It's December!!!!  (which year? :)

> The PRDB and this "NWG report" will be retired in December.  Details below.

> The following changes have been made to the NSFNET policy-based routing

> PRDB CHANGES:                                       (Updated October 25, 1994)
> In early December 1994, as part of the transition to the new Global
> Routing Registry (GRR), the Policy Routing Database (PRDB) will be retired.
> Many of the functions of the PRDB (including generation of router 
> configurations for NSFNET) will be produced based on data from the
> Global Routing Registry.  
> This change to the NSFNET Backbone service will involve the following changes:
>   - The method for submitting new nets to be routed over AS690 will
> 	change.  Instead of submitting a NACR to nsfnet-admin at,
> 	you will need to submit a "route template" to auto-dbm at .
>   - Additions and entries to the new registry will be made by the Home
> 	AS which creates the route for each net, rather than being 
> 	submitted by a AS690 peer AS.
>   - Most of the PRDB reports (listed above) will no longer be produced.
> 	Equivalent information for most of these reports is available
> 	from the global Routing Registry.
> These are major changes to the system.  These changes are being made in
> order to migrate NSFNET customers and the global user community to a
> Global Routing Registry system, which will be more capable of supporting
> user needs after the termination of the NSFNET Backbone services in
> April 1995.
