Section 9: Multicast (4 Points)
Enable your network to allow hosts on VLAN4 to receive and send multicast traffic from and to VLAN2; only perform configuration on R5 and R6 using PIM sparse dense mode.
Configure R6 to respond to pings from R5 to the multicast address of 224.4.4.4.
Do not allow R5 to fully participate in the PIM process by not allowing it to become a neighbor, but do allow any IGMP messages generated by hosts on VLAN4 to be received by R6.
