Document: draft-ietf-babel-dtls-05 Reviewer: Dan Romascanu Review Date: 2019-06-25 IETF LC End Date: 2019-07-04 IESG Telechat date: Not scheduled for a telechat Summary: The document is Ready from a Gen-ART perspective. A couple of unclear / redundant statements are mentioned in the 'nits/editorial comments' bullet below. Major issues: Minor issues: Nits/editorial comments: 1. In section 2.1: > The default port for Babel over DTLS is registered with IANA as the "babel-dtls" port (UDP port TBD, see Section 4), and the port exchanging unencrypted Babel traffic is registered as the "babel" port (UDP port 6696). A reference would be desirable here. 2. In section 2.4 > Nodes MUST silently ignore any unprotected packet sent over unicast. When parsing an unprotected packet, a node MUST silently ignore all TLVs that are not of type Hello. Nodes MUST also silently ignore any unprotected Hello with the Unicast flag set. Is the last sentence necessary? Is this case not covered by the statement in the first sentence?
