Abstract
Techniques are presented to signal where a virtual machine (host) has moved in a data center networking environment. These techniques use Multiprotocol Border Gateway Protocol (MP BGP) alone, and are particularly useful in a multi-vendor environment using existing standards. Reverse Address Resolution Protocol (RARP) broadcast is not needed, therefore, no L2 extension is needed across a data center interface for tenants that do not require L2 extension for purposes other than a host move. This scheme works for both inter- and intra-fabric moves.
