Thanks for pointing this out , I've run into a similar issue where the delegated IPv6-PD route uses the downstream router's global address instead of the link-local one. Since the global address can change or may not even be active (especially with SLAAC-only setups), using it as a gateway does cause reachability problems.
The link-local address would make much more sense here, as it's stable and always available on the local segment. Hopefully, this can be addressed in a future update or flagged for review. Appreciate you sharing this in detail, it's really helpful for those of us working with IPv6 setups! Want to explore more about how link‑local versus global addresses affect IPv6‑PD routing implementations and what tools like DeepSeek‑R1 reveal when analyzing these configurations?
