Each EPG will need a bridge domain, but they can share the same VRF.

How to do it...

  1. We will create two bridge domains (Finance-BD and Marketing-BD); they will use the same VRF we created a moment ago, and we will enable ARP flooding and layer-2 unknown unicast flooding, which is required when using an ASA in GoTo mode:
      apic1(config-tenant)# bridge-domain Finance-BD
      apic1(config-tenant-bd)# arp flooding
      apic1(config-tenant-bd)# l2-unknown-unicast flood
      apic1(config-tenant-bd)# vrf member ACME-VRF
      apic1(config-tenant-bd)# exit
      apic1(config-tenant)# bridge-domain Marketing-BD
      apic1(config-tenant-bd)# arp flooding
      apic1(config-tenant-bd)# l2-unknown-unicast flood
      apic1(config-tenant-bd)# vrf member ACME-VRF
      apic1(config-tenant-bd)# exit
      apic1(config-tenant)# 

How it works...

The bridge domains have been created with the flooding options and are members of the VRF (Tenants | ACMECorp | Networking | Bridge...
