10 NLSP Configuration Commands Router (config) # Ipx internal-network network-number  Sets network number for the IPX router Router (config) # Ipx router nlsp tag Enables NLSP on the router

11 NLSP Configuration Commands (cont.) Router (config-ipx-router) # Area-address address mask  Defines the NLSP area number Router (config-if) # Ipx nlsp enable Starts NLSP routing on an interface
