Glossary

If the shortest path from C to the source is through switch B, and the interface between C and B

does not have PIM-SM enabled, then C cannot switch to the SPT. C discards data that comes

through the shared path tree (that is, through A). The simple workaround is to enable PIM on VLAN1

between C and B.

Source filtering

The system can report interest in receiving packets from only a specific source address (INCLUDE),

from all but specific source addresses (EXCLUDE), or sent to specific multicast addresses. IGMPv3

interacts with PIM-SM, PIM-SSM, and snooping to provide source filtering. For more information,

see Configuring IP Multicast Routing Protocols on Avaya Virtual Services Platform 9000,

NN46250-504.
