A solution for virtual router redundancy for server virtualization includes, at a network device configured as a backup router of a virtual router, examining a packet stored in a memory of the network device. Responsive to the examining, the network device determines whether to forward the packet via a network towards a destination or to send the packet via the network to a master router of the virtual router for forwarding of the packet, by the master router, towards the destination.

Virtual router redundancy for server virtualization

Techniques that offer enhanced diversity in the selection of paths (e.g., ECMP paths) and/or ports from ports associated with trunks for forwarding network data traffic. In one embodiment, a network device uses a rotate function to generate a rotated index (path index) that is used to select a path (e.g., an ECMP) path from multiple paths (e.g., multiple ECMP paths) for forwarding a packet. A network device may also generate a rotated index (trunk index) that is used to select an output port from multiple output ports associated with a trunk for forwarding the packet.
