Nope. Node can advertise two SIDs or PSP in a given network may be a well know function (to limit IGP burden) Example: odd SID includes PSP and even SID does not.
O*A*M packets can use on the exact same path but the penultimate hop traversal is directed by even SID and is not subject to PSP. Done. Thx, R. On Sun, Mar 1, 2020 at 5:50 AM Joel M.
