Information About PIM and PIM6

Note Beginning with Cisco NX-OS Release 5.0(2a), Bidirectional Forwarding Detection (BFD) supports PIM. See
the Cisco Nexus 7000 Series NX-OS Interfaces Configuration Guide.
PIM, which is used between multicast-capable routers, advertises group membership across a routing domain
by constructing multicast distribution trees. PIM builds shared distribution trees on which packets from
multiple sources are forwarded, as well as source distribution trees on which packets from a single source are
forwarded. For more information about multicast, see Information About Multicast.
Cisco NX-OS supports PIM sparse mode for IPv4 networks (PIM) and for IPv6 networks (PIM6). In PIM
sparse mode, multicast traffic is sent only to locations of the network that specifically request it. You can
configure PIM and PIM6 to run simultaneously on a router. You can use PIM and PIM6 global parameters
to configure RPs, message packet filtering, and statistics. You can use PIM and PIM6 interface parameters
to enable multicast, identify PIM borders, set the PIM hello message interval, and set the designated router
(DR) priority. For more information, see Configuring PIM or PIM6 Sparse Mode.
