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

2. 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. 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 6453 4538, (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 6453 4538, (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. 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

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

10. 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
