Re: [Pce] WG Adoption of draft-chen-pce-pcep-ifit-06

Hi Giuseppe,
I have a question about your statement:

But if nodes on the path do not support some capabilities, it is not a big
issue. Indeed, both Alternate Marking and IOAM documents specify that nodes
that do not support a specific functionality will forward the packet
without any changes to the data fields and they are simply not considered
in the measurement.

Is the expectation that a packet marked with IOAM or AltMarking will be
forwarded by a non-supporting node applies to all IETF networking
technologies, for example in an MPLS network?

Regards,
Greg
