         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.

     The following IP network addresses apply:

[* NOTE: On 31 July 1990, the address for the Randolph AFB mailbridge
was corrected to 26.3.0.101 in the online version of this bulletin.
The bulletin originally had the incorrect address of 26.30.0.101.]
