Let's say that I have toplogy where two VDX 6720-60 are connected using 3x10GE ports.
Will this 3 x 10GE ports act as one Layer 2 route path for TRILL of 3 equal Layer 2 paths and then VDX will do ECMP load-balacing to load-share traffic over all 3 10GE ports.
Another question - is it maximum links for single ISL is limited ? As I know ISL have to be in one port group. So It mean that I can have 10 ports for 6720-60 switches and 12 ports for 6720-24 switches.

Here are links to blogs that explain how VCS Fabric ISLs form, how Brocade ISL Trunks form and how all that works with ECMP at layer 2. I hope this is helpful.
