[routing-wg] RIPE 71, RIPE 72, and co-chair

Hi all,

RIPE 72 is approaching, and we're looking for two things.

First of all -- content!  If you have topics you'd like to see discussed, especially if you'd be willing to lead the discussion or presentation, then please let Joao and myself know via <routing-wg-chairs at ripe.net>.  In addition to the scheduled Routing WG session, we also plan to have a joint Routing-DB session to see if we can actually make some progress around the topic of non-authoritative routing registry information in the RIPE DB.

Secondly -- co-chair!  As I mentioned at the end of our last meeting, it is my turn to stand down as co-chair and we're on the lookout for volunteers to co-chair the WG.  A dated document describing the duties of the WG co-chairs is here:
	<https://www.ripe.net/publications/docs/ripe-542>
Since that was published the PC has taken on responsibility for leading the plenary sessions and a sub-group of the WG chairs collective now oversees the policy development process, so it's even easier than it was before.  If you have ideas about what we can do in the group, ideas about how to do it, and are able to attend most of the RIPE meetings, please let Joao and myself know via the email address above.  We will follow the process that we loosely documented on the list, archived at the following URL, and achieve consensus on a co-chair.
	<https://www.ripe.net/participate/ripe/wg/routing/routing-wg-chair-selection-process>

In a sign that I might be growing increasingly senile, or just drunk-in-charge-of-a-WG, I omitted to forward the draft minutes of RIPE 71 to the list when the NCC sent them around Christmas-time.  Please find them appended and let Joao and myself know of any changes.

Cheers,
Rob


Routing Working Group - RIPE 71
Thursday, 19 November 2015, 9:00-10:30
WG Co-Chairs:João Damas, Rob Evans Scribe: Anand Buddhev 1. Administrivia

WG co-chair Joao Damas opened the session. Joao asked for comments about the
draft minutes of RIPE 70. There were no comments, and he declared them
approved.

2. Isolario - Luca Sani

The presentation is available at:
https://ripe71.ripe.net/presentations/12-pres.pdf

Joao Damas asked about the future of this project, and whether it will be
supported. Luca answered that his institution plans to support it.

A Simple BGP - Alexander Azimov

The presentation is available at:
https://ripe71.ripe.net/presentations/162-A-Simple-BGP.pdf

Warren Kumari (Google) commented that there is a draft by Jared Mauch and Job
Snijders that achieves almost all the goals in this presentation.  Alexander
said that the draft came out around the same time he started his work.  He said
the draft is about filtering route leaks, whereas his work is about avoiding
them.

Randy Bush (IIJ) explained in detail about how this proposal is better than
Brian Dixon's proposal, because it allows both parties to agree to a policy in
the BGP OPEN message, rather than basing the route announcements on a marker
applied to routes. This makes it more robust to accidental route leaks.


RIS Updates - Colin Petrie, RIPE NCC

Kaveh Ranjbar (RIPE NCC) commented to the WG that at the last meeting, the community
asked for more RIS collectors to be deployed. He said that the RIPE NCC will
certainly expand into areas that are currently not well-covered, such as
Australia and New Zealand. He then asked the audience two questions and asked
for people to raise hands:

1. What scale should the expansion be at? Would a few more collectors, say 15,
be enough, or should be more like 50 to 100?

2. Whether RIPE NCC should deploy collectors in large ISP networks to get a
different view.

Joao Damas asked whether this was to get a view inside an ISP network, or still
get an external view but from an ISP's perspective. Kaveh said he meant the
latter.

Kaveh asked for a show of hands, and there was little support for this option.

Turris - Ondrej Filip

The presentation is available at:
https://ripe71.ripe.net/presentations/181-Turris-20151119-OF-RIPE.pdf

Mick O'Donovan (BT Ireland) commended Ondrej for this project. Joao Damas also
added his commendation and hoped that other manufacturers would pick up this
work, so that the quality of devices out on the Internet would improve.

Csaba Mate (NIIF/Hungarnet) asked whether there were any plans to release just
the board, without the switch ports. Ondrej said that they have to produce
large volumes to keep the costs reasonable, and so they don't plan on variants
at this early stage. He added that the hardware design is open, and said anyone
can produce a variant board by themselves.

Jen Linkova (Google) asked about IPv6 support. Ondrej said that it was
no longer neceesary to talk about IPv6 separately. He implied that it was a
given.


BGP collector Communities - Randy Bush and Emile Aben

The presentation is available at:
https://ripe71.ripe.net/presentations/159-151119.ripe-rtg.pdf

Jen Linkova (Google) asked why Randy classified a hijack as an intention of
misorigination and not as an intentional leak. Randy replied that it was
possible to divide the hijacks into categories besed on intent or no intent.

Warren Kumari (Google) asked what Randy meant by "route processing time". Randy
said he meant the time taken to start sending a full stream. He said they had
eliminated the RIB to FIB timing, because that was the classic trap.

Peter Hessler (Hostserver) asked how Randy would deal with an organisation that
has 32-bit ASN. Randy said he didn't know, and invited Peter to contribute to a
draft.

Ruediger Volk (Deutsche Telekom) commented that he would be unhappy if someone
tried to interfere with his organisation's internal communities setup. He said
he would not mind if a route collector asked for specific community tags, as
long as they described the whole topology, rather than just something specific
to that collector. Randy said that trying to describe how to do the whole
topology would be rather difficult. Ruediger then asked whether Randy was asking
for these specific communities to sent just to router collectors, or to other
peers to. Randy said that these communities needn't be sent to other peers, but
one could, if one wished.

Ruediger then added that if he tagged his routes with communities and sent them
to other peers, who then propagated them to Randy, he would see more
interesting stuff. Randy replied that he didn't really want to see that. He
said it was always possible to see which ASN a peer has because of the peering
relationship.


AOB

Sander Steffann said that the issue of communities for 32-bit ASNs had come up
in the Address Policy WG, and he asked them whether the routing WG should take
this to the IETF. There was overwhelming support for this in the APWG, so the
Routing WG will now take this to the IETF. He asked for questions. There were
none, and there was loud applause.

Dario Rossi asked for help with the Anycasters project. He said if anyone could
provide BGP feeds, it would be good, and invited people to talk to him.

Finally, Rob Evans announced that at the next RIPE Meeting, he would be
stepping down as co-chair. He said that if anyone wished to take on this role,
they should go and speak with him or Joao.
