Cisco ACI - Can ping gateway (BD) but not endpoints

 I can ping the gateway from a switch connected through L3Out (ospf) but not the VMs. I see the VM IPs under operational tab of the EPG and they are being learned. I see all the routes being learned through OSPF on the L3Out. Also I can see the ospf external -2 route for the network from the exernal L3 Switch.

 

Is there anywhere on the L3Out config I need to 'allow' this network to be advertised outside the fabric? Just checking 'advertise externally' and associating to adding) the L3Out under the BD config should be enough correct?

Are the EPGs and L3out in same VRF?

Do you have contracts setup for the EPG and the L3out?

From the leaf where you learn the VMs, are you able to ping them?

Under L3out are you allowing the subnets you want into ACI? Alternately you can use 0.0.0.0/0
