Currently I have dual diverse fibres to the building each to a router with a /29 subnet on presented on ports 1 & another /29 subnet on port2. in an Active / Active configuration.
All 4 ports connect to a layer 2 switch and from this switch is connected the primary MX85 with WAN ports 1 & 2 configured the same as the router ports in load balance mode.
The MX85 is connected to the switch stack via two LAN ports
I want to add a warm spare MX85 to this network, and would use the MX Uplink IP method. My ISP is adding a third /29 subnet on Port 3 of the routers, and documentation suggests I can configure WAN1 of the warm spare to this subnet. (Gamma share all 3 subnets across the two fibres)
Have I understood this right and is this the correct configuration?
