Hi,
I would like some clarification about the treatment of the SRH by an end point
(the node that its loopback matches the DA field),
In section 3 :
You say that the
C-flag: Clean-up flag. Set when the SRH has to be removed from
the packet when the packet reaches the last segment.
Which mean that the last node inspects the SRH flags if the c-flag is set, the
node has to remove the SRH before sending the packet to its final destination.
But In section 4.3.
You say that the node that decrements the Segments left pointer has to check if
the c-flag is set when the new value of the segments left point is equal to
zero,
If the c-flag is set and the segments left pointer == 0 then remove the SRH,
What is confusing for me is that the node that decrements the pointer is not
the last node in the SR path (behavior similar to PHP for MPLS) , which I find
in direct contradiction with section 3.
Another question if a node receives a packet with the already segment left ==
0, what should that node do with the packet(e.g., drops it?)
Bests.
