configure secondary ip address on Meraki L3 switch

Hi, how do you configure a secondary ip address on an interface vlan on a Meraki L3 switch? WE have a superscope on a cisco network. With other words we have two /24 subnets on vlan 1. THe vlan 1 interface is configured with a primary and secondary ip address. Now we want to bring in a Meraki L3 switch to the routing in exactly the same way. Help is appreciated. Thanks.

Secondary addresses are not available on Meraki devices.

Anything I can do to get around this issue so that I'll have 2 ip addresses as gateway for 2 subnets in one vlan?

I think I'm obliged to say "Don't use Multinets!" here. It's not really a good practice other than for transition...

 

You could create a second L3 interface on a different VLAN, and the bridge those VLANs together with two back-to-back access ports. This would create a VLAN Hopping situation so your second subnet would be served by the SVI of another VLAN. But that's also bad practice...

I agree but that was already done and we cannot quickly remediate this issue. 

 

And I honestly don't like that solution either because we have more vlans on that network that are not super scoped.

I hear you. I'm not trying to be all preachy at you. But for anyone else that reads this at some later date in the future I think it's good to just state that.
