Switch send unicast to 2 different trunk ports

Hello I have small network with Edgeswitch lite. I have several vlan, management, data, others vlan are point to point and have not problems with them. In vlan 777 I Have 2 different encoders sending to unicast direction connected to switch 1. That I see on link between switches that switch 2 send unicast as to switch 1 where are decoders and as well to others switches. Why this strange behaviour?Switches.jpg

Re: Switch send unicast to 2 different trunk ports

Just to clarify,that it recieved by port 24 of switch 2 with final destination to port 25 send as well to port 21 and 22. That it recieved from port 21 and 22 send to port 25 and as well to port 24. Port 21 and 22 connect to switch 1, where port 22 is backup link.
