The CLI can be used to configure a P2MP policy, its CPs, and path instances on the root node. The CLI can also be used to create the replication segments on the root, transit, and leaf nodes. The P2MP policy can be assigned to NG-MVPN Inclusive P-Multicast Service Interfaces (IPMSIs) and Selective PMSIs (SPMSIs).
On each node, each replication segment represents a unique P2MP LSP with the following key: <tree ID, root ID, instance ID>. The instance ID and tree ID are unique to each root.
