This should not be news. IS-IS has competition in the IGP space. BGP has no competition. > > Show me the complaints from the open-source IS-IS implementors who cannot figure out the spec.

FWIW, I know of three other IS-IS open-source implementations: * Holo (Rust): https://github.com/holo-routing/holo * Bio-Routing (Go): https://github.com/bio-routing/bio-rd * freeRtr (Java): https://github.com/mc36/freeRtr >From my perspective, having written the Holo IS-IS implementation (which is still a work in progress), I don't think there's a problem of underspecification. I personally found all RFCs and the ISO standard to be very precise and well written.
