2026–W19 #
A little split between this week and last, but I've spent a lot of time with BIRD and debugging a network issue.
Looking Glasses are amazing! Colocataires does not have one, so now we're part of HE's Super Looking Glass and the LG-as-a-Service that bgp.tools has -- to use either you basically just peer with one of their route collectors (either via multi-hop BGP or via a convenient presence at an IXP we are already at) -- then they parse your full routing table and add that to their global view of who can talk to who (and who peers with who).
None of this strictly mattered: an issue that I thought might be related to IRR/ROA filters etc. looks like it's actually L2/L3 issues to do with resolving IPv6 addresses (Neighbour Discovery, the v6 equivalent of ARP resolution).
We're talking about changing the basement around and I might move or lose my homelab space. Really the only things that need to be down there are the switch, router and media-convertor. Apart from the switch they are all pretty small. Maybe I should sell another switch and get an even smaller PoE+ one? I got this one because it has 10G ports and PoE+ (a rare combination) but I no longer need the 10G ports and it is loud as hell.
