We're seeing GB WAN offerings ramping up in our rural area and I am struggling with the limitations of the small business applicable MX appliances and their inability to support that much bandwidth. Does anyone know or heard if this is something Meraki is working on or has plans to address? Or, is there some backdoor option vlan work around to use an LAN GB port for WAN traffic?
I also think that the CPU power might need increasing, we have a site with HA MX84s and 80Mb of streaming video over the SD-WAN keeps the CPUs at 50% load. Therefore the MX84s look to at most be able to manage 150Mbps of SD-WAN traffic unless it isn't linear.
@Red-Five id imagine it it more likely that the base speed might get nearer 1Gbps but it will reduce with all features enabled, as I mentioned elsewhere an MX84 has a base throughput of 500Mbps, VPN throughout of 250Mbps, but I'd estimate the CPU becoming pretty loaded at 150Mbps of SD-WAN throughput, based on 80Mbps using 50% CPU.
Are you in the position you actually need a sustained 1GB of WAN traffic
There is also no law that says that site-2-site traffic has to use the same appliance than internet/guest internet traffic.
You could very well have your core switching have internal routes pointing towards SD-WAN MX appliances (enterprise license) and have internet traffic pointing towards another pair of MX'es (different org with advanced license).
I know it is expensive but having a 1 GB link is an investment.
