1. Configure all routers in the topology to run PIM-SM on all links between the routers. 

2. Configure router R3 Loopback0 interface to be the RP.

3. Statically configure the RP information on all routers in the topology. 

4. All receivers use IGMPv2. 

5. On VLAN 10, router R7 should be sending the IGMP query every 10 seconds. 

6. On VLAN 10, router R6 should be handling the multicast source registration with the RP for multicast traffic originated on the segment. 

7. On VLAN 34, IGMP group should be removed after 60 seconds of inactivity. 

8. For multicast traffic originated from router R1, PIM Register message should be sent by router R1.

Highlight the text below to reveal the solution.

This task requires basic understanding of PIM-SM and IGMP configuration.

Requirement #4 - note IOS-XR using IGMPv3 by default.
Requirement #5 - IGMPv2 Querier is the router with lowest IP address on the segment. R7 host address need to be changed to be numerically lower than 6 to be elected querier. Adjust the IGMP query interval to 10 seconds.
Requirement #6 - adjust PIM priority for router R6 to win the DR election on the segment.
Requirement #7 - Adjust the IGMP query interval to 20 seconds. Timeout is 3 times the query interval.
Requirement #8 - adjust PIM priority for router R1 to wen the DR election.
