EXTEND VLAN on Legacy Switch

[workmen]

HI Guys, 

 Just want to confirm if creating an SVI to an extended legacy switch [3850] would cause VLAN conflict with a Meraki VLAN. Say, I create VLAN 50 on Meraki MX then I connect a 3850 with SVI 50?

Thanks

I would just have to ask why?

Just as long as the SVI L3 interface IPs aren’t the same then you shouldn’t have an issue.

That is fine.  It will be VLAN50 on both devices, carrying the same layer 2 traffic.
