3. Agenda UDL Operation UDL 13Mbps bandwidth extension IPv4 Routing on UDL Other Routing Issues New network design in SFC Security

4. UDL Operation

5. Topics Report –UDL13Mbps extension and UDstation installation done –Keio establish maintenance contracet with UDcast for UDstation and UDbox –Backup UDstation and UDboxes will arrive soon Backup UDStation box –Coming Soon –TBD Later MTU 1500 on UDL –MTU 1452 on UDL should be legacy (SONY Feed problem) –TBD Later Issues on UDstation 13Mbps Performance –Configuration is 13Mbps but actual output by MRTG is around 10Mbps –TBD Later IPv4 routing on UDL –Install Private IPv4 for routing on the UDL (schedule and design) –TBD Later

6. Backup UDstation and UDbox Expected arrival date Direction of operation Expected topology including backup UDstation

7. MTU 1500 on UDL Current status –1500 on sfc-udl-feed and ITB ospf6d ipv6 ospf6 mtu 1452 –1452 on others –OSPFv2 with ITB is okay –OSPFv3 with all uses if mtu 1452 definition in ospf6d.conf AI3 Meeting Operator Meeting – RR UDL I/F MTU 1500 – –TS MTU

8. Issues on UDStation 13Mbps Performance

9. UDStation 13Mbps Performance TCP tests on UDL: –Multiple wget sessions on SFC RO2: web server is sfc-cpu, output is /dev/null MTU is 1500 Output is around 10Mbps (less than smartbit results)

10. Comparing the Results iperf TCP results: Around 11Mbps Wget results: Around 10Mbps MRTG Sfc-udl-feed:bge1

11. Testing direction and announcement Do more tests to confirm –iperf vs wget –Smartbit UDP vs iperf UDP If wget or iperf is less than Smartbit: –Why? –Contact UDcast? Use tcpdump, then gets more accurate number UDL maybe blocked for testing

12. IPv4 routing on UDL

13. Routing for AIT and ITB BDL bandwidth changes due to UDL 13Mbps migration –SFC-ITB and SFC-AIT are 128kbps OSPFv2 is running on UDL Neighbor: ITB, AIT should be neighbor, too. Prefer routes via UDL than BDL

14. Install Private IPv4 for routing on the UDL Background Discussion Design Schedule

15. Other Routing Issues

18. M6bone Current status: –Tunnel with RENATER using sfc-c7200-gate –Failure on advertising AI3 prefix to RENATER Trouble shooting is on-going Next: –Move c7200 to AI3 rack –BGP peers Fujisawa cisco 12000 –Push APAN-JP and TEIN2 to activate PIM- SM and MBGP

19. FreeBSD-specific Issues Routing socket issue FreeBSD 4.10 ~ –Kernel doesnt inform all route deletes if too many deletes in a small period Ex: route flush –Result: Zebra doesnt reinstall all routes deleted by, e.g., route flush Husni patched zebra code –Already run on some routers in AI3 –Should let others know

20. Multicast Routing: XORP Issues SOI Asia is using XORP 1.1 –Some bugs. E.g.: doesnt update MRIB if there are changes in kernel Should upgrade to XORP 1.3 + patches –Unpatched XORP 1.3 has next-hop interface problem in MRIB

21. AI3 SFC Network Middle-term Design

22. Todos for preparation Show the final topology Show the intermediate topology for the near future (Change topology with current cisco) and discuss routing and addressing

24. Generic Requirement Less operational cost and more stability –Integrate some PC routers to Cisco routers –Distinguish challenge and stable operation (ex. sfc- udl-feed) Capability of fiber optic connections in backbone Redundancy against hardware troubles –Backup for core routers –Backup for UDstation Interoperability between challenge and stabile operation IPv6 deployment

25. Less operational cost and more stability Integrate some PC routers to Cisco routers –Decrease the risk for hardware trouble Trials with PC router like sfc-udl-feed v.s backup using Cisco router –Need to clear out the minimum interoperability between challenge and stable operation

26. Capability of fiber optic connections in backbone For the future operation, routers and switches connecting to the backbone may need gigabit Ethernet interface

27. Redundancy against hardware troubles Duplicate some important routing entities –sfc-gate –sfc-udl-feed –sfc-sat –sfc-udstation

28. IPv6 deployment Server upgrade –WEB Cache –DNS –SOI-Asia applications? Routing in the UDL network –IPv6 for all SOI-Asia partners –Private IPv4 for a part of partners BDL partners IPv6-only connection for new RO sites
