBGP #Networking #Cisco #CCIE #CCNA #CCNP

You know what BGP does. Now someone's asking if your network actually needs it. Short list of things that force the answer to yes. You might not be on it. bit.ly/4wdQ1dn #BGP #NetworkEngineering #BourbonAndBGP #Networking #Cisco #CCNA #CCNP #CCIE

BGP runs a 13-step algorithm every time it picks a path. Most people only know the first four. The other nine are why your traffic does unexpected things at 2am. New video: youtu.be/8mCSOFAtxM8 #BGP #NetworkEngineering #BourbonAndBGP #Networking #CCIE #CCNA #CCNP #Cisco

Everyone memorizes BGP best path for a cert then forgets it immediately. Don't. This is the algorithm that decides where your traffic actually goes. 13 steps, in order. bit.ly/4wkEZmJ #BGP #NetworkEngineering #BourbonAndBGP #Networking #Cisco #CCNA #CCNP #CCIE

BGP doesn't care about your hostname or your IP. It cares about your ASN. Public, private, 2-byte, 4-byte. There's more to this than you think. New video: youtu.be/lf6yBxVsVgA #BGP #NetworkEngineering #BourbonAndBGP #Networking #Cisco #CCNA #CCNP #CCIE #BourbonAndBGP

BGP doesn't care about your hostname. It cares about your ASN. Public, private, 2-byte, 4-byte. There are more types than most people realize until they actually need one. bit.ly/4fhmKbO #BGP #NetworkEngineering #BourbonAndBGP #Networking

10 iBGP routers = 45 sessions. 50 routers = 1,225 sessions. All of it by hand. This is why iBGP doesn't scale and why route reflectors exist. bit.ly/4pAwCAH #BGP #NetworkEngineering #NetworkArchitecture #NetworkEngineer #Cisco #CCNA #CCNP #CCIE #Networking

eBGP and iBGP look the same from the CLI. Same commands, almost identical config. The rules are completely different. Miss the wrong one and you'll be staring at a broken session for an hour. New video: youtu.be/rsQD42d_B2o #BGP #Networking #NetworkEngineering #NetworkArchitecture #Cisco

The sessions look identical. The commands are almost the same. Get the TTL, next-hop, or split horizon rule wrong and you'll wreck something. eBGP vs iBGP. New post. bit.ly/44ICluY #BGP #NetworkEngineering #NetworkArchitecture #NetworkEngineer #Cisco #CCNA #CCNP #CCIE #Networking

BGP runs the internet. Your ISP uses it. Every packet you send touches it at some point. Nobody taught you this. That changes. New video: youtu.be/HJCqZ0Cg6oM #BGP #NetworkEngineering #NetworkArchitect #BourbonAndBGP #Networking

Someone mentioned BGP in your next design review. Before you touch a single neighbor statement, figure out if you actually need it. Most networks don't. Seriously. bit.ly/4wlEKrw #BGP #NetworkEngineering #NetworkArchitect #Networking

BGP's been running the internet since 1994. Your ISP runs it. Your data center runs it. Someone told you it was a service provider protocol. Wrong. bit.ly/4pCGvhC #BGP #NetworkEngineering #Cisco #Networking

OSPF rarely breaks randomly. It exposes MTU mismatches, bad links, or forgotten configs. Here’s a real-world guide to troubleshooting OSPF like an architect — practical, no slides. bit.ly/3OUNcgk #networking #OSPF #neteng #routing

OSPF Troubleshooting Guide: Fix Neighbor + Routing Issues Fast

A practical OSPF troubleshooting guide covering broken adjacencies, missing routes, and the fastest ways to diagnose issues.

OSPF gets a lot simpler after your first real outage. Design lessons from the field: protect Area 0, summarize early, respect redistribution. Built from scars, not theory. bit.ly/4cGMw8d #OSPF #NetEng #Networking #Routing

OSPF isn’t magic. It’s math, structure, and one very honest algorithm. If you’ve ever wondered how routes are actually chosen, this dives into the SPF algorithm in plain English. Clear, practical, architect-level. bit.ly/3OrI0R1 #OSPF #Networking #Routing #NetworkEngineering #NetArch

LSAs are the part of OSPF everyone pretends to understand. Type 1–7. Flooding. NSSA weirdness. Real-world failure modes. If you design networks, you need this. No fluff. Just clarity. bit.ly/4rmrW1z #OSPF #Networking #NetworkEngineering #Routing

Most engineers memorize OSPF areas. Few understand why they exist. Areas aren’t about hierarchy — they’re about containing chaos, limiting SPF blast radius, and keeping your core alive when things flap. bit.ly/3MjJDjb #OSPF #NetworkEngineering #Routing #NetArch #CCNP #CCIE

OSPF has a reputation for being complex, but most of that comes from learning it backwards. This post is a practical intro to what OSPF actually is, how it works, and why architects still trust it in real networks. bit.ly/3ZGll5R #networking #OSPF #NetEng #Routing #NetworkEngineering

OSPF neighbor formation isn’t just a diagram — it’s a journey. From the first Hello to Full adjacency, and the real-world lessons in between. bit.ly/4687c5g #Networking #OSPF #NetEng

I had the pleasure of being on the @thebeardeditdad.com 's podcast to discuss soft skills and why they matter. It is often overlooked that technical chops is one thing but soft skills matter more than people think. Once I realized this it paid dividends. youtu.be/Axn7zsR1qFI?...
