RFC 8175, "Dynamic Link Exchange Protocol (DLEP)", June 2017

Source of RFC: manet (rtg)

Errata ID: 6472
Status: Held for Document Update
Type: Technical
Publication Format(s) : TEXT

Reported By: Rick Taylor

Section 12.4, para 2 says:

A Peer Offer Signal MUST be encoded within a UDP packet.  The IP source and destination fields in the packet MUST be set by swapping the values received in the Peer Discovery Signal.  The Peer Offer Signal completes the discovery process; see Section 7.1.

It should say:

A Peer Offer Signal MUST be encoded within a UDP packet. If the Modem is not including IPv4 and IPv6 Connection Point Data Items in the Peer Offer Signal, then the IP source field in the packet MUST be set to the unicast address the router must use when connecting the DLEP TCP session, otherwise any valid local address MUST be used.  The IP destination field in the packet MUST be set to the IP source field value received in the Peer Discovery Signal.  The Peer Offer Signal completes the discovery process; see Section 7.1.

Notes:

The original text will not result in a valid unicast IP packet.

=====
AD Note: The original text is clearly wrong. There has been discussion in the WG about the proper wording for the "corrected text", but no definitive conclusion has been reached. More discussion is clearly needed so I am marking this report as Held for Document Update.
