load balancing

Hello

I need assistance setting up the CRS305-1G-4S+IN to work with my ISP provided 2GB Fiber hand off. I have installed 1- 10GBase -LR SFP+ and 2-1000M RJ45 SFPs into the CSR305, this will be connected to 2- RJ-45 jacks on my router. My router side I can handle but I’ve never worked with a Mikrotek before. I was told that I would have to load balance the RJ-45 ports on the CRS305 in order to make use of the 2GB handoff. Can anyone send me the instruction on how to set this up or point me to the instructions to do so.

Thank you

Sandor
