Configuring join/prune message sizes
A large size of a join/prune message might result in loss of a larger amount of information if a message
is lost. You can set a small value for the maximum size of each join/prune message to reduce the impact
in case of the loss of a message.
By controlling the maximum number of (S, G) entries in each join/prune message, you can effectively
reduce the number of (S, G) entries sent per unit of time.

Command Remarks
1. Enter system view.

3. Configure the maximum size
of each join/prune message.

Optional.
8100 bytes by default.

number of (S, G) entries in
each join/prune message.

Optional.
1020 by default.
Configuring IPv6 PIM to work with BFD
IPv6 PIM uses hello messages to elect a DR for a shared-media network. The elected DR will be 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. To start a new DR election process immediately after the original DR fails, you can enable
IPv6 PIM to work with BFD on a shared-media network to detect failures of the links among IPv6 PIM
neighbors. You must enable IPv6 PIM to work with BFD on all IPv6 PIM-capable routers on a
shared-media network, so that the IPv6 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 IPv6 PIM-DM or IPv6 PIM-SM on the
interface.
