Hi all,

 I have been selected as the Operational Directorate reviewer for this
 draft.

Review summary: 
I believe this document is "Ready with nits". And it would be better readability if the draft had added the reason for "obsolete" rather than "update".

comments below:

This draft obsoletes RFC8210 and section 1.2 list the following changes: 
1, new sections 5.12 ASPA PDU type
2, section 11 two ROA PDU race conditions
3, The protocol version number incremented  from 1 (one) to 2 (two)
4, the Section 7 has been updated accordingly

suggestions:
- Adds the reason why choosing "obsolete" RFC 8210 instead of "update", since the protocol version has been updated from 1 to 2
- The title "Protocol Version Negotiation" to be added to section 7 description.
-  Some major changes to other sections to be added:
   5.1 Flags adds ASPA PDU specific processing
   5.8. End of Data adds clarification text on version 1 changes
   14. IANA Considerations
