1.  This message provides guidance and status information 
concerning the Defense Data Network (DDN) Mailbridge (MB) and the 
two functions which it fulfills:  (1) Internet Routing Service 
(IRS) using Exterior Gateway Protocol (EGP) and (2) DDN 
connectivity to the non MILNET Internet, commonly referred to as 
the NSFNET.  Request widest dissemination.  The following topics 
will be addressed:  
    --  EGP Update Options (see also Para 8, below, for detailed 
assignments).
     --  Randolph Mailbridge Network Address Change Effective
9 Sep 91.
    --  Non-compliance with Internet Control Message Protocol
(ICMP) Re-Direct Messages.
    --  Planned Relocations for Mailbridges.
    --  Planned NSFNET (Internet) Connection Changes.
    --  Replacement System for MB/EGP Servers.
    --  Detailed EGP Server Assignments. 

2.  EGP Update Options.  MB software Patch 11, fully deployed as 
of 30 Jul 91, provides the capability to restrict the EGP update 
size by eliminating announcement of networks and gateways served 
by the NSFNET and provides a default routing assignment (zero 
default route) to reach those non-advertized networks.  Due to the 
update size exceeding 8K bytes and after consultation with 
relevant gateway administrators and managers, the limited update 
was activated at BMILBBN, BMILISI, BMILDCEC, and BMILOAK.  Full 
MILNET/NSFNET network update announcements continue to be provided 
by BMILRAN, BMILAMES, and BMILMITRE at this time.  See Ref A for 
details.  See Para 8, below, for specific assignments. 

3. Randolph MB Network Address Change Effective 9 Sep 91.  As a 
result of the planned deactivation and removal of PSN 101 at 
Randolph AFB TX on 9 Sep 91, it is necessary to re-home the MB to 
node 51.  The new network address is 26.1.0.51.  All gateways 
acquiring EGP updates from the MB at Randolph should change their 
software accordingly.  Use of BMILAMES (26.20.0.16) or BMILMITRE 
(26.20.0.17) as a secondary source for full EGP updates, pending 
required changes, may be used as an interim alternative.  However, 
strict compliance with the assignments detailed in Para 8, below, 
is critical to overall operational effectiveness of the EGP 
service.  

4.  Non Compliance with ICMP Re-Direct Messages.  When the MB is 
used as a default route to other addresses, the MB searches its 
tables to see if a direct route is available.  If so, the MB sends 
a protocol message to the originating address of that packet 
advising of the direct address.  It is expected that properly 
implemented Internet protocol software will respond to that re- 
direct command for all subsequent packets destined for that 
address.  Many hosts/gateways are not responding to the re-direct 
commands, which results in extraneous packets (i.e., packet plus 
re-direct message plus retransmission for every packet) traversing 
the network and poorer response to the user.  This mis-use also 
adds additional processing requirements to an already stressed MB.  
In the future, chronic failure to respond to re-direct commands 
will be brought to the attention of the parent service/agency for 
corrective action.  Continued non-compliance may result in denial 
of re-direct service to the offending host/gateway with resultant 
lost traffic.

5.  Planned MB Relocations.  As a result of MILNET re-designs 
driven by changing requirements and funding cutbacks, the packet 
switching nodes currently connecting BMILAMES (26.20.0.16), 
BMILISI (26.6.0.103), and BMILMITRE (26.20.0.17) Mailbridges will 
be deactivated and the Mailbridges re-homed.   As soon as a firm 
re-home location and schedule is determined, an announcement of 
the new addresses will be provided.

6.  Planned Changes to the MILNET/NSFNET Connections.  In an 
effort to provide more efficient and economical service to those 
subscribers exchanging traffic between the MILNET and the NSFNET, 
or non-DoD Internet, it is planned to provide this 
interconnectivity via Internet protocol routers to be located at 
Ft Detrick (for the fix-east connection) and at Oakland (Navy) CA 
(for the fix-west connection).  MILNET entry points for this 
Internet traffic will be at one of eight IP router locations. This 
change will off load this store and forward function from 
BMILMITRE and BMILAMES Mailbridges and provide a more efficient
and economical exchange of MILNET/NSFNET traffic.  Further 
information and specific address assignments will be provided as 
this plan matures.  In the interim, Internet traffic should be
routed as specified in Ref C and DDN Management Bulletin 74.

7.  Replacement System for MB/EGP Servers.  As announced at Ref B, a
replacement system for Internet routing service is required because of
current Mailbridge hardware and software limitations in addition to
Exterior Gateway Protocol (EGP) limitations.  A detailed plan
describing this replacement system, along with a schedule of events,
is being forwarded under separate cover to principal offices of the
Deparment of Defense Services and Agencies for review, comment, and
concurrence.  The plan includes a migration from EGP to Border Gateway
Protocol (BGP) and replacement of the current Mailbridge hardware and
software within the next two years.  EGP will be supported, at least
to some degree, until all gateways can convert to BGP.  Status updates
and required modifications to subscriber gateways will be published as
needed.

8.  Detailed EGP Server Assignments.

    a.  Strict compliance with the assignments enumerated below is 
essential to providing adequate service to all users.  Failure to 
comply with these assignments could result in the denial of 
Internet routing service updates and/or exchange of traffic with 
the non DoD Internet.  Refs C and D previously requested 
assistance in this matter.

   b.  These EGP Server assignments supersede those provided by Ref C
and DDN Management Bulletin 74.

   c.  Air Force concentrators will continue to use either
BMILDCEC or BMILOAK as their EGP servers.  

   d.  Internet traffic assignments will remain as assigned by
Ref C and DDN Management Bulletin 74 (see Para 6, above).

   e.  Host/Gateway Administrators should initiate compliance 
with this message as soon as possible with complete compliance 
prior to 30 Sep 91.  

   f.  Questions or issues should be directed to the DDN
Monitoring Center Trouble Desks:

    	(1) CONUS:    1-800-451-7413 or (703) 486-1982 or 
    	  	      (DSN) 231-1787.
        (2) Europe:   (ETS) 430-5532 or (MIL) 2729-5532 or
          	      (DSN) 314-430-5532 or (CIV) 011-49-680-5532 
        (3) Pacific:  (808) 656-1472 or (DSN) 315-456-1472

   g.  The following network addresses apply: 

Mailbridge Name   Site Location      Network Address
 
AMES	          Moffett Field CA   26.20.0.16
BBN 	          Cambridge MA       26.20.0.72

ISI 	          Marina Del Rey CA  26.6.0.103
MITRE	          McLean VA	     26.20.0.17
OAK 	          Oakland CA	     26.1.0.148
RAN 	          Randolph AFB TX    26.3.0.101 (until 9 sep 91)
RAN 	          Randolph AFB TX    26.1.0.51  (after 9 sep 91)

   h.  Specific EGP assignments.  Each gateway should acquire as 
EGP peers (neighbors) only those two EGP servers assigned. Failure 
to comply may result in erroneous/conflicting updates or 
loss of capability to exchange traffic with both MILNET and non 
DoD Internet gateways.
