Task 1
R1 is the RP and MA in the multicast domain. Configure R1 so it allows all multicast group registration only if it sourced by 10.1.234.4. All other sources should be denied.

Solution

Task 1

R1 is the RP and MA in the multicast domain. Configure R1 so it allows all multicast group registration (multicast stream) only if it sourced by 10.1.234.4 (server). All other sources should be denied.

R1 Configuration:

!

ip access-list extended ALLOWED_SOURCES
 permit ip host 10.1.234.4 224.0.0.0 15.255.255.255
!

ip pim accept-register list ALLOWED_SOURCES

!
