The ICND exam had some routing table entries with "P" as the routing code. I couldn't find anything in the book or on-line that explains the concept of periodic downloaded static route, and it threw me for a loop. Anyone have a simple explanation?
Static routes can be dynamically downloaded from an AAA server by the
network access servers, or be manually configured on the network access
servers. Dynamic static routes are installed on the network access server by
an AAA server. The routes are downloaded at system startup and updated
periodically, so that route changes are reflected within a configurable
interval of time.
