[FROG] FRR

Hello, I found different approaches regarding the usage of GPL'ed libraries; so I would like to specifically ask regarding the usage of FRR binary. Can I link FRR binary as is with no modification to it nor its source codes to proprietary codes/binary and then sale the commercial product to customer while FRR is embedded in that product as well, or do I need to open source the product or binary that FRR is used on that. Appreciate if you may assist me with this case. Best regards, Azadeh
