Fixed In Version: opendaylight-8.3.0-1.el7ost
Doc Type: Known Issue
Doc Text:
Layer 3 connectivity between nova instances across multiple subnets may fail when an instance without a floating IP tries to reach another instance that has a floating IP on another router. This occurs when nova instances are spread across multiple compute nodes. There is no suitable workaround for this issue.
