  • Cisco LISP (Location Identifier Separation Protocol)

    LISP (Location Identifier Separation Protocol) is a routing and addressing architecture developed by Cisco Systems. LISP creates two addresses for each network node: one for its identity and another for its location in the network. 

  • IP address management (IPAM)

    Internet Protocol address management (IPAM) is a method of tracking and modifying the information associated with a network's Internet Protocol address (IP address) space. With IPAM, administrators can ensure that the inventory of assignable IP addre...
