I have an interesting issue that I inherited via a consultant who was not well versed on the system he was working on. I have to route multicast traffic to different vlans from the source vlan. The source of the multicast is in network 172.25.135.0/25, however the end devices are located as follows:
There are no routers in use only Cisco 9300 series. Without a router acting as a querier, I would have to enable multicast routing on each switch, enable igmp snooping on each vlan, and PIM on each vlan interface:
ip multicast-routing (global config each switch)
interface vlan XX (interface config for each vlan wanting to receive multicast traffic)
ip igmp snooping ip pim sparse-dense-mode
I would prefer to move this all to one vlan and re-ip the devices to make it easier, but alas!!
