Confused in wireshark? what's happening?

Question

System administration

Good afternoon, all day long I have been watching this picture:

src poppy is a microtic poppy that is used as wifi in a separate vlan, dst is 01:80:C2:00:00:00 is always the same. What kind of packets are clogging the network? I disabled rstp on the microt on the bridge, but I'm still catching these packets. Pings from the local machine in the first vlan to the control of the switch go without delay, the same goes from Mikrotik to the switch and vice versa, i.e. stp do not clog the channel, but still, why does Mikrotik send these packets to an incomprehensible poppy broadcast?

Answer 1

Apparently still not cut down STP
