The system view is displayed.
2. Run:
interface interface-type interface-number
The interface view is displayed.
3. Run:
pim ipv6 hello-option dr-priority priority-value
The priority for the DR election is configured.
On the shared network segment where all PIM-IPv6 switchs support the DR priority,
the switch interface with highest priority acts as the DR. In the case of the same
priority, the switch interface with the highest IP address acts as the DR. If a minimum
of one PIM-IPv6 switch does not support the DR priority, the switch interface with
the highest IP address acts as the DR.
4. Run:
pim ipv6 timer dr-switch-delay interval
The DR switching delay is configured and the value of the delay is set.
When an interface changes from a DR to a non-DR, the existing routing entries are
valid until the maximum delay expires.

13.6.4 Enabling the Function of Tracking a Downstream Neighbor
When the Generation ID option in the Hello message received from an upstream neighbor
changes, it indicates that the status of the upstream neighbor changes. Therefore, you can
configure a PIM interface to deny the Hello messages without Generation ID options to obtain
the upstream neighbor status in real time.
Context
Do as follows on the switch running IPv6 PIM-SM:
NOTE
The configuration involves the following cases:
l Global configuration: It is valid on all the interfaces.
l Configuration on an interface: The configuration on an interface takes precedence over the global
configuration. If the configuration on an interface is not done, the global configuration is used.
Procedure
