Hello Dan, and thanks for your review. Comments inline.
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.
What reference do you have in mind? This paragraph already has a
reference to Section 4 (IANA Considerations).
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?
The Unicast flag is a bit in the Babel packet. This statement instructs nodes
to ignore a Hello TLV which was received over multicast but has the unicast flag set.
Thanks,
David
