Hi Aihua, Thanks for your comments.
The allocation process of SRv6 Locator in this draft follows the DHCPv6 prefix allocation process. Compared to IPv6 prefix allocation process, the allocation process of SRv6 prefix has some new requirements. For example, while assigning the Locator prefix to the client, it is also necessary to inform the length of Block, Func, and Args of Locator in the DHCPv6 message. At the IETF-115, The Chairs and experts from DHC WG suggested that we define a new Identity Association for SRv6 Locator (IA_SRV6_LOCATOR) option specifically for assigning SRv6 Locators to distinguish it from the existing Identity Association for Prefix Delegation (IA_PD) option. We modified the draft accordingly. B.R.

As the draft descripted, it is valuable to simplify the CPEs to join in the SRv6 domain. I wonder whether if this could be done by current existed IPv6 prefix allocation process.

Now we have uploaded the replacement draft [draft-cheng-spring-distribute-srv6-locator-by-dhcp]. Document Link: https://datatracker.ietf.org/doc/draft-cheng-spring-distribute-srv6-locator-by-dhcp/ This proposal follows the IPv6 Prefix allocation process of DHCPv6 and proposes a method of dynamically assigning SRv6 Locator to endpoints through DHCPv6. It defines an Identity Association for SRv6 Locator (IA_SRV6_LOCATOR) Option. With this option, Locator Prefix and Block-len, Func-len, Args-len can be dynamically distributed for SRv6 endpoints in SRv6 network. Based on this method, centralized management of SRv6 Locator prefix resources can be achieved, and network deployment can also be effectively simplified. The draft has been presented in DHC WG at IETF115 and 116, as well in SPRING WG at IETF116. The feedback were positive. Sincerely ask for your feedback.
