Hi Ron,
1) and 2 ) are fine. IMO: 3) works under certain conditions but not all. I add David Black (TSVWG chair) to the thread. He can provide the thorough check.

OLD> Because the IPv6 delivery header does not include a checksum of its own, it is subject to corruption. However, even if the delivery header is corrupted, to likelihood of that corruption resulting in misdelivery of the payload is extremely low. <OLD NEW> Because the IPv6 delivery header does not include a checksum of its own, the destination address in the delivery header is subject to corruption. If the destination address in the deliver header is corrupted, the following outcomes are possible: 1) The delivery packet is dropped because the new destination address is unreachable 2) The delivery packet is dropped because the new destination address is reachable, but that node is not configured to process GRE delivery packets from the ingress 3) The delivery packet is processed by a GRE egress other than that which was originally specified by the GRE ingress. Processing options are: a. The payload packet is dropped because the payload destination is unreachable from the node that processed the delivery packet b. The payload packet is delivered to its intended destination because the payload destination is reachable from the node that processed the delivery packet All of these outcomes are acceptable. <NEW Ron From: Lucy yong [mailto:lucy.y...@huawei.com] Sent: Monday, March 30, 2015 4:50 PM To: Zuniga, Juan Carlos; int-area@ietf.org<mailto:int-area@ietf.org>; i...@ietf.org<mailto:i...@ietf.org> Cc: draft-ietf-intarea-gre-i...@tools.ietf.org<mailto:draft-ietf-intarea-gre-i...@tools.ietf.org>; intarea-cha...@ietf.org<mailto:intarea-cha...@ietf.org> Subject: RE: Start of WGLC for draft-ietf-intarea-gre-ipv6 Thanks authors to add section 4.1. I am not sure if the statement of “However, even if the delivery header is corrupted, to likelihood of that corruption resulting in misdelivery of the payload is extremely low.” is proper. IPv6 requires the end point/upper layer to deal with the header corruption. Could we state that this is the difference from gre-in-ipv4 instead?
