Too large AS-sets
by Antti Ristimäki 19 Oct '21

19 Oct '21

Colleagues, I'd like to hear how you others deal with those peers, whose AS-sets expands to way too large prefix-lists and/or as-paths. There are some networks that only ever add members to their AS-sets, but never remove. I have some deep frustration at (automatically) configuring our routers with prefix-lists or as-path filters that are magnitude or two as big as the specific peer's real advertised route count. Modern router platforms can quite easily handle large configs, but gigantic as-path filters seem to cause unnecessary increase in commit times at least in our JunOS platforms. The penalty feels higher than the reward. After all, if the peer's AS-set expands to cover big portion of the entire ASN space, I'm begin to ponder whether it would make more sense to drop IRR based as-path filtering altogether for those peers and use e.g. some sort of generalized peerlock filter? Are there any others as frustrated as I am and how have you solved this issue? I will appreciate constructive feedback. -Antti

Your opinion on Internet monitoring and measurements - a 10min survey
by Pavlos Sermpezis 18 Oct '21

18 Oct '21

Hi all, Do you use Internet monitoring and measurements (e.g., RIPEstat, RIPE RIS/Atlas, RouteViews, bgp.he.net, etc.) for your operations? What are your use cases? We (researchers) are trying to identify limitations and biases of the Internet monitoring infrastructure, and come up with ideas to fix them. We would like to hear your opinion! Please help us by answering our short anonymous survey; it should take less than 10min. Survey URL: https://forms.gle/9xJpYFw3PBo8KShz9 Thank you in advance, Pavlos Sermpezis PS. You can find more about our research project (funded by RIPE NCC) here https://sermpezis.github.io/ai4netmon/ -- Pavlos Sermpezis Postdoctoral researcher Datalab (https://datalab.csd.auth.gr/) Informatics Dept.

Add BGPsec support to Hosted RPKI?
by Job Snijders 18 Oct '21

18 Oct '21

Dear all, [ TL;DR: What does the working group think about supporting an extension to the RPKI Dashboard to enable publication of BGPsec certs? ] At the moment the hosted "RPKI Dashboard" at https://my.ripe.net/#/rpki, only permits Resource Holders to create RPKI objects of one specific type: ROAs. However, a wider range of RPKI cryptographic product types also exists, for example: BGPsec Router Certificates [RFC 8209]. BGPsec is a RPKI-based technology which enables network operators to transitively validate whether a given BGP UPDATE - indeed - passed through the Autonomous Systems listed in the path. One way to think of BGPsec is as an ECDSA protected network of channels between a receiving EBGP node; and one (or many) routers in the BGP route's Origin AS. I think BGPsec can be useful to protect "private peering" at large scale, and another use case is to increase confidence in routing information distributed via IXP Route/Blackhole Servers. Right now, routing protocol researchers and network operators wishing to publish BGPsec Router Keys, also have to learn how to master "Delegated RPKI": a deployment model with a steep learning curve. I think there are benefits to the community if RIPE NCC appends an activity to the "RPKI Planning and Roadmap" to implement procedures to sign and publish BGPsec Router Keys via a PKCS#10 / PKCS#7 exchange, callable via both API and dashboard WebUI. What do others think? Kind regards, Job Relevant documentation: https://datatracker.ietf.org/doc/html/rfc8209 https://datatracker.ietf.org/doc/html/rfc8635

Support for "Publish in Parent" [RPKI RFC 8181]?
by Job Snijders 08 Oct '21

08 Oct '21

Hi working group, In recent mail threads the concepts of "Hosted RPKI" and "Delegated RPKI" came up, but as mentioned by Tim and Rubens, another flavor also exists! A "hybrid" between Delegated and Hosted, informally known as "publish in parent" (aka RFC 8181 compliant Publication Services). There are multiple benefits to the general RPKI ecosystem when RIRs and NIRs support RFC 8181: * Resource Holders are relieved from the responsibility to operate always online RSYNC and RRDP servers. * Reducing the number of Publication servers reduces overall resource consumption for Relying Parties. Consolidation of Publication Servers improves efficiency and is generally considered advantageous. * Helps avoid "reinventing the wheel": it might be better to have a small group of experts build a globally performant and resillient infrastructure that serves everyone, rather than everyone building the 'same' infrastructure. Other RIRs and NIRs are also working on RFC 8181 support. RFC 8181 is relatively new so it'll take some time before we see universal availability. NIC.BR (available): https://registro.br/tecnologia/numeracao/rpki/ APNIC (available): https://blog.apnic.net/2020/11/20/apnic-now-supports-rfc-aligned-publish-in… ARIN (planned): https://www.arin.net/participate/community/acsp/suggestions/2020/2020-1/ Is implementing RFC 8181 support something RIPE NCC should add to the https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/rpki-plan… ? What do others think? Kind regards, Job Relevant documentation: https://datatracker.ietf.org/doc/html/rfc8181
