CRS125 Multicast FDB question

RouterOS General
1

For some odd reason, this doesnt seem to work:
/interface ethernet switch multicast-fdb
add address=00:02:XX:XX:XX:XX bypass-vlan-filter=yes svl=yes
add address=00:02:XX:XX:XX:XY bypass-vlan-filter=yes svl=yes
add address=00:02:XX:XX:XX:XZ bypass-vlan-filter=yes svl=yesAnd CRS stills floods multicast out from every single Ethernet Interface which is in up state.

Am I missing something?

I dont use bridge interface, and I have IP configured directly on ether1, which is master port for all other switch ports.
STB`s are currently connected to ether23, ether10, ether6.
Still all that Multicast traffic is visible on every other ether interfaces aswell, which are in up state and have somekind of device connected to it… :unamused:

Make sure you have set multicast lookup mode for MAC address.

/interface ethernet switch set multicast-lookup-mode=dst-mac-and-vid-always

Thank you for the tip :smiley:
Will try it ASAP and will report back…

Unfortunately, there was an zero change, still doesnt seem to work… :frowning:

Tried by IP adress aswell, absolutely no change… :confused:

/interface ethernet switch set multicast-lookup-mode=dst-ip-and-vid-for-ipv4

Relevant config for my IPTV Setup:
/interface vlan
add interface=sfp1 l2mtu=1584 name=sfp1.4 vlan-id=4

/ip dhcp-client
add default-route-distance=0 dhcp-options=clientid,hostname disabled=no
interface=sfp1
add add-default-route=special-classless dhcp-options=clientid,hostname disabled=no
interface=sfp1.4

/ip firewall nat
add action=masquerade chain=srcnat out-interface=sfp1
add action=masquerade chain=srcnat out-interface=sfp1.4

/routing igmp-proxy
set query-interval=1m5s

/routing igmp-proxy interface
add alternative-subnets=10.0.0.0/8 interface=sfp1.4 upstream=yes
add interface=ether01ether01 is a Master Port for switch group, all other ethernet interfaces are its slaves.
sfp1 is used as an uplink to ISP.

And actually this:

dst-mac-and-vid-always

makes me wonder, maybe it doesnt work because in my case VID=0?
Still, I dont see any reason why I should use vlan`s if I actually don’t want to segment my Local Network…and according to documentation, this feature should support SVL too… :unamused:

When adding MFDB entries, you should specify destination ports with “ports=” parameter. That is missing in your posted configuration.

Tried that already yesterday, I didnt notice anything changing much, multicast still flooded out on all interfaces...

0 00:02:9B:CA:88:93 ether24 0 yes yes noneether24 is correct, I moved one STB from ether23 to ether24 and removed others from network... :wink:
