+ description
+ "This module describes configuration and operational state data
+ for routes that are locally generated, i.e., not created by
+ dynamic routing protocols. These include static routes, locally
+ created aggregate routes for reducing the number of constituent
+ routes that must be advertised, summary routes for IGPs, etc.
+
+ This model expresses locally generated routes as generically as
+ possible, avoiding configuration of protocol-specific attributes
+ at the time of route creation. This is primarily to avoid
+ assumptions about how underlying router implementations handle
+ route attributes in various routing table data structures they
+ maintain. Hence, the definition of locally generated routes
+ essentially creates 'bare' routes that do not have any protocol-
+ specific attributes.
+
+ When protocol-specific attributes must be attached to a route
+ (e.g., communities on a locally defined route meant to be
+ advertised via BGP), the attributes should be attached via a
+ protocol-specific policy after importing the route into the
+ protocol for distribution (again via routing policy).";
