I believe I need to setup an igmp proxy and need a little help. I found this document http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3850/software/release/3se/multicast/configuration_guide/b_mc_3se_3850_cg/b_mc_3se_3850_cg_chapter_0101.pdf
but I'm a little confused and need help.
Consider the following scenario
I have vlan 100 with an IP address on it and pim dense-mode set.
I have vlan 110 with no IP address and no routing to it (no ip on vlan, no static routes).
The switch is a 3850.
Right now I have a pfsense vm with an interface in both vlan 100 and 110 acting as my way into vlan 110 (1-to-1 nat basically). Because vlan 110 has no IP address defined in the switch, snooping would not work and multicast traffic was flooding within that vlan. I found the igmp proxy option in pfsense, turned it on and the flooding stopped. On the switch, when I run show ip igmp snooping querier, I see that vlan in the list and the port of the host the vm is on. (Previously that vlan wasn't in the list as expected)
My problem is pfsense will be replaced with something else that cannot do the proxy so I figured I would have the 3850 do it directly. In this new setup, there will be static routes pointing to the IP of the new device (say 10.0.10.1) and this device will send the packets to the correct destination in the appropriate vlan.
I'm not sure if I need everything in the example from the PDF or even what my uplink/downlink is. Can someone help with the config?
Thanks
