I prefer the approach of disaggregating only when needed, not as a preventative measure. There are tools that can help with automating this disaggregation (ARTEMIS can do this, for example). — Chris On Mon, Aug 9, 2021 at 10:50 AM Billy Croan <BCroan () unrealservers net> wrote:
How does the community feel about using /24 originations in BGP as a tactical advantage against potential bgp hijackers? All of our allocations are larger and those prefixes we announce for clients as well usually are. But we had a request recently to originate everything as distinct /24 prefixes, to reduce the effect of a potential bgp hijack. It seemed a little bit like a tragedy of the commons situation. Is this seen as route table pollution, or a necessary evil in today's world? How many routers out there today would be affected if everyone did this? Are there any big networks that drop or penalize announcements like this?
