NETGEAR 8800 User Manual 
Note:  
If a port is blocked by Layer 2 protocols, that port is removed from 
the egress list of the cache. This is done dynamically per the port 
state.
For most situations, you do not need to manually configure ports to receive the MVR 
multicast streams. But if one of the forwarding rules denies forwarding to a port that requires 
the streams, you can manually receive the MVR multicast streams by using the following 
command:
configure mvr vlan <vlan-name> add receiver port <port-list>
Inter-Multicast VLAN Forwarding
In 
on page 749, only simple topologies are considered, in which 
subscribers on different VLANs access a multicast VLAN. There are topologies where 
streams need to be forwarded onto another multicast VLAN, as shown in 
. In this 
figure, a Multicast Service Provider (MSP) multicast VLAN is attached to ports 1:1-2 on both 
switches, SW1 and SW2. On the customer side, another multicast VLAN, delivers multicast 
streams to other switches around the ring.
Figure 91. Inter-Multicast VLAN Forwarding
In this topology, a multicast stream can be leaked into the customer multicast network 
through either switch SW1 or SW2. However, as described in 
packets are not forwarded to router ports (ports 1:4 and 1:5 can be router ports if SW2 is an 
IGMP querier). To get around this, MVR needs to be configured on CustVlan either on SW1 
or SW2. Since the forwarding rules apply only to non-MVR VLANs, traffic from one MVR 
VLAN is leaked into the router ports of another VLAN, if MVR is enabled on that.
