Configuring Topology Discovery
You use the discovery-mode command to enable the dynamic discovery of access topology. When ANCP discovery is enabled, an authentication server (like RADIUS) retrieves upstream and downstream access loop information from the configured access node.
For information about configuring RADIUS, see JUNOSe Broadband Access Configuration Guide, Chapter 3, Configuring RADIUS Attributes.
