We had the usual gloomy December weather during the end-of-year holidays, and together with the partial lockdown (with confusing ever-changing rules only someone in Balkans could dream up) it managed to put me in OCD mood… and so I decided to remove broken links from the old blog posts.

While doing that I figured out how fragile our industry is – I encountered a graveyard of ideas and products that would make Google proud. Some of those blog posts were removed, I left others intact because they still have some technical merits, and I made sure to write sarcastic update notices on product-focused ones. Consider those comments Easter eggs… now go and find them ;))

Anyway, I also salvaged some of the old content I was stupid enough to publish somewhere else from archive.org. Here it is:

• Disable Flapping BGP Neighbors
• VRF Routing Process Limitations
• SPF Events in OSPF and IS-IS
• PE-to-PE Troubleshooting in MPLS VPN Networks
• Unequal-Bandwidth EBGP Load Balancing
• Load Balancing with Parallel EBGP Sessions
• Using EIGRP in MPLS VPN Networks
• Conditional BGP Route Origination
• Using IP Prefixes, AS Numbers and Domain Names in Examples
• Multihomed IP Hosts
• RIBs and FIBs (aka IP Routing Table and CEF Table)
• IS-IS Is Not Running over CLNP
• Multi-Level IS-IS in a Single Area? Think Again!
