Hi, if disable user-bridging in one VLAN on OLT and ONT, then the broadcast and multicast traffic will also be blocked for the other clients, only core switch (upstream devices) will receive the broadcast (like arp) and multicast traffic, right? Please advise, thanks.

No. Disabling the Layer 2 bridging function of the VLAN can prevent broadcast domains. It is not directly related to multicast. The access agent configured on the core switch can communicate with each other.
