Dynamic instantiation of remote virtual extensible local area network tunnel end points acquired through a control protocol

摘要

A method is provided in one example embodiment and includes acquiring at a local network element information regarding a remote network element via a control protocol distribution method and refraining from instantiating the remote VTEP for the remote network element on the local network element until unicast traffic from the local network element to the remote network element via an overlay network has begun. The method may further include detecting unicast traffic from the local network element to the remote network element and subsequent to the detecting, instantiating the remote VTEP for the remote network element on the local network element. Some embodiments may include detecting cessation of the unicast traffic from the local network element to the remote network element and subsequent to the detecting cessation, uninstantiating the remote VTEP for the remote network element from the local network element.

1. A method, comprising:
acquiring at a local network element information regarding a remote network element via a control protocol distribution method; refraining from instantiating a remote Virtual eXtensible Local Area Network Tunnel End Point (“VTEP”) for the remote network element on the local network element until unicast traffic from the local network element to the remote network element via an overlay network has begun; detecting unicast traffic from the local network element to the remote network element; subsequent to the detecting, instantiating the remote VTEP for the remote network element on the local network element installing on the local network element a host route tied to the remote network element; detecting whether the remote VTEP for the remote network element is instantiated on the local network element; instantiating the remote VTEP for the remote network element on the local network element if instantiation of the remote VTEP for the remote network element on the local network element is not detected; uninstantiating the remote VTEP for the remote network element from the local network element upon detection that all host routes to the remote network element are aged out on the local network element.
