Hi,
I have a question regarding what's the most common practice [1]
for transit ASs to filter prefixes from their BGP customers
when using IRR data. (which of course everyone does...)
Would many/most/all/none :
a) accept only the prefixes listed in route objects
or
b) accept these and anything "upto /24" (or "le 24")
I was hoping / assuming the latter but I start getting a different impression.
Yep, and apart from the current status, the tendency would be of interest.
Thanks,
Frank
