> And where is it forwarded to, since we are already at the DA? PSP operates at the n-1 segment end of the SR path so naturally after swapping DA it is forwarded to the segment end. Note that we are all along operating on the encapsulated header ... original packet including its original IPv6 header is sitting as passenger here.
So last segment here will received encapsulated IPv6 packet will decapsulate it and fwd based on the original DA. Seems very simple :) Cheers, R.
