1 C H A P T E R General Configuration of the Network Positioning System Configuration of the Network Positioning System (NPS) involves these tasks: 1 Configure your router so that it can communicate with the NPS. This includes assigning a hostname to the router. 2 Configure the Extensible Messaging and Presence Protocol (XMPP) server on one data center (DC)-facing provider edge router (PE). 3 Configure the Service Resolution Engine (SRE) on one DC-facing PE. 4 Configure the Capability Directory (CD) on the same DC-facing PE on which the SRE is configured. 5 Configure the Performance Manager (PFM) running on your router. This configuration changes depending on whether you are configuring a DC-facing or customer edge router (CE)-facing PE. 6 Configure the routing protocols on your router so that the Proximity Engine (PXE) can use these for proximity calculations. This module covers the basic configuration required so that your router can communicate with the NPS. Refer to the remaining modules in this book for information on other configuration tasks. • Configuring Basic Networking on a PE, page 1 Configuring Basic Networking on a PE To enable the XMPP server to access each CE-facing and DC-facing PE in the system, you must perform this configuration: OL-25794-01 Cisco Network Positioning System Configuration Guide for the Cisco ASR 1000 Router, Release 1.0 1
