Can anyone help me in how to decide the multicast scope. Putting it in simple way I have 4 Routers R1--R2--R3--R4. R1 is configured as RP and I need to configure scope in such a way that Multicasting doesnot forward after R4.
Whether I have to configure R1 with scope as 3 (with calculation of R2,R3 & R4 as 3 Hops) or scope as 4 (with calculation of R1,R2,R3 & R4 as 4 Hops)
Thanks in advance,
