Re: [6lo] New Version Notification for draft-ietf-6lo-path-aware-semantic-addressing-01.txt

["Pascal Thubert (pthubert)" <[e-mail]>]

Hello Luigi:

I was thinking; maybe we can use the I-Field defined in RFC 8505. It signals what the opaque field is about, see fig 1 of RFC 8505.
So if we pick one value of the I-Field (say I=1) to mean PASA, we have the whole opaque field to indicate whatever PASA needs to pass.
OTOH, if we do not need 8 bies, then we can define I=1 to "more flags", in which case the Opaque can be a extended bit field of 8 bits.
So what do we need exactly?

All the best

Pascal
