  1. To Insert AS Origin field into APNIC IP address database Xing Li Shuang Zhu CERNET 2001-08-30

  2. Problem Statement • APNIC’s IRR service • APNIC needs to provide • Wrong IP prefix announcement in the BGP routing table from PA (holes) • Make chaos in the global routing table (-: • Distinction of PA and PI IP blocks • How about based on AS origin?

  3. Example BGP routing table entry for 202.120.0.0/15, version 36730882 Paths: (2 available, best #2) Advertised to peer-groups: rr-pop 64534538, (aggregated by 4538 202.112.61.253) 198.32.136.146 (metric 445900) from 165.117.1.133 (165.117.1.133) Origin IGP, metric 4294967294, localpref 100, valid, internal, atomic-aggregate Community: 2548:201 2548:666 3706:152 64534538, (aggregated by 4538 202.112.61.253) 198.32.176.38 (metric 345600) from 165.117.1.219 (165.117.1.219) Origin IGP, metric 4294967294, localpref 100, valid, internal, atomic-aggregate, best Community: 2548:204 2548:666 3706:153

  4. Example BGP routing table entry for 202.120.232.0/21, version 36649952 Paths: (2 available, best #2) Advertised to peer-groups: rr-pop 6453 4799 198.32.136.146 (metric 445900) from 165.117.1.133 (165.117.1.133) Origin IGP, metric 4294967294, localpref 100, valid, internal Community: 2548:201 2548:666 3706:152 6453 4799 198.32.176.38 (metric 345600) from 165.117.1.219 (165.117.1.219) Origin IGP, metric 4294967294, localpref 100, valid, internal, best Community: 2548:204 2548:666 3706:153

  5. Example of Current APNIC whois database inetnum: 202.120.0.0 - 202.120.63.255 netname: SJTU-CN descr: Shanghai Jiaotong University country: CN admin-c: SW1-CN tech-c: ZG1-CN notify: dbmon@apnic.net changed: hostmaster@apnic.net 950222 source: APNIC

  6. Example of RA whois database route: 202.120.0.0/15 descr: CERNET Center Tsinghua University Central Bldg. Bejing P. R. China origin: AS4538 member-of: RS-COMM_NSFNET notify: yjh@noc5.net.edu.cn mnt-by: MAINT-AS4538 changed: yjh@noc5.net.edu.cn 19951213 source: RADB

  7. Suggestions AS origin • as a mandatory field in the APNIC whois database • as a required procedure for the IP address application

  8. Example inetnum: 202.120.0.0 - 202.120.63.255 netname: SJTU-CN descr: Shanghai Jiaotong University country: CN origin: AS4538 admin-c: SW1-CN tech-c: ZG1-CN notify: dbmon@apnic.net changed: hostmaster@apnic.net 950222 source: APNIC

  9. Suggested Application Form #[NETWORK TEMPLATE V:5.0]# netname: descr: descr: country: origin: admin-c: tech-c: remarks: changed: mnt-by: source: APNIC

  10. Comments • Provide APNIC’s “IRR lit” service • APNIC is the Authority • Define PA and PI based on AS origin • Owns AS = PI, upper-stream’s AS = PA • Check of the immediate use of IP address • Own AS or upper-stream’s AS • Evaluate Confederation membership • number of AS

  11. Questions?
