Typically you can find an environment with HSRP where you have to fix the DR as the same that the active router:
| |
| |
R1 R2
| |
-----------------
Hsrp active 192.168.1.1 (r1)
Hsrp standby 192.168.1.2 (r2)
Pim DR --> high IP --> 192.168.1.2 --> problems
So, it's important to know witch is the DR.

Manuel.

Asunto: Re: ip pim dr-priority (Multicast)
To select one of the many PIM routers in the same broadcast domain to
response to IGMP join/leave messages.
PIM DR is also responsible to poll the existing multicast groups for
any members still interested to continue receiving the multicast
feeds.
In PIM sparse-mode, the receiver DR sends PIM join (towards RPF
neighbor) and PIM prune messages from the receiver
network toward the RP.
The source DR sends PIM register messages from the source network to the RP.
