Abstract: A multi-chassis link aggregation (MC-LAG) system includes one or more dual homed nodes coupled to a pair of switches (MC pair) and one or more single homed nodes coupled to a single one of the MC pair of switches. The MC pair of switches advertises a virtual IP address for the dual homed nodes such that traffic may be received at either switch in the MC pair for the dual homed nodes. For a single homed node, a dedicated IP address is advertised associated with a switch in the MC pair locally connected to the single homed node. Traffic destined to the single homed node is thus transmitted to the switch in the MC pair locally connected to the single homed node.

Abstract: Various embodiments relate to a method, device, and machine-readable storage medium including: exchanging messages between a virtual machine and the overlay network; identifying a request message transmitted by a virtual machine supported by the server as requesting an underlay resource that is inaccessible via the overlay network; sending a proxy request to the underlay resource via the underlay network; receiving, at the server, at least one message from the underlay resource in response to the proxy request; and forwarding the at least one message to the virtual machine based on determining that the virtual machine previously requested the underlay resource.
