some thoughts on add-path and bmp at ripe/ris
by Randy Bush 19 Nov '25

i have some small thoughts on add-path and BMP in RIPE/RIS. this may hinder more than help, unfortunately. as a researcher, of course i would love a wider view into the AS graph and the views of as many ASs as possible. nom nom. but ... add-path, if not done very carefully, and documented in detail for each peer, will produce views i will not understand. it is analogous to not knowing what view a BGP peer gives RIS today. did it give me a full Nth view into peer X? is the path that of a peer, a customer, a provider? and add-path is worse because it prunes in configuration and vendor- dependent and otherwise unpredictable ways. and, as an operator if P is a RIS peer, and they give RIS BMP showing their input from their peers, upstreams, and customers, those peers, upstreams, and customers have not given thir consent to have their internals published! if they want to have RIS publish their internals, they would peer with RIS and choose what view they present. and, of course, the researcher does not know what view, peer, upstream, or customer P's BMP peer is giving them. same problem as above under add-path. randy
