Internet2 Network Updates

1. Looking at updating the aggregation routers in Ashburn starting on or around September 9th (expect to last 3-4 days)
2. 2 new 100g connections for Cloud Connect are coming up in Chicago
3. Currently have 4 locations where temporary routers (Cisco 55A1) have been deployed to work around a Cisco software limitation (Cisco 8202). This issue is specific to Cloud Connect services.
4. Recent performance issue (the last 24 hours):

                                                              i.      Yesterday evening one of the international NRENs (in the middle-east) has started advertising I2's R&E routes to their upstream transit provider

                                                             ii.      Campuses started encountered difficulties with Microsoft and Google related services; most of these issues appear to be related to the campus advertising more specific routes to I2 than to their commodity providers. However it may have impacted campuses where their AS path was shorter when routed through this NREN

                                                           iii.      Performance issue was due to high latency and low bandwidth (1g) on the impacted link to the NREN

                                                           iv.      Impact from the issue was resolved by shutting down the peering once

                                                             v.      I2 is looking for ways to detect and prevent this type of issue, but solutions are challenging

                                                           vi.      Campuses and regionals should investigate solutions such as BGP Alerter that might help them diagnose and resolve future issues

5. Campus border route policy best practices

1. David Farmer:

                                                              i.      Currently adjusting to recent I2PX changes; merging I2PX & R&E tables

6. Any other business?

1. Steve Wallace:

                                                              i.      In July a connected network saw some of their IP space being announced overseas

                                                             ii.      Mitigated most of the issue by creating a ROA (they had the appropriate agreement with ARIN); some issues continued with parts (but not all) of Google's network

                                                           iii.      Issue lasted for weeks

                                                           iv.      Currently 800 organizations connected to I2 have appropriate agreements but lack the ROA

2. Brief discussion surrounding VoIP/SIP in light of recent issues
