Setting the maximum size of a join or prune message

The loss of an oversized join or prune message might result in loss of massive information. You can
set a small value for the size of a join or prune message to reduce the impact.
To set the maximum size of a join or prune message:
Step
Enter system view.

Enter PIM view.

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.
To enable BFD for PIM:
Step
Enter system view.
1.
Enter interface view.
2.
Enable BFD for PIM.

Enabling PIM passive mode

To guard against PIM hello spoofing, you can enable PIM passive mode on a receiver-side interface.
The PIM passive interface cannot receive or forward PIM protocol messages (excluding register,
register-stop and C-RP-Adv messages), and it acts as the DR on the subnet. In BIDIR-PIM, it also
acts as the DF.
