the two captures are at: http://snapon.lab.bufferbloat.net/~cero2/babcap/
There's nothing obviously wrong. Here's an example of a source-specific
TLV (the one at time 06:20.362230 in the wifi capture):
0d 16 02 20 00 00 06 40 65 8a 00 e0 40 00 20 01 04 70 82 36 02 61 02 00
Type = 0d (13)
Length = 16 (32)
AE = 02
Flags = 20
Plen = 00
Omitted = 00
Interval = 0640 (16s)
Seqno = 658a
Metric = 00e0 (224)
Prefix = (empty) (::)
Src Plen = 40 (64)
src Omitted = 00
src Prefix = 20 01 04 70 82 36 02 61 (2001:0470:8236:0261:0261::)
Sub-TLV: 02 00 (diversity empty)
Matthieu, do you have any ideas?
I don't see any problem with that TLV.
However, an interesting one is the last of that packet (babel.pcap):
00:05:20.966837 IP6 (class 0xc2, hlim 1, next-header UDP (17) payload length:
232) fe80::28c6:8eff:febb:9ff0.6696 ff02::1:6.6696: [udp sum ok] babel 2 (220)

The last line show we have sent a 'from ::/128', which is martian.
Who is fe80::28c6:8eff:febb:9ff0 ? Does it have a config file ? (If yes,
which contents ?)
