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:

The default setting is 8100 bytes.
Enabling BFD for IPv6 PIM
If a DR on a shared-media network 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, you can
enable BFD for IPv6 PIM to detect link failures among IPv6 PIM neighbors.
You must enable BFD for IPv6 PIM on all IPv6 PIM routers on a shared-media network. For more
information about BFD, see
High Availability Configuration Guide
.
You must enable IPv6 PIM-DM or IPv6 PIM-SM on an interface before you configure this feature on
the interface.

Enabling IPv6 PIM passive mode
To guard against IPv6 PIM hello spoofing, you can enable IPv6 PIM passive mode on a receiver-side
interface. The interface cannot receive or forward IPv6 PIM protocol messages (excluding register,
