Topology
Pic. 1 - Topology Diagram.
Note!
Routers and switches are already configured as per the topology diagram. All devices use OSPF area 0 as their routing protocol as well as multicast routing.
IP PIM Sparse Mode has been enabled on VLANs: 14, 30, 133, 143.

Task 1
Configure R1 as the RP and BSR candidate for all multicast groups. Use the most stable interface to accomplish the task.Task 2
Ensure that R3 does not receive information about RP.
Solution
Task 1
Configure R1 as the RP and BSR candidate for all multicast groups. Use the most stable interface to accomplish the task.
R1 Configuration:
!
interface Loopback101
ip address 172.16.101.1 255.255.255.255
ip pim sparse-mode
!
ip address 172.16.101.1 255.255.255.255
ip pim sparse-mode
!
ip pim bsr-candidate Loopback101 0
ip pim rp-candidate Loopback101
ip pim rp-candidate Loopback101
!
Verification:
Pic. 2 - RP Information on R3.
Note!
Without filtering, R3 receives information about RP.
Task 2
Ensure that R3 does not receive information about RP.
S3 Configuration:
!
interface Vlan133
ip address 10.1.133.10 255.255.255.0
ip pim bsr-border
ip pim sparse-mode
ip address 10.1.133.10 255.255.255.0
ip pim bsr-border
ip pim sparse-mode
!
Verification:
Pic. 3 - RP information on R3.
The previous information about RP slowly expires. R3 loses information about RP.
