- 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 InterfaceInterface (
redundancy-group
configuration is no longer mandatory ) - Active/Active ModeModel : 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!!!
