Configuring Interface Priority for the PIM Designated Router Selection
By default, every PIM interface has the lowest probability (priority 0) of being selected as the DR. Configuring the interface DR priority helps ensure that changing an IP address does not alter your forwarding model.
To configure the interface DR priority:
- Configure the interface globally or in the routing instance.
This example shows the configuration for the routing instance.[edit routing-instances PIM.master protocols pim interface ge-0/0/0.0]user@host# set priority 5
- Verify the configuration by checking the Hello Option
DR Priority field in the output of the show pim neighbors
