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.

Your opinion on Internet monitoring and measurements - a 10min survey
by Pavlos Sermpezis 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

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

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-inā¦
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-planā¦ ?
What do others think?
Kind regards,
Job
