Hit router interface limit
Hello,
We are at a stage where we need to add more client environments.
However the existing pair of internet facing VM (vyos) routers are at maximum capacity for ethernet interfaces, due to VMware only being able to allocate 10 interfaces per VM.
Currently each ethernet interface is dedicated to a client environment on each subnet there is a maximum of 12 IPs being used.
router1 and router2 external facing BGP
router3 and router4 internal OSPF
An ethernet interface has been added for each client subnet on all routers.
What are the options available to scale out more environments?

Please see attached pic, we already have a PCI device. By adding more on router 1 and router 2 will that get us around this issue if the limit is only 10 interfaces for a VM?

Maximum virtual interfaces is 10.
PCI devices are not virtual interfaces they are physical.
Maximum number of PCI devices is 16.
So theoretical maximum of network devices (interfaces) 10 virtual and 16 physical.
26 per VM, how many do you need ?

If I was to add another 10 environments would I need a PCI for each client network?
Please see attached pic of router3 VM.

Use more VMs, wait for a newer version of VMware vSphere which supports more than 10 virtual network interfaces.
