If you want to support IETF SFC, use the IETF Proposed Standard, NSH.

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
