Check the PIM neighboring information.

If the neighboring router is not displayed, check the

following:

 

 

• Confirm that PIM is running on the interface connected to

 

 

the neighboring router using the show ipv6 pim

 

 

command with "interface" parameter specified.

 

 

• Verify the settings of the neighboring router.
