5. Set the interval to send
join/prune messages.
ipv6 pim timer join-prune interval
By default, the interval to send
join/prune messages is 60
seconds.
6. Set the joined/pruned state
holdtime timer.
ipv6 pim holdtime join-prune time
By default, the joined/pruned state
holdtime timer is 210 seconds.
Setting the maximum size of each 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 each join or prune message to reduce the impact.

Enabling IPv6 PIM to work with BFD
IPv6 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 is aged out. However, it might take a long
period of time before detecting the link failures among the PIM neighbors and starting a new DR election
process. 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.
