Task 1
Based on the previous lab (Lab 151), R1 is the RP and MA (Mapping Agent) for all groups. As per your boss request, you must configure R2 and R3 so that routers should register (*, G) entries only for the group 224.40.40.40 and can be destined for 172.16.101.1 (RP).This group cannot be registered with any other RP.

Task 1

Based on the previous lab (Lab 151), R1 is the RP and MA (Mapping Agent) for all groups. As per your boss request, you must configure R2 and R3 so that routers should register (*, G) entries only for the group 224.40.40.40 and can be destined for 172.16.101.1 (RP). This group cannot be registered with any other RP.

R2 Configuration:

!

access-list 10 permit 224.40.40.40

!

ip pim accept-rp 172.16.101.1 10

!

R3 Configuration:

!

access-list 10 permit 224.40.40.40

!

ip pim accept-rp 172.16.101.1 10

!

Verification:

Pic. 2 - Another Group Registration.

After R4 have joined the 224.64.64.64, R1 (RP) does not have the group registered. It has been pruned on R2 (PIM DR).

Pic. 3 - R2 (PIM DR) Prunes the Join Message.

R2 does not build the 'register message' and the group has not been registered with RP.
