- Allocate one ip from each subnet of a VN for each PR.
- Persist the ip and the association with VN, Subnet, PR in cassandra DB
- On DM restart, read the DB state and maintain allocated ip map in local memory
- On update/restart, find differences between allocated
ip map vs VNC DB state of VN, and take necessary actions
- GW IP of the subnet is configured on the MX as the
virtual-gateway-address under the IRB IP address
