What's Changed
This revision contains the following very minor changes from the ID14
version.
o For clarity, each message type is now defined separately in
Section 3.1.
o We added more precise and complete rules for accepting Path
messages for unicast and multicast destinations (Section
3.1.3).
o We added more precise and complete rules for processing and
forwarding PathTear messages (Section 3.1.5).
