Configuring PIM Features
Routers use PIM to maintain forwarding tables for forwarding multicast diagrams. When you enable
multicast routing on the ASA, PIM and IGMP are automatically enabled on all interfaces.
Note PIM is not supported with PAT. The PIM protocol does not use ports, and PAT only works with protocols
that use ports.
This section describes how to configure optional PIM settings and includes the following topics:
