Enabling PIM to work with BFD
PIM uses hello messages to elect a DR for a shared-media network. The elected DR is the only multicast
forwarder on the shared-media network.
If the DR fails, a new DR election process will start after the DR is aged out. However, it might take a long
period of time before detecting the link failures among the PIM neighbors and starting a new DR election
process. To start a new DR election process immediately after the original DR fails, enable PIM to work
with BFD on a shared-media network to detect failures of the links among PIM neighbors. You must
enable PIM to work with BFD on all PIM-capable routers on a shared-media network, so that the PIM
neighbors can fast detect DR failures and start a new DR election process. For more information about
BFD, see High Availability Configuration Guide.
Before you configure this feature on an interface, be sure to enable PIM-DM or PIM-SM on the interface.
