NTAC Peering Working Group

Thanks to all who provided information. It sounds to me like Apple misunderstands how to advertise routes. If so, TR/CPS should not distort their routing to fix it. Hopefully the problem affects just Apple and people trying to reach Apple, so Apple will feel an incentive to fix it. Has TR/CPS contacted Apple about it?

Brad,

Thanks for your efforts looking into KanREN providing TR-CPS outbound transit routes.

I noted on this week's call that Internet2 has historically purchased a small amount of Level3 transit that has been used for special projects, conferences, and some Internet2 office locations.  It is currently a small commit delivered on GigE interfaces in a couple locations.  We are in the process of replacing these with 10G interfaces with a larger commit, in Los Angeles, WashingtonDC, and possibly Chicago.

Once this new capacity is in place, we could try an "experiment" where TR-CPS establishes BGP neighbors with Level3 and receives full routing tables.  These routes would be tagged, so that they would not be re-advertised to any participants.  No routes would be advertised to Level3.  We could then get an idea of the quantity of traffic and the scope of the issue.

Once we have more information, that could help inform us on the best direction to take.

I just an answer from Cox Communications that they will NOT remove the ACL on KanREN's transit port. So while we'd love to help this community that gives us so much this opportunity appears lost. Thanks for everyone's patience while we ran the topic to ground.

Here are the notes from yesterday’s meeting. Please feel free to correct any mistakes I have made.

 

1. Agenda Bash

2. Update on peering and TR-CPS/I2

·         Move Charter from 1GE to 10GE in Ashburn/Chicago/Dallas. Seattle to move to public exchange.

·         Capacity updates for Amazon for TR-CPS in Ashburn/Chicago for Amazon.

 

3. Network Weather Update

§  Nothing to update.

 

4. RPKI Update

·         Not much progress to report.

·         Will be a BoF at Global Summit.

 

5. Network DDoS Scrubbing Service Update

·         Close to signing contracts with Zenedge.

·         Pilots starting early-mid May.

·         Will be a Bof at Global Summit.

 

6. How to deal with the lack of a full routing table on TR-CPS (was: lack of transit on TR-CPS)

·         Issue Occurrence

o    only an issue with connectors/members that receive only a default route from their transit provided and more specifics from I2/TR-CPS

o    some times traffic gets blackholed  by TR-CPS or its peer

o    other times the peer will use their transit to deliver the traffic

·         Possible solutions:

o    members/connectors get full table from their provider.

§  Concern with requiring members/connectors having hardware needed for full table.

o    TR-CPS gets full routes from a transit provider. Don't advertise table to customers or advertise customer routes to provider.

§   Internet2 is in talks with Level(3) on increasing capacity to 10GE ports at Los Angeles/Chicago/Washington.

o    KanREN willing to provide full routes to TR-CPS as long as use is of limited occurrence and issues addressed with the I2 member. Possible issue is KanREN provider having filters in place which might drop the traffic from prefixes other than KanREN's. Brad to check with his Executive on that possibility and verify with KanREN's upstreams that prefixes are not being filtered.

§  Brad to hear back from Charter on ACL removal. All other KanREN transit providers will have no issue.

§  Could be setup quickly and used to get data for how common the issue is.

§  If KanREN is unable to provide, Dave Farmer can ask Big 10 Academic Alliance.

·         Concern with making sure the DDoS scrubbing service is taken into consideration.

o    Steve Wallace to write up a proposal.

7. AOB
