Issue with PIM-SSM Multicast Configuration ISR4431s
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.
contrary to what sometimes is written in configuration guide to build a working PIM SSM internetwork you need to configure Ip pim SSm in ALL routers in the path and not only on the edge routers.
I would suggest you to add on R2:
ip pim ssm default
remove also all the commands related to transition to source based tree as there is no RP in PIM SSM the source needs to be known in advance as an IGMPv3 join describes both the group address G and the source address.
