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

25 Sep '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

Planned maintenance to data.ris.ripe.net, ftp.ripe.net, data-store.ripe.net on 25 July, 11:00-15:00 UTC

Dear colleagues, The webserver that distributes RIS files, data.ris.ripe.net, as well as ftp.ripe.net and data-store.ripe.net, will be down for maintenance on 25 July. During the maintenance, a storage appliance will be moved to a different data centre. This is part of the RIPE NCC’s effort to reduce our data centre footprint and increase the geographical distance between our data centres. BGP sessions with RIS collectors will be established as usual, and no data will be lost. However, downloads from https://data.ris.ripe.net will not be available. Other RIS services are not affected. Start: Friday July 25, 2025 11:00 UTC End: Friday July 25, 2025 15:00 UTC Affected: * data.ris.ripe.net * ftp.ripe.net * data-store.ripe.net We expect service to be unavailable for two hours in this window. Kind regards, Ties de Kock RIPE NCC
