I have an issue with my PIM-SSM multicast configuration using ISR4431s.
I am wanting to forward broadcast data from an application from one VLAN in on the multicast source to another VLAN on a multicast router on a small network. The method I am using is PIM-SSM. I have a multicast source R1, a multicast transition router R2, and a multicast receiver, the R3 device.
Any insight into why the broadcast data is not forwarding is welcome.
Here is the topology:
R1---R2---R3
R1 R2 R3
vlan 100 (IP: 10.1.1.1)--10.194.234.226-|--G0/0/0 (IP: 10.194.234.225)---G0/0/0 (IP: 10.156.51.225)-|-G0/0/0 IP: (10.156.51.226)--vlan 600 (IP: 192.142.1.1)
