Prerequisites: CCNP level skills.

Note!
All routers are running EIGRP protocol as well as multicast routing. All interfaces have been configured as Sparse-Dense-Mode.

Topology

Task 1
The routers in the topology run multicast routing. The transit interfaces use sparse-dense-mode. In order to split the RP's load in half, configure R2 to advertise its loopback as the candidate RP for groups for groups 224.0.0.0 - 231.255.255.255. Configure R3 to advertise its loopback as the candidate RP for groups 232.0.0.0.0 - 239.255.255.255. R4 should be their Mapping Agent.

Solution

Task 1

The routers in the topology run multicast routing. The transit interfaces use sparse-dense-mode. In order to split the RP's load in half, configure R2 to advertise its loopback as the candidate RP for groups for groups 224.0.0.0 - 231.255.255.255. Configure R3 to advertise its loopback as the candidate RP for groups 232.0.0.0.0 - 239.255.255.255. R4 should be their Mapping Agent.

R2 Configuration:

!

interface Loopback0
 ip address 172.16.102.2 255.255.255.0
 ip pim sparse-dense-mode
!

access-list 1 permit 224.0.0.0 7.255.255.255

!

ip pim send-rp-announce loopback0 scope 16 group-list 1

R3 Configuration:

!

interface Loopback0
 ip address 172.16.103.3 255.255.255.0
