If I have
A --------- B --------- C
and A-B is prefix1::/64 and B-C is prefix2::/64 and prefix1 != prefix2
then subnet local multicast packets are not forwarded through B, right?
If I have
A --------- B --------- C
and A-B is prefix3::/64 and B-C is prefix3::/64 (a multi-link subnet)
then subnet local multicast packets are forwarded through B, right?
And if I have
A --------- B --------- C
And A-B is prefix1::/64 and prefix3::/64, and B-C is prefix2::/64 and
prefix3::/64 (prefix1 != prefix2, prefix1 != prefix3, prefix2 != prefix3)
then subnet local multicast packets arriving at B are ..... ???
I also assume that the necessary two implementations of all of this, that
will allow a doc containing it to advance to DS have been documented in
the implementation report?
