************************************************************************ DDN MGT Bulletin: 9409 DISA DDN Defense Communications System 10 Aug 1994 Published by: DDN Network Info Center (NIC@NIC.DDN.MIL) (800) 365-3642 DEFENSE DATA NETWORK MANAGEMENT BULLETIN The DDN MANAGEMENT BULLETIN is distributed online by the DDN Network Information Center under DISA contract as a means of communicating official policy, procedures and other information of concern to management personnel at DDN facilities.

The pathname for bulletins is ddn-news/ddn-mgt-bulletin-nn.txt (where "nn" is the bulletin number). ************************************************************************ SUBJECT: UPDATED DEFAULT GATEWAY AND T/20 ROUTE SERVER ASSIGNMENTS IMPORTANT - PLEASE READ - Switch over to new default gateways and T/20 Route Servers. This DDN Management Bulletin provides updated routing assignments for MILNET subscriber hosts and gateways. It supersedes DDN Management Bulletin 9303, dated 24 November 1993. The new routing assignments are effective immediately. Request MILNET subscriber hosts and gateways switch to the new assignments listed in this bulletin NO LATER THAN 12 SEPTEMBER 1994. The routing assignments for subscribers on 67 MILNET Packet-Switch Nodes (PSNs) have been changed in this revision, due in part to the reactivation of the Belvoir DDN Internet Protocol Router (IPR), 26.28.0.107, and load balancing among the DISN--MILNET interfaces. **************************************************************** 1. This bulletin provides two sets of routing assignments (Table A and Table B). Table A lists default gateway assignments for MILNET hosts or any gateway unable to obtain dynamic default routes directly from the T/20 route servers. Table B lists T/20 route server assignments for MILNET gateways. Refer to Section 2 for detailed implementation instructions. Section 4 lists technical contact telephone numbers for host and gateway administrators needing assistance. 2. At this time, the default gateways are the ten DISN Pilot Network IPRs with interfaces on MILNET. These DDN IPRs provide store-and-forward services for traffic between MILNET, DISN networks such as DCN and AFIN, and the civilian INTERNET. The T/20 route servers on MILNET provide dynamic routing information to MILNET subscriber gateways, including default gateway information. The following information explains the responsibilities of subscriber HOST administrators. Section 6 (Table A) lists default gateway assignments, by PSN, that MILNET subscriber hosts should use to configure their static default routes. Section 6 also applies to subscriber gateways which are unable to obtain dynamic default routes directly from the T/20 route servers. The following information explains the responsibilities of subscriber GATEWAY administrators. Section 7 (Table B) lists T/20 route server assignments, by PSN, that subscriber gateway administrators should use to configure the EGP or BGP neighbor addresses of the assigned T/20s. BGP remains the recommended protocol and subscribers should maintain the goal of converting to BGP (Refer to DDN Management Bulletin 9302). The T/20s will continue to provide EGP services to those subscribers that are not ready to switch to BGP. Users who want to test their capability to use BGP should contact the technical representative to perform a brief test prior to permanent change to BGP. To achieve optimal MILNET routing for traffic to/from the INTERNET, it is important that subscriber gateways prefer routes from the primary T/20 route server over routes from the secondary. This capability exists on most subscriber gateways. Specifically, it is possible to prefer routes from one EGP/BGP neighbor over another in both CISCO gateways and devices using the gateD software. If you require assistance configuring your gateway to accomplish this preference, please contact the technical representative listed in Section 4. 3. These routing assignments are designed to optimize routing within MILNET. COMPLIANCE with these assignments is CRITICAL to ensure adequate performance and service. Please keep in mind that geographical distances do not necessarily correspond to topological distances on the MILNET. The MILNET topology is changing as it downsizes. The assignments listed below will be reviewed periodically to ensure that routing continues to be optimal. Although efforts will be made to minimize change, significant topological changes may require future revisions to this bulletin. BBN will evaluate topology and traffic changes on a quarterly basis. 4. Questions about this bulletin should be addressed to: Maj John W. Lent Chief, DDN MILNET Operations DISA/UTDS DSN 222-2757 COMM (703) 692-2757 E-Mail lentj@cc.ims.disa.mil or milops@ddn-conus.ddn.mil Technical questions in the CONUS should be addressed to the CONUS MILNET Monitoring Center, 1-800-451-7413 or COMM (703) 692-2268. In Europe, technical questions should be addressed to the European MILNET Monitoring Center - ETS 430-5532. In the Pacific, technical questions should be addressed to the Pacific MILNET Monitoring Center - DSN 456-1472/1473/1474. 5. The DISN--MILNET routing strategy is implemented by dividing all of the MILNET PSNs into groups called CLUSTERS. The cluster simply defines the group of users that use a specific DDN IPR for off-MILNET traffic. All users connected to a PSN are considered to be within that PSN's cluster, and will use the DDN IPR assigned to that PSN. This cluster evaluation was based on MILNET routing information and traffic statistics from June 1994. The specific PSNs within a cluster were determined by performing a topological analysis of the MILNET and grouping PSNs with DDN IPRs so as to minimize average topological distance (in hops) to reach the DDN IPRs, minimize congestion, and balance traffic loads directed to the DDN IPRs. The following is the current list of clusters and their corresponding DDN IPRs: DDN IPR Cluster MILNET Addr Location ======== ======= =========== ============================= AMES AMES 26.19.0.16 Moffett Field, Mt.

Default gateways for MILNET subscriber HOSTS (Table A) MILNET HOST administrators must use this table to configure primary and secondary default routes. The secondary default route is suboptimal and should only be used as a backup in case the primary default route is unavailable. This table may also be used by gateways that are unable to obtain dynamic default routes from the T/20 route servers.
