Enabling PIM on an Interface
You can enable PIM on an interface in one of the allowed modes and specify how often
the interface sends hello messages to neighbors.
You can configure PIM and MLD on the same interface. If you configure MLD and PIM on
an interface, the router considers that PIM owns the interface.
ipv6 pim query-interval
• Use to specify how often the router sends hello messages to neighbors.
• Example
host1(config-if)#ipv6 pim query-interval
• Use the no version to restore the default setting, 30 seconds.
• See ipv6 pim query-interval.
ipv6 pim sparse-mode
• Use to enable PIM in sparse mode on an interface.
• Example
host1(config-if)#ipv6 pim sparse-mode
• Use the no version to disable PIM in sparse mode on an interface.
• See ipv6 pim sparse-mode.
ipv6 pim sparse-mode graceful-restart-duration
• Use to set the graceful restart duration for PIM sparse mode.
• Example
host1(config-if)#ipv6 pim sparse-mode graceful-restart-duration 10
• Use the no version to return to the default duration of 30 seconds.
• See ipv6 pim sparse-mode.
Setting a Priority to Determine the Designated Router
You can influence whether a particular router is selected as the designated router with
the ipv6 pim dr-priority command. A higher priority value increases the likelihood that a
router is selected as the designated router, while a lower value decreases the likelihood.
The ipv6 pim dr-priority command in Router Configuration mode sets the designated
router priority on all the PIM interfaces on the router. To override this global setting on a
particular interface, use the ipv6 pim dr-priority command in Interface Configuration
mode.
NOTE: You cannot configure the designated router priority on PIM DM interfaces.
