ACI - Multiple EPGs under Same BD (IP Assigment)

[netbeginner]

ello All, 

We have scenario where Multiple EPGs are configured under same Bridge Domain(BD), would like to understand IP assignment for node ...For eg :

BD :  bd_shared_service  , BD Subnet : 10.10.10.0/24

EPG-1 :  epg_ss_10

EPG-2 :  epg_ss_20

We have configured node with VLAN10 (i.e EPG-10) and node with VLAN20(i.e. EPG-20) how the DHCP IP assigment has been done from subnet 10.10.10.0/24 because it's sharing among 02 BDs. 

Can define or reserved the IP range for EPG wise anywhere in ACI. Eg:  10.10.10.1 - 10.10.10.100  for VLAN-10(EPG-10) and 10.10.10.101 - 10.10.10.254 for VLAN-20 (EPG-20).

Do we require any additional configuration.

Hi @netbeginner 

I would suggest you to read the attached documents: https://community.cisco.com/t5/data-center-documents/technote-on-dhcp-relay-in-aci/ta-p/3161830 

From ACI perspective, there is no config which will allow you to reserve ranges for EPGs.

Best regards,

Sergiu
