Hi Stewart,
draft-hu-spring-segment-routing-proxy-forwarding-14 does not use anycast
SID to protect a node failure. Another informational draft talks about using
anycast SID to protect a node failure.
Best Regards,
Huaimo

Regarding draft-hu-spring-segment-routing-proxy-forwarding-14
Do you need to provide any protocol to address this case?
In the diagram provided, if N1 acts as an anycast SID for N but at high cost,
then normal FRR node protection addresses the requirement of delivering the
packet to N1 which will strip SID N and sent the packet to the Node advertising
the next SID.
