@raminmalek,
normally, SPAN means that you obtain a copy of particular actual traffic (passing through a particular port or group of ports, or within a VLAN). In Mikrotik, this is usually called traffic mirroring. What you describe (bridging EoIP tunnel and Ethernet interface together) doesn't seem to be related to traffic mirroring, except if you have a mirror destination Ethernet port on some equipment, and you connect the Ethernet port bridged with the EoIP tunnel to that port using a patchcord. So first of all, provide a diagram showing the device(s) involved, the flow of the actual traffic, and the expected flow of the mirrored traffic. Also the other end of the EoIP tunnel needs to be shown on the diagram, especially if it is a CHR.

Post an anonymized export of the configuration of the router where this happens.

add bridge=UDR-Brid broadcast-flood=no hw=no interface=ether1-UDR-Brid \
unknown-multicast-flood=no unknown-unicast-flood=no
add bridge=UDR-Brid broadcast-flood=no interface=Tunnel-UDR-Brid \
unknown-multicast-flood=no unknown-unicast-flood=no

If the traffic that arrives via the EoIP tunnel is a copy of some source traffic (which is what mentioning SPAN in the topic title suggests), the destination MAC addresses of that traffic are not those of the device(s) connected to ether1-UDR-Brid. Therefore, setting broadcast-flood, unknown-unicast-flood, and unknown-multicast-flood on the /interface bridge port row for ether1-UDR-Brid to no prevents the bridge from egressing that traffic via this port. See https://wiki.mikrotik.com/wiki/Manual:I ... t_Settings for details.
