Hello,
I have configured 2 IPNs and POD2 on ACI with tep pool 10.1.0.0/16
OSPF between spine and IPN is up
I can see the pod2 spine in the discovered fabric however, its status is stuck at discovering and no infa IP is assigned to it.

Hi,
I am not using any authentication and no public keys on APIC. I have also erased the config of the remote spine and leaf but still the same issue.

Hi @e-chuah,
One reason that the APIC is not replying with the DHCP Offer is that the Spines' uplinks of the 2nd Pod are not already configured as part of the infra L3Out. This L3Out is the one you'll find in Tenant Infra and you should have in advance the Spines of your 2nd Pod (and subsequent Pods in the Multi-Pod architecture) there under Configured Nodes and the respective interfaces facing the IPN configuration under Logical Interface Profiles, etc.
Also, make sure you have all related Fabric Access Policies in place and of course the 2nd Pod's TEP pool in Fabric > Inventory > Pod Fabric Setup Policy.
One good source of hits to troubleshoot ACI is Troubleshooting Cisco Application Centric Infrastructure, 2nd Edition
Hope this helps.

Hi Ziad
Was the problem solved?
If not, you can set up again Multi Pod, erase all configs and TEP Pool for Pod 2.
Erase all configuration from your Spine 201 and Leaf X with setup-clean-config. Before check if the version of your devices are the same.
Check IPs for your IPN connection, and check if your IPN devices support:
When you set up IPN make sure that you configure Rendezvous Point Address on IP PIM command and the IP for Multicast that you configure should be the same that you configured on the APIC initialization.
The IPN interfaces that connect directly with SPINE should be sub-interfaces with VLAN 4 encapsulation, also verify MTU.
You need two pools when you are configuring Multi Pod, 1 pool for EXTERNAL TEP on Pod 1 (this pool should be between /22 - /27 prefix mask) an other pool for External TEP for Pod 2.
You should use the set up wizard for configure Multi Pod is a great guide.
