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?
