Enabling Bfd For Pim; Displaying And Maintaining Pim - HP 6125XLG Ip Multicast Configuration Manual

Enabling BFD for PIM

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 ages out. However, 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 on a shared-media
network to detect failures of the links among PIM neighbors.
You must enable BFD for PIM on all PIM 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.
To enable BFD for PIM:
Step
1. Enter system view.
2. Enter interface view.
3. Enable BFD for PIM.
