Abstract
Methods, computer program products, and systems are presented. The methods include, for instance: providing a distributed virtual gateway for Network Virtualization over Layer 3 (NVO3) network. A gateway stack having three or more nodes is implemented as a distributed virtual gateway, providing Layer 2 or Layer 3 gateway services in a fail-safe manner. Nodes of the gateway stack are configured to autonomously process and forward inbound NVO3 data packets with known destination addresses without engaging a master of the gateway stack.
