Hi experts
Thanks for your replay

R1-------R2-----R3-----R4------R5

R2 is highest lo0 than R4,

the question is

Enable spare-mode on R1, R2,R3,R4 and R5
most reliable interface of R4 must be RP for 227.39.39.39 and 228.39.39.39
R2 must be backup RP for R4. use lo0 for this. Don't create additional
loopbacks
Dont alter any ip address. Don't configure static RP

R4
ip pim bsr-candidate Loopback0 0
ip pim rp-candidate Loopback0 group-list 20 priority 50

R2
ip pim bsr-candidate Loopback0 0
ip pim rp-candidate Loopback0 group-list 20 priority 100

Is this soluation correct? can anyone correct me....

Regards
