As for WLAN in infrastructure mode
draft-ietf-ipv6-rfc2462bis-08.txt, p. 26
suggests to not suppress multicast packets
with own MAC as ethernet source permanently for Duplicate address dedection
to work,
all own multicast packets will be looped back by WLAN Access point.
Thus MLDv1 must filter out MLDv1 report/Done messages with
One of Its own assigned IPv6 addresses as
IPv6 source address in order to make its state
Machine working correctly.
Or did I miss something ?
This means an additional influence of layer 2 behaviour onto
Layer 4 (MLDv1)!
(For MLDv2 the situation is the same ).
Comments welcome
Peter
