Abstract
Described herein are systems and methods for host multihoming with no state synchronization between top-of-rack (ToR) switches coupled to multiple hosts. ToR switches of a multi-homing system share a virtual MAC address and respond to Address Resolution Protocol (ARP) requests and/or Neighbor Discovery (ND) solicitations for a default gateway IP address from the host with the virtual MAC address. Ports on a ToR switch may be configured either with a static ARP and/or ND entry, or be configured to learn via a discovery protocol. The lightweight host multihoming system may have modified flooding behavior, ARP/ND handling, and data path forwarding. ARP/ND traffic from a host is processed by a ToR switch, while other multicast traffic may be discarded. Embodiments of the host multihoming system provide a lightweight solution for software implementation with minimal changes imposed on the host or network design.
