The JUNOSe RADIUS route-download server provides periodic automatic distribution of IPv4 static access routes, which enables preconfiguration and preadvertising of access routes before they are assigned to clients. Using the route-download server helps eliminate routing protocol storms and other delays in client service activation that can be caused by protocol convergence or a large number of simultaneous customer activations.
The RADIUS route-download server periodically sends a RADIUS Access-Request message to the RADIUS server to request that routes be downloaded. The RADIUS server then responds with an Access-Accept message and downloads the configured routes. When the download operation is complete, the route-download server installs the access routes in the routing table.
JUNOSe software supports the creation of one RADIUS route-download server per chassis.
