  • Patent number: 10999239
    Abstract: A Location/Identifier Separation Protocol (LISP) mapping server, including: a network interface for communicating with a LISP-enabled network; a mapping database; a subscription database; and an overlapping subscription publication engine (OSPE) to: receive a first mapping of a first subnetwork to a first routing locator (RLOC); add the first mapping to the mapping database; receive from a first ingress tunnel router (ITR) a subscription request for an endpoint identifier (EID) within the first subnetwork; add to a first subscription entry for the first subnetwork in the subscription database a subscription for the first ITR; receive a second mapping of a second subnetwork to a second RLOC, wherein the second subnetwork overlaps the first subnetwork; add the second mapping to the mapping database; and copy at least part of the first subscription entry to a second subscription entry for the second subnetwork.
    Type: Grant

  • Patent number: 10771390
    Abstract: One embodiment of a method includes receiving at a first network node traffic from a second network node; and sending by the first network node to a third network node information identifying the second network node via a Local Area Network (“LAN”) connection between the first and third network nodes. Subsequent to receipt of the information identifying the second network node, the third network node updates a locator table maintained by the third network node to include an entry including the information identifying the second network node received by the third network node from the first network node. Upon receipt by the third network node of a notification that the first network node has failed, the third network node sends an update only to network nodes that have an entry in the locator table indicating that the first network node has failed.
