I have been using powerline adapters to connect the bedroom TV, Odroid and IPTV box to my network. It worked fine, quite fast close to 1Gbit speeds, and can pass through VLANs without any problems. That is, until one of the adapters started smelling like burnt plastic one random Sunday afternoon. I’ve decided it’s too much of a fire risk even if they honor the warranty and replace them. In the...

My network AS203528 has eBGP Multihop peering to a couple of route collectors - both from BGP.tools and NLNOG These peerings are off a couple of my routers OSR1GLASS1 and OSR2GLASS1 - in both Ostrava sites, and their only purpose is for these route collection peerings and for the Looking glass (Hyperglass). Being accessible by the Looking glass means they’re very firewalled - to prevent any la...

So this is a short post. I’m studying for the JNCIP-SP and I found very interesting that although l2circuits / Martini PWs need the VLANs at both ends to match, this disappears from the LDP label mapping if there’s outer-vlan-map swap present PE configs fabrizzio@PE01# show interfaces ge-0/0/4.150 encapsulation vlan-ccc; vlan-id 150; fabrizzio@PE01# show protocols l2circuit neighbor 10....

My hobby network (AS203528) keeps growing. I had a full iBGP mesh among those routers, however that’s no longer viable. I already have 4xBGP Route reflectors on my internal network. I want to re-use those same reflectors for AS203528. Those two networks have each their own IGP, and are just peered with each other. The Plan My entire network needs to be able to pass a cold start / bootstrap i...

Today I wanted to play around with VXLAN as I’ve never touched it and I had nothing better to do. This has been tested with the latest VyOS nightly 1.5-rolling-202403050022. First, I read the related VyOS blog post and the FRR docs. I really prefer learning while doing things instead of just reading the theory. Even though it means I will likely mess something up, that’s precisely what the Lab...
