vMX100 on Azure, configured as HUB

Hello all,

 

Can vMX100 be configured as HUB in Azure? 

The network will have north of 100 spokes eventually.

 

If this is possible, can you share reference architecture?

If it is not possible or not advisable, can you share the reasoning behind this?

I have clients with hundreds of spokes, and that has never been a limitation.

 

However you can deploy dual VMX appliances and run them active/active.  You typically use a pair of templates, and make half the sites use one VMX and half use the other.

It can only operates in VPN concentrator mode in Azure.  Consequently running in hub mode is the most common deployment.  You could also deploy it as a spoke of another hub, but this configuration would not be common.

 

This is the Azure deployment guide:

Thanks. How do you overcome the 500mbps throughput limitation?

Another special note.

 

I don't know why, but a small percentage of the deployments I do into Azure have permanent 5% packet loss over AutoVPN.  So when I stand up the VMX in Azure I connect a spoke up ASAP, and leave a ping running to a server in Azure for an hour (interestingly if you leave the ping running to the VMX there is zero packet loss).

If you experience the packet loss the only solution is to delete the VMX and re-deploy it.  There is no other fix.
