Abstract: Techniques are disclosed for configuring a LISP mobility network. A management tool receives a configuration for a network fabric. The configuration specifies values for one or more attributes associated with a Locator ID Separation Protocol (LISP)-enabled network. The management tool generates one or more commands based on the specified values for the one or more attributes associated with the LISP-enabled network. The generated commands are distributed to a plurality of network devices in the network fabric. Each network device executes the one or more commands to configure the network fabric.

Abstract: Multi-destination frames in a network fabric may be carried in IP multicast packets. As such, the network fabric may us IP multicast technique such as a PIM protocol for handling the multi-destination frames. To provide redundancy, the system administrator can use phantom rendezvous points (RPs) that include multiple physical RPs where one of the RPs serves as a primary RP and the other RPs serve as secondary RPs (e.g., backup RPs). Instead of the system administrator manually configuring the phantom RPs, the RPs are automatically configured. To do so, the system administrator may use a GUI to provide multicast groups allocated for the multi-destination traffic, the number of desired phantom RPs (or physical RPs), and the desired RP redundancy. Based on these parameters, a data center manager generates one or more templates that automatically configure the network devices in the fabric as they are booted.
