Hi all,
I'm currently having problem to converting multicast to broadcast using the "ip multicast helper-map" feature.
i'm using 2 ISR4331 routers, the IOS version on both is: 17.03.5. With APPX package.
I just want to mention that the same configuration worked on cisco 2951 routers, with IOS 15.7.
We have an application that the communication between the nodes based on broadcast massages.
At router A, the sent broadcast is converted to multicast, but on router B, the multicast doesn't converted back to broadcast.
Router A configuration:
interface GigabitEthernet0/0/0.41
encapsulation dot1Q 41
ip address 192.20.201.116 255.255.255.248
ip multicast helper-map broadcast 239.192.201.116 SSS
ip pim sparse-mode
standby 41 ip 192.20.201.113
standby 41 priority 120
standby 41 preempt

The GRE is needed because of non multicast routing WAN, and i have also tried to move the "ip multicast helper-map" to a subinterface/ phisical interface/ loppback interface, and non was working.
any ideas where i'm getting it wrong?
Thanks
Dima
