Hi,

Writing as a co-Chair, I think we should determine the WG decision on
how to handle the IP source address for IPv4 ICMP generated by a Babel
router that has no interface with an IPv4 address. Juliusz presented
on this topic to our meeting at the March IETF meeting. See
https://datatracker.ietf.org/meeting/110/materials/slides-110-babel-babel-source-specific-and-v4-via-v6-02
specifically slides 5 through the end.

I think slides 10 and 11 cover the practical choices. Any feedback or
opinions welcome.

There is one other question in my mind. Does this draft really need to
be Experimental? I would be inclined to target it to Proposed
Standard.
(At least in theory an Experimental RFC should say what the experiment
is and how the results will be determined, although there certainly
are Experimental RFCs that fail to do this.)

Thanks,
Donald
