Layer 3 Switching design / best practices

I was wondering if someone could shoot me some advice on Network design. More Specifically collapsed core/distribution model with Multiple Vlans ( including Voice ). For example for the attached Network diagram, I’m trying to decide best route:

  • Links between the Distro and Access layer should I have them /30 with DHCP running on the Access layer switches for computers connecting to it ( Data VLAN ). With a Voice Vlan SVI and “ip helper-address” to the core for VoIP DHCP.
  • Or have the Core be the main DHCP server for everything and set the Core SVI’s to xxx.xxx.xxx.xx1 and access layer SVI’s to xxx.xxx.xxx.xx2 and “ip helper-address” back to the .1 Core SVI.
