Abstract
In general, techniques provide a mapping of host devices to different virtual router identifiers used to identify the source MAC address used for forwarding packets to the participating host devices. For example, a method may include receiving an Address Resolution Protocol (ARP) request for a first Internet protocol (IP) address from a host device, the first IP address comprising a virtual IP address of the virtual router. The method may also include determining a virtual router redundancy protocol (VRRP) virtual router identifier (VRID) associated with the first IP address. The method may further include generating a mapping between the host device and the determined VRID. The method may also include determining a virtual source MAC address of the virtual router based on the mapping and forwarding a second packet to the host device that specifies a virtual source MAC address for the second packet.
