MANAGEMENT BULLETIN
The DDN MANAGEMENT BULLETIN is distributed online by the DDN Network
Information Center under DCA contract as a means of communicating
official policy, procedures and other information of concern to
management personnel at DDN facilities. Back issues may be read
through the TACNEWS server ("@n" command at the TAC) or may be
obtained by FTP (or Kermit) from the NIC.DDN.MIL host [192.67.67.20]
using login="anonymous" and password="guest". The pathname
for bulletins is DDN-NEWS:DDN-MGT-BULLETIN-nn.TXT (where "nn" is the
bulletin number).

MILNET Gateway and Internet Traffic Homing Announcement
PURPOSE:
This announcement defines software configuration changes that must be made
to each MILNET gateway in order to acquire Exterior Gateway Protocol (EGP)
Service. It also defines software configuration changes that must be
applied to MILNET hosts sending traffic to subscribers on the Internet.
This announcement replaces DDN Management Bulletin 49, ARPANET and MILNET
Host Rehoming Announcement dated 23 DEC 88 and DDN Management Bulletin 53,
ARPANET and MILNET Gateway Rehoming Announcement dated 12 JAN 89.
-- For EGP Service, these changes are required due to the extensive
growth in the number of gateways served on the MILNET and to alleviate
performance problems in the EGP Servers.
-- For Internet Traffic, these changes are required as a result of the
termination of the ARPANET and the replacement connections between MILNET
and the NSFNET.
(NOTE: Air Force Concentrators/Gateways are exempt
from this change. Through agreements reached
between DCA and the Air Force, those Concentrators
will be assigned to one of two EGP Servers (DCEC
or LBL). The Air Force has the capability to
implement global changes to their Concentrators
and has agreed to test and possibly implement
several changes in the EGP process which will be
beneficial to all.)
A secondary purpose of this Bulletin is to acquire information concerning
the capabilities and limitations of gateways on the MILNET in order to
design and implement future changes to improve EGP Service. Gateway
administrators are requested to identify their capability to: (1) modify
EGP service parameters that will permit negotiation of updates at variable
intervals from three minutes to one hour in order to reduce the frequency
of updates, and (2) request EGP service from a single server (versus
automatically sending to two servers) and modify that assignment quickly if
needed. Also, as the number of networks in the Internet grows, the size of
the EGP update continues to grow, and may exceed 4K bytes over the next
year. Please note any limitations in your gateways to accommodate such
large updates. This information should be sent to:
Defense Communications Engineering Center
Code DRFDS (Mr Dennis Morris)
1860 Wiehle Avenue
Reston Virginia 22090-5500
(Electronic Mail Address is MorrisD@imo-uvax.dca.mil)
TECHNICAL NOTES:
The upper range value of the EGP neighbor acquisition poll interval was
recently increased from 600 seconds to 3600 seconds to permit less frequent
polling for those gateways that can effectively function with an extended
polling time. Reducing the number of polls will, of course, reduce the
loading on the EGP Servers. Gateway administrators are encouraged to
implement the most INFREQUENT poll time that can be supported. Contact the
Mailbridge Hot Line at 1-800-492-4992 or (617) 873-3571 for clarification
and/or assistance in defining EGP Server interface characteristics.
EGP Server assignments are based primarily upon the network minimum hop
path between the Packet Switching Node (PSN) to which the Gateway is
connected and the PSN to which the EGP Server is connected. This logical
path is dependent upon network topology and does not necessarily have any
geographical basis.
Internet Traffic assignments are based upon historical traffic volumes.
The use of MITRE as the primary address for most hosts is the result of the
predominant Internet Traffic MILNET host being assigned to AMES for its
primary address.
SCHEDULE:
It is intended that these changes be made on a single week-end. Changes
may be implemented beginning at 2100 hours local time on Friday, 10 AUG 90
and should be completed no later than 0600 hours local time on Monday,
13 AUG 90.
Questions or issues should be directed to:
BBNCC Mailbridge Hot Line at 1-800-492-4992 or (617) 873-3571.
It is critical that these changes be accomplished; otherwise, EGP
service and exchange of traffic with the Internet may be inadequate.
These changes are designed to result in equal sharing of the user
demand over the Mailbridges. The changes will be verified and
non-compliance will be reported to the parent Service/Agency
organization for corrective action.
NETWORK ADDRESSES:
This section provides a list of assignments for the PSN to which the
gateways or hosts are homed and their assigned EGP Servers and Internet
Traffic Servers.
-- For Gateway Administrators.
The entries under the column heading "EGP Servers" provides a list
of assignments between the PSN to which the gateways are homed and their
defined EGP Servers. Each Gateway should acquire as EGP peers (neighbors)
only those two Servers assigned. As an example, all gateways connected to
MILNET PSN Number 64 (ROBIN) should assign MITRE (26.20.0.17) and, if
necessary, BBN (26.20.0.72) as their EGP servers.
-- For Host Administrators.
The entries under the column heading "Internet Traffic" provide a
list of assignments between the PSN to which hosts are homed and their
default gateway or Internet Traffic Server. As an example, all hosts
connected to MILNET PSN Number 64 (ROBIN) should send non-MILNET traffic to
MITRE (26.20.0.17), or to AMES (26.20.0.16) when MITRE is unavailable.
