| "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)."; |
