Prerequisites: CCNP level skills.

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 pim bsr-candidate Loopback101 0
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

!

Verification:

Pic. 3 - RP information on R3.

The previous information about RP slowly expires. R3 loses information about RP.
