Nick, I appreciate the explanation and example, and agree with that as a very strong recommendation. Reading Noction's IRP Lite documentation (https://www.noction.com/wp-content/uploads/2016/09/irp-lite-documentation.pdf) - page 214, with bgpd.as_pathset to "5 4 2 3" by default (table below),

Tom, The automotive industry has normalized "synthetic". It's motor oil that is artificially created, vs pulled out of the ground and refined. It's a perfect analogy for routes that were created by third-party software, vs organically created/redistributed from the proper AS. Ryan Hamel

The reason high voltage and low voltage aren’t permitted to share a conduit is safety. Chafing/rub outs that would energize low voltage cable and devices with high voltage aren’t protected against in the same way that a high voltage to high voltage short would be. It’s a low likelihood/high c
