MBGP is an extension of the MP-BGP for exchanging multicast routing information among 
different ASs. 

For the SSM model, multicast routes are not divided into intra-domain routes and inter-domain 
routes. Because receivers know the positions of the multicast sources, channels established 
through PIM-SM are sufficient for the transport of multicast information. 

Layer 2 multicast protocols 

In 

Figure 9

, Layer 2 multicast protocols include IGMP snooping, MLD snooping, PIM snooping, IPv6 

PIM snooping, multicast VLAN, and IPv6 multicast VLAN.

IGMP snooping and MLD snooping: 

IGMP snooping and MLD snooping are multicast constraining mechanisms that run on Layer 2 
devices. They manage and control multicast groups by monitoring and analyzing IGMP or MLD 
messages exchanged between the hosts and Layer 3 multicast devices. This effectively 
controls the flooding of multicast data in Layer 2 networks.

PIM snooping and IPv6 PIM snooping: 

PIM snooping and IPv6 PIM snooping run on Layer 2 devices. They work with IGMP snooping 
or MLD snooping to analyze received PIM messages. Then, they add the ports that are 
interested in specific multicast data to a PIM snooping routing entry or IPv6 PIM snooping 
routing entry. In this way, multicast data can be forwarded to only the ports that are interested in 
the data. 

•

 

Multicast VLAN and IPv6 multicast VLAN: 

Multicast VLAN or IPv6 multicast VLAN runs on a Layer 2 device in a multicast network where 
multicast receivers for the same group exist in different VLANs. With these protocols, the Layer 
3 multicast device sends only one copy of multicast to the multicast VLAN or IPv6 multicast 
VLAN on the Layer 2 device. This method avoids waste of network bandwidth and extra burden 
on the Layer 3 device. 

Multicast packet forwarding mechanism 

In a multicast model, receiver hosts of a multicast group are usually located at different areas on the 
network. They are identified by the same multicast group address. To deliver multicast packets to 
these receivers, a multicast source encapsulates the multicast data in an IP packet with the multicast 
group  address  as the destination address. Multicast routers on the forwarding paths  forward 

 IPv4/IPv6 multicast packets (S1, G1)
