Have there been talks about the best practices to accept things smaller than a /24?
Hi Justin,
The short version is: it could happen but it won't. There's no technical obstacle. It's purely administrative. Tens of thousands of organizations would have to agree to accept smaller prefixes.That would only happen if there was something in it for them to start doing so, something major. And even then it would be a hard lift. There isn't. Some of those organizations run BGP set up by the last guy, the current gut doesn't really grok it, and he certainly doesn't subscribe to any information channels where it's discussed. So it's not going to happen.
The "other problem" is, every day more gear receiving full routes gets closer to (or farther past) the point where the resources to hold either the FIB or RIB just aren't there. For those using these devices, lowering the bar and bringing in another 100k or so routes in short order just isn't an option. /24 has been the de facto threshold for routes in the v4 table long enough that I wouldn't want to be dependent on that changing. ---------------------------------------------------------------------- Jon Lewis, MCP :) | I route StackPath, Sr. Neteng | therefore you are _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
