Transit/Management VLAN Question

Heya,

Was wondering if anyone has advice for implementing transit VLANS.

Currently, we have a setup where each site has a L3 head switch and then has static routes back to our distro switch.

I am wanting to validate that best practices have the transit VLAN between the L3 Switch and Distro Switch look something like 192.168.1.0/30, giving me just the 2 usable in that network. To clarify the L3 Switch and Distro would share the Transit and the Management VLAN built out on the L3 Switch side would point to the transit for all traffic leaving the site?(as well as any other VLAN built out on the L3 Switch) ---- Please validate or correct ---

​

If you give examples it helps my brain!

Thanks in advance!
