Hi SPRING WG, I have a question about Anycast-SID. 1- In RFC 8402 section 3.2, it mentioned that “Node-SID MUST NOT be associated with a prefix that is owned by more than one router within the same routing domain”. Also, in section 3.3, it mentioned that “ An IGP-Anycast segment MUST NOT reference a particular node”.
2- Also, we have N-Flag “isis-segment-routing-extensions-23” that indicates whether Prefix-SID related to a node or not. My questions are: 1- What happens if I don’t implement these rules in network? 2- What happens if I set anycast-sid on multiple nodes, but I don’t set "n-flag clear” under loopback configuration? 3- Why "IGP-Anycast segment MUST NOT reference a particular node” ?
