My brother has an ax3 working fine off LAN port on movistar modem/router. It provides better wifi than the wifi provided by the modem router. We could leave well enough alone there, but he wants to see if most of the traffic responsibility can be hosted by the ax3. Specifically the internet and the IPTV. They are thinking of ditching the landline telephone component anyway and is not a factor since the ax3 does not have a telephone jack etc…
Reading darknate and mkx recent replies in other threads, it would seem appropriate now to try this as the MT RoS of late is helpful in this regard. The moviestar uses an older IGMPv2 standard and I note that in the settings there is IGMP snooping turned on, in the moviestar settings.
Other salient bits of information:
vlan6= internet ( although this thread is primarily about IPTV )
vlan2= iptv
THERE is no IPTV DHCP, as its a static setting with gateway.
Stuff gleaned from sources
- need one bridge for all ports where in actuality there will only be two ports being used , two WLAN ports (ports 2-4 not used at the moment)
- ether1 data going upstream will need to be tagged with vlan 6, vlan2 but untagged for all lan/wlan ports on router 2-4 (keeping ether5 for off bridge access)
- hw acceleration needs to be turned off for ether1 (bridge port setting)
- need to add a bridge filter rule to assign CoS for internet vlan of value ¨4¨ for vlan-internet-6 (output chain protocol vlan)
- need to add a bridge filter rule to assign CoS for iptv vlan of value ¨1¨ for vlan-iptv-2 (output chain protocol vlan)
- igmp snooping needs to be turned at the BRIDGE.
- igmpproxy needs to be set to version2 at the BRIDGE
-the default setting of Multicast Router as temporary query is fine.
-the Multicast querier box below this should be left unchecked, as I am assuming the modem or something upstream is the actual querier.
Any other considerations I should be thinking of??
Admission: Never have dealt with multicast, IGMP, PIM etc, so am in the blind so to speak! I am going to attempt to muddle together some sort of config, which will obviously be piss poor, but more or less where I am heading in the future. Get your knives out. 
FIrst change. After reading the MT docs…
It would appear that on the Bridge Itself, I should ENABLE multicast querier and turn OFF multicast router.
On the interface bridge port (in this case WLAN ) going to a TPLINK extender connected by ethernet cable to the iptv set top box, I make PERMANENT the multicast Router option.
Additionally I would need something like to indicate flow is coming upstream from ether1 to devices connected to the bridge. Although I may have to indicate the VLAN2 not ether1
/routing igmp-proxy interface
add interface=ether1 (or better vlan-iptv-2 ??)upstream=yes
add interface=bridge1
And this because there is only one set top box…
/routing igmp-proxy
set quick-leave=yes

As you can see at the end of the coded section I have question marks on any special routing, if required for especially IPTV traffic
Excellent article with correct menus, in terms of removing internet and IPTV from the moviestar device, but heck getting IPTV setup on Ax3 is seemingly too difficult?
https://www.redeszone.net/tutoriales/configuracion-routers/configurar-askey-rtf8115vw-movistar-bridge-puente/
Now this article points to at least an easy way to bridge the internet connection, going from many users to single user.
Basically an easy way to move the pppoe connection from the isp device to the connected device of your choice (the lan bridge on the device goes to all etherports and all IPTV and VOIP data get sent to LAN bridge untagged).

With no ill effects on IPTV or telephone. Just might give this a try and see what happens LOL. Until such time I get better answers on how to setup up MT for IPTV
