Hi PCE WG,

Support adoption. Seems reasonable to convey flex algo related constraint and status between PCE and PCC, and the document is written quite clear.

One general potential question/concern is the SR-ERO encoding of A-bit/Algorithm value, since it describes it comes after other optional fields. Assuming one day other documents continue to specify optional fields as well (backed by the flags), do we run the risk of potential mis-ordering of values between implementations? or is the expectation for all values to be in the same sequence of the flag definition? Seems like it’s reinventing tlv without the tlv overhead, but since the original SR-ERO object is already variable values, it does fit, and at this moment I have no other alternative suggestion...

Thanks
Andrew
