Summary:

Major issues:

Section 3 states BRAS and CPE are in different administrative domains. But
Section 5.2 assumes BRAS can advertise routes using IGP inside the SR domain.
This is contradicting: a BRAS cannot advertise in a domain it does not belong
to.

Section 5.5 has a long sentence: “The first DHCPv6 relay agent needs to record
the SRv6 Locator assigned by the DHCPv6 server, including SRv6 Locator
information, lifetime, etc.”

Questions:
- Why must a relay record the lifetime if BRAS/server already does?
- What happens if the relay reboots?

- Does DHCPv6 server always install route?
In multiple places: “MAY install a local SRv6 Locator route…”

Minor issues:
- In Section 5.1, it says Figure 2, but the figure is actually Figure 4.

Nits/editorial comments:
Several terms appear with inconsistent capitalization or spelling:
- IA_SRv6_Locator vs IA_SRV6_LOCATOR
- IALocator-Options vs IA_Locator-Options
- SRv6 SID Locator length (LOC-Len) sometimes written SRv6 SID locator length.
It would be good to ensure consistent capitalization and spacing across
document.

Grammar issues:
- “Telecom providers can use its IP Metro and Backbone networks…”
Should be: their networks.

- “SRv6 policies needs to be configured…”
Should be: policies need

Warm Regards,
