Re: [IPsec] Fwd: New Version Notification for draft-colitti-ipsecme-esp-ping-02.txt

Thanks for adding the use cases section, it's useful to me.

In section 5, after adding the third scenario of not receiving the ESP Echo Reply packet, there are two points in the following paragraph that also need adjustments.
1. s/the sender can not distibguish those two scenarios/the sender can not distinguish those three scenarios.
2. The following sentence isn't correct as there are 3 possible situations.
   Therefore
   the sender SHOULD NOT treat lack of response as an indicator of end-
   to-end connectivity issues until an explicit confirmation of ESP Echo
   support by the peer is received.
Maybe change it to "Therefore the sender SHOULD NOT treat lack of response as an indicator of end-to-end connectivity issues" or "Therefore the sender SHOULD NOT treat lack of response as an indicator of end-to-end connectivity issues until it receives explicit confirmation that the peer supports and the intermediate nodes allow ESP Echo".

Regards & Thanks！
