Solution

Task 1
R1 is the RP and MA in the multicast domain. Ensure that R1 does not become RP and MA beyond the domain pictured in the topology diagram (pic. 1).

R1 Configuration:
!
ip pim send-rp-announce Loopback0 scope 2
ip pim send-rp-discovery Loopback0 scope 2
!

Note!
By limiting the TTL of the RP/MA announcements to two hops, routers beyond R6 and R4 will not receive the these messages.
