Prioritize Router Messaging With PIM DR-Priority

This example specifies that messaging is received by VLAN 5 every 10 seconds.

1. Enable PIM globally.

   SEFOS# configure terminal
   SEFOS(config)# set ip pim enable
   

2. Enter Interface Configuration mode for the interface.

   SEFOS(config)# interface vlan 5
   

3. Associate the VLAN interface with the PIM component.

   SEFOS(config-if)# ip pim componentId 1
   

4. Specify how often (in seconds) the switch sends PIM messages to the interface.

   SEFOS(config-if)# ip pim query-interval 60
   

5. Specify how often (in seconds) the router receives messages.

   SEFOS# ip pim dr-priority 10
   SEFOS(config-if)# end
   

6. Ensure that the correct router messaging time period has been set.

   SEFOS# show ip pim interface detail
