    Abstract: A method for assisting communication of a source host upon movement from a first Data center (DC) to a second DC is disclosed. The method includes identifying that the source host has moved from the first DC to the second DC, ensuring that packets identifying a source as the source host in the second DC are copied to a control plane network element, and, for a first destination host identified in a first packet copied to the control plane network element and identified as a host that is not in the second DC, updating an Address Resolution Protocol (ARP)/Neighbor Discovery Protocol (NDP) cache of the source host by sending, to the source host, a first ARP message/unsolicited neighbor advertisement specifying a Media Access Control (MAC) address of an edge router associated with the source host in the second DC as a destination MAC address for the first destination host.

    Abstract: In one embodiment, a method includes discovering at a network device, a change in a resource at a local network site, notifying a load balancer at the local network site of the change in the resource, dynamically updating a weight associated with the resource, and transmitting the weight from the network device to a mapping system configured for mapping endpoint identifiers to routing locators. An apparatus and logic are also disclosed herein.

    Abstract: According to one example embodiment, an EID-NOTIFY packet is defined for use with the Location/Identifier Separation Protocol (LISP). A first-hop network element may send EID-NOTIFY responsive to decoding a data packet from a previously undetected host on its subnetwork. A site network element may receive EID-NOTIFY, and send a MAP-REGISTER message to a mapping system. EID-NOTIFY may have substantially the same format as MAP-NOTIFY. This may enable the site network element to be removed more than one hop from the subnetwork.

    Abstract translation: 根据一个示例实施例，EID-NOTIFY分组被定义为与位置/标识符分离协议（LISP）一起使用。 第一跳网络元件可以响应于从其子网上以前未检测到的主机解码数据分组而发送EID-NOTIFY。 站点网元可以接收EID-NOTIFY，并向映射系统发送MAP-REGISTER消息。 EID-NOTIFY可能具有与MAP-NOTIFY基本相同的格式。 这可以使站点网络元素从子网中移除多于一个跳。
