Proactive convergence of endpoint reachability in data centers

A system comprising:

• one or more processors;
• and
• one or more computer-readable media storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• determining that a virtual machine (VM) is moved from a first location to a second location, the first location being associated with a first switch of a plurality of switches within a network, and the second location being associated with a second switch of the plurality of switches;
• prior to a move of the VM from the first location to the second location being completed, receiving, at the second switch, a message comprising a MAC address and one or more IP addresses associated with the VM, wherein the message is sent from the first switch;
• storing, at the second switch, the MAC address associated with the VM and the one or more IP addresses associated with the VM;
• and
• advertising, by the second switch and to the plurality of switches, reachability information of the VM, the reachability information comprising one or more IP-MAC bindings, the reachability information being advertised prior to the move of the VM being completed.

One or more non-transitory computer-readable media storing computer-readable instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• determining that a virtual machine (VM) is moved from a first location to a second location, the first location being associated with a first switch of a plurality of switches within a network, and the second location being associated with a second switch of the plurality of switches;
• prior to a move of the VM from the first location to the second location being completed, receiving, at the second switch, a message comprising a MAC address and one or more IP addresses associated with the VM, wherein the message is sent from the first switch;
• storing, at the second switch, the MAC address associated with the VM and the one or more IP addresses associated with the VM;
• and
• advertising, by the second switch and to the plurality of switches, reachability information of the VM, the reachability information comprising one or more IP-MAC bindings, the reachability information being advertised prior to the move of the VM being completed.
