Hi Ron,

When reading the CRH draft, I have a question about how CRH support SFC?

For example, we have a SID List [S1, S2, S3, S4, S5], and S3 is a SFC related 
SID, how to indicate that? By PSSI? [1]

But how to know which segment endpoint node/egress node should process this 
PSSI? At the beginning of the SRm6 design, this is described in [2]. But you 
deleted the containers [2].

Without that, I don't really understand how SFC can be supported.


Best,
Cheng
