Working Group, MPLS Open DT,

The week before IETF 111 the Open DT met and agreed upon a text on
"indicators". The terminology we use is that somewhere in the label
stack there is an indicator tell the processing node that a specific
packet needs a certain set of Forwarding Actions, for example some iOAM
action might be required. To support the forwarding action there is
often ancillary data with the packet.

The text the DT produced is about the indicators, a companion text on
ancillary data will follow.

<tp>

In earlier discussions,the issue arose as to whether or not more than one label could be flagged as Bottom of Stack.

This text seems to assume that there can only be one, in which case, that is an assumption worth stating in m view.

Tom Petch

The text was discussed in the Joint meeting and reported to the MPLS
working group at IETF 111. The Open DT itself can only propose, the text
is therefore now sent out to the working group for review and consensus
call.

The proposed text is found at:
https://trac.ietf.org/trac/mpls/wiki/2021-07-22-agenda

Please review the proposed text and comment on the MPLS wg mailing list
(mpls@ietf.org).

We plan to keep the consensus call open until 2021-08-20.
