Secondary VLAN IP address in same subnet as the primary IP - NO GO!

Secondary VLAN IP address in same subnet as the primary IP - NO GO!

Anyone have a clever way around this issue?

I am 90% migrated from an old Cisco environment. I had an issue where one of my vendors was running around setting the wrong gateway IP address on radiology equipment. To fix the issue on the Cisco stuff (many moons ago) I added that address as a secondary IP to the VLAN IP address.

Now - many years later I am trying to reproduce this on my Extreme environment but EXOS won't have it. It's telling me that my secondary IP address is in the same network as the primary IP address (which is true). But I sort of need that to work.

If anyone knows a neat trick around this - please share! šŸ™‚

Not 100% sure, but you may need to add a new virtual router in order to accomplish this. My sense is that you'd then have to do the same for your upstream network(s) too so likely not ideal in your example...
