Enabling BFD for PIM
If a DR on a shared-media network fails, a new DR election process does not start until the DR ages
out. In addition, it might take a long period of time before other routers detect the link failures and
trigger a new DR election. To start a new DR election process immediately after the original DR fails,
enable BFD for PIM to detect link failures among PIM neighbors.
You must enable BFD for PIM on all PIM routers on a shared-media network. For more information
about BFD, see
High Availability Configuration Guide
.
You must enable PIM-DM or PIM-SM on an interface before you configure this feature on the
interface.
