Multicast Boundary

Multicast Boundary

Usage Scenario

Multicast boundaries are used to control multicast information transmission by allowing the multicast information of each multicast group to be transmitted only within a designated scope. A multicast boundary can be configured on an interface to form a closed multicast forwarding area. After a multicast boundary is configured for a specific multicast group on an interface, the interface cannot receive or send multicast packets for the multicast group.

Principles

As shown in Figure 6-6, Device A, Device B, and Device C form multicast domain 1. Device D, Device E, and Device F form multicast domain 2. The two multicast domains communicate through Device B and Device D.

Figure 6-6 Multicast boundary
NOTE:

Interfaces 1 and Interfaces 2 in this example are GE 1/0/0, GE 2/0/0, respectively.



To isolate the data for a multicast group G from the other multicast domain, configure a multicast boundary on GE 1/0/0 or GE 2/0/0 for group G. Then, the interface no longer forwards data to and receives data from group G.
