• Dual Nodes Vs Dual Routers  HA
• Active/Standby Model ( SSR are a mirror images of one another , using 2x redundancy-group )
• Active/Standby Model with Fabric Interface  ( redundancy-group configuration is no longer mandatory )
• Active/Active Model  : leverage the best ISP path, true SDWAN.   (e.g., node 1 uses ISP 1, node 2 uses ISP 2) , + Fabric interface to use both ISPs
• Hybrid Model:   some LAN/WAN are protected, some not. 

RG is per Node not accross Nodes!!!
