LACP between Riverstone RS8000 and Cisco ASX9000

This is my first post to Nanog. I apologize if it is off-topic but I have been driving myself crazy trying to figure this out.

Is anyone familiar with configuring LACP between Riverstone RS8000 (Running ROS and a Cisco ASX9000.
I am attempting to bring in 2 Gigabit Fiber links from NTT and bond them using LACP we will be using these links for a full BGP feed.

Any help would be appreciated, replies on or off list are alright with me.
