As Frame Relay is a NBMA network type, and PIM uses a DR election mechanism
in broadcast media, special care has to be taken depending on the scenario.
If you're using PIM sparse mode in a hub & spoke partial mesh, you can use
the command "ip pim nbma" on the hub router.
This command forces the router to replicate the multicast packets to all the
pim neighbors on each dlci.
Cisco strongly discourages the use of this command on pim dense environments
because of the amount of traffic that would be generated and some other
problems related to the leave process.
The book of Beau Williamson from Cisco Press provides detailed information
on this.
