So, what we should have is a= n LSE containing the forwarding actions followed by LSEs for each forwardin= g action that requires ancillary data. These LSEs should be in the same or= der in which the forwarding actions are defined; if forwarding actions 1, = 3, and 5 require ancillary data, then following the LSE containing the forw= arding actions there should be three LSEs, for forwarding actions 1, 3, and= 5. I also think we need to specify that a transit node should only process the= forwarding actions it understands and ignore the others, and that when con= structing the FAI LSEs the ingress node should only include forwarding acti= ons understood both by it and by the egress node. I think the implication = of these rules is that a every node needs to understand every bit in the fo= rwarding actions up to a given bit position. I.e., it can't selectively su= pport individual forwarding actions. =20 Yours Irrespectively, John Juniper Business Use Only > -----Original Message----- > From: mpls On Behalf Of Loa Andersson > Sent: Tuesday, September 7, 2021 4:46 AM > To: mpls@ietf.org > Cc: pals-chairs@ietf.org; mpls-chairs@ietf.org; DetNet Chairs chairs@ietf.org> > Subject: [mpls] Open DT agenda for 2021-09-09 >=20 > [External Email.
