Guys

 

I have this topology

 

 

R3 S1/0------------------R5-----------R4-Fa0/1------ip igmp join-group
228.28.28.28

       ------------------R1

 

R3 have multipoint interface , with frame-relay, I hope my drawing could be
understand,

 

Multicast we all do with Sparse mode with R5 as the auto-rp mapping agent
and the auto-rp

 

So, I have to test connectivity from r1, I have Ip pim nbma mode int the
interface s1/0 of R3.

 

But The R1 still cannot ping to R4 group 228.28.28.28.

 

So after confusion, I tried this command on r3s1/0 "ip pim dr-priority 200"
(my friend told me)

 

and IT WORKS.

 

So what is ip pim DR-priority 200 means ? Why is this solution never come in
IEWB Workbooks (AS FAR As I know, sorry if this solution actually appear in
IEWB WOrkbooks, please give me the lab number, I want to learn more.)

 

Please help Guys

 

Thanks
