I have 3 devices 2 raspberry pies running home assistant, and I suspect Amazon FireTV recast
are blasting my home network with multicast traffic. I did have an unmanaged switch in the middle
the home is prewired into a panel, needed something there to connect all the home lan wiring to one
switch, which then could connect to the RT-AX88u with 1 wire. I have a hunch the unmanaged switch was also a catalyst to the problem.
They have brought my network down many times,
running
/sbin/service stop_mdns
on the access point routers where these 3 devices are connected to restores my network,
but i don't like to leave that feature off, it doesn't really fix/address the issue,
Home assistant can't find some devices to automate if its left off.
I've google alot on IGMP proxy/IGMP snooping. so I finally gave in and purchased affordable managed switches
that I could turn on IGMP snooping. with the 3 suspect devices now connected to the managed switches instead.
before I setup the managed switches i had configured IGMP proxy on rt-ax88u for about a week and forgotten about it.
googling says it supposed to work with upstream interface to the ISP devices such as IPTV, which I don't have one,
i own streaming devices FireTV cube. but I didn't choose any upstream ISP profile see image below.
the Home assistants devices and Firetv recast do receive internet traffic, For Home Assistant I have special
rules setup on RT-AX88u to allow outside traffic originating at AWS to reach them the 2 home assistants, using only 1 port 443, sslh, stunnel and unique sni hostname
from freeddns.org
I suspect the Firetv Recast is also using multicast traffic to all the FireTV cubes i have setup on my lan,
just a hunch there is constant multicast traffic to create video thumbnail on fireTV cubes, and guide data as well.
with my new managed switches installed/setup, Every time i disable "Enable multicast routing/IGMP Proxy" on my RT-AX88u my network goes down.
So does a managed switch with igmp snooping need or function better with
IGMP Proxy/multicast routing turned on my main router only even the way i configured it?
Full disclover I am using on RT-AX88u LAN-> Switch Control->Bonding/ Link aggregation->Lan1+Lan2 to the managed switch Ling Aggregation 2 ports.
also have Dual Wan with Load balance using my own scripts to make sure the 2nd ISP WAN is restarted on reboots when it doesn't come up.
