Re: [c-nsp] fabricpath and vPC+
Use port channels. In a FabricPath topology, loop-free trees are created to forward multidestination frames (broadcast, multicast, etc.). If you use individual links between switches, only one of those links will be a part of the tree. If you use port channels, the entire port channel will be used. Additionally, though I doubt it matters in most deployments, with port channels you'll have 2-16x fewer ISIS adjacencies (reduced CPU utilization).

PL & PKA are required in VPC+ just like in VPC. If you don't need VPC+, then yes you could just do parallel FP links and use ECMP for load sharing instead of port-channel, it's your choice.
