soluti
on
l
Upstream
IGMP
packets: The
MDU
performs
IGMP proxy
to terminate
IGMP
packets
transmitted
from the user
side,
encapsulate
the packets
with an
MVLAN tag
on the
network side,
and send the
packets
upstream.
l
Downstream
multicast
service flows:
The MDU
replicates
multicast
packets based
on user ports
and
multicasts
downstream
packets
among
MVLANs.
l
Upstream
IGMP
packets: The
OLT
performs
IGMP proxy
to terminate
IGMP
packets
transmitted
from the user
side,
encapsulate
the packets
with an
MVLAN tag
on the
network side,
and send the
packets
upstream.
l
Downstream
multicast
service flows:
The OLT
replicates
multicast
packets based
on GE ports
with
MVLANs
unchanged.
This solution is
recommended.
