Hi Job,
I believe your disclaimer makes a lot of sense. From our perspective using more
specifics is one of the options to make BGP follow the optimized path instead
of the « natural » path. We used to be doing more specifics because with the
same prefix being announced, we were simply not ge

We regularly see poorly configured "optimizers" or networks hijacking our
prefixes (originating /25's, /24 of /23's etc).
Thankfully, most of the time filters are in place to stop them leaking
badly, but I agree, these are toxic.

I would like to use a BGP optimizer, but I'm too poor. :-\
That said, I'm also an eyeball network, so modifications of my own
advertisements are what affects the desired traffic, not so much the outbound
routes. I know the BGP optimization industry is weighted towards content
networks.
