- When Next is clicked, the lab closes and cannot be reopened.
Topology
Tasks
R2 and R3 are routers that perform multicast operations. Candidates are required to perform the below configuration and verification tasks on R1 and R2.
1. Configure R2 and R3 to be able to process, route and forward multicast packets.
2. Configure R3 as the root of the shared tree for the any source multicast domain.
3. Configure R1 as the receiver for group 239.100.100.1 and ensure a ping to that group from R4 is successful.
Initial configuration with IP addressing has been completed. The candidate must not make any changes to the configurations except to fulfill the tasks listed above. Use non-proprietary protocol where needed. Only use the provided logical interface for the applicable task.

1. Configure R2 and R3 to be able to process, route and forward multicast packets.
2. Configure R3 as the root of the shared tree for the any source multicast domain.
3. Configure R1 as the receiver for group 239.100.100.1 and ensure a ping to that group from R4 is successful.

Correct Answer:
1. Enable Multicast Routing on R2 and R3
To process, route, and forward multicast packets, multicast routing must be enabled globally, and PIM (Protocol Independent Multicast) must be configured on the appropriate interfaces.
Commands on R2 and R3:
R2(config)# ip multicast-routing
R2(config)# interface e0/0
R2(config-if)# ip pim sparse-mode
R2(config)# interface e0/1
R2(config-if)# ip pim sparse-mode
R2(config)# interface loopback 0
R2(config-if)# ip pim sparse-mode
R3(config)# ip multicast-routing
R3(config)# interface e0/0
R3(config-if)# ip pim sparse-mode
R3(config)# interface e0/1
R3(config-if)# ip pim sparse-mode
R3(config)# interface loopback 0
R3(config-if)# ip pim sparse-mode
ip multicast-routing enables multicast routing globally.
ip pim sparse-mode enables PIM in Sparse Mode on interfaces.
2. Configure R3 as the Root of the Shared Tree (Rendezvous Point - RP)
To configure R3 as the RP for the multicast domain, use Auto-RP or Static RP. Here, we configure Static RP for group 239.100.100.1.
Commands on R2 and R3:
R2(config)# ip pim rp-address 3.3.3.3
R3(config)# ip pim rp-address 3.3.3.3
ip pim rp-address <RP-IP>: Configures R3's Loopback0 IP (3.3.3.3) as the RP for the multicast domain.
3. Configure R1 as the Receiver for Group 239.100.100.1
To configure R1 as a multicast receiver, enable IGMP (Internet Group Management Protocol) on R1's e0/0 interface.
Commands on R1:
R1(config)# interface e0/0
R1(config-if)# ip igmp join-group 239.100.100.1
ip igmp join-group <group>: Forces R1 to join the multicast group 239.100.100.1.
Verification: Ensure Ping to Group 239.100.100.1 is Successful from R4
To verify multicast group reachability:
1. Send Multicast Traffic from R4:
R4# ping 239.100.100.1 repeat 5
2. Verify Multicast Routing Table on R2 and R3:
R2# show ip mroute
R3# show ip mroute
3. Verify IGMP Group Membership on R1:
R1# show ip igmp groups
Complete Summary of Configurations:
1. R2 Configuration:
ip multicast-routing
interface e0/0
ip pim sparse-mode
interface e0/1
ip pim sparse-mode
interface loopback 0
ip pim sparse-mode
ip pim rp-address 3.3.3.3
2. R3 Configuration:
ip multicast-routing
interface e0/0
ip pim sparse-mode
interface e0/1
ip pim sparse-mode
interface loopback 0
ip pim sparse-mode
ip pim rp-address 3.3.3.3
3. R1 Configuration:
interface e0/0
ip igmp join-group 239.100.100.1
Verification Checklist:
1. R3 is the RP: Use show ip pim rp mapping..
2. R1 is a Group Member: Verify with show ip igmp groups.
3. Multicast Traffic Flows: Use ping 239.100.100.1 from R4 and verify success.
To process, route, and forward multicast packets, multicast routing must be enabled globally, and PIM (Protocol Independent Multicast) must be configured on the appropriate interfaces.
Commands on R2 and R3:
R2(config)# ip multicast-routing
R2(config)# interface e0/0
R2(config-if)# ip pim sparse-mode
R2(config)# interface e0/1
R2(config-if)# ip pim sparse-mode
R2(config)# interface loopback 0
R2(config-if)# ip pim sparse-mode
R3(config)# ip multicast-routing
R3(config)# interface e0/0
R3(config-if)# ip pim sparse-mode
R3(config)# interface e0/1
R3(config-if)# ip pim sparse-mode
R3(config)# interface loopback 0
R3(config-if)# ip pim sparse-mode
ip multicast-routing enables multicast routing globally.
ip pim sparse-mode enables PIM in Sparse Mode on interfaces.
2. Configure R3 as the Root of the Shared Tree (Rendezvous Point - RP)
To configure R3 as the RP for the multicast domain, use Auto-RP or Static RP. Here, we configure Static RP for group 239.100.100.1.

3. Configure R1 as the Receiver for Group 239.100.100.1
To configure R1 as a multicast receiver, enable IGMP (Internet Group Management Protocol) on R1's e0/0 interface.
Commands on R1:
R1(config)# interface e0/0
R1(config-if)# ip igmp join-group 239.100.100.1
