Change of Architecture for MILNET/NSFNET Connectivity
1. This message provides important guidance and status information concerning
communication between MILNET and the non-DoD Internet (e.g. NSFNET.) The
following topics will be addressed:
-The deployment of the new architecture between MILNET and
NSFNET via the Internet Protocol routers (IPRs) on the DISN-NT
Pilot Network.
-Status of the Cisco IPRs as default gateways providing
store-and-forward functionality for MILNET/NSFNET traffic.
-Status of Mailbridges as route servers for MILNET subscriber
gateways.
2. In an effort to provide more efficient and economical service to subscribers
exchanging traffic between MILNET and NSFNET, a new routing architecture has
been designed to interconnect MILNET and NSFNET via the Internet Protocol
routers (IPRs) on the DISN-NT Pilot Network. In this architecture, 8 Cisco
IPRs on the T1-backbone Pilot Network, together with the Cisco at FIX-West,
will provide the store-and-forward functionality for traffic between MILNET and
the rest of the Internet. The Mailbridges will continue to function as route
servers for MILNET subscriber gateways, provide routing information via the
External Gateway Protocol (EGP).
Incoming traffic to the MILNET will be diverted to the IPR closest to the
destination network. Outgoing traffic to NSFNET will be routed in two ways:
- -MILNET hosts will statically default to the IPR closest to
them, and
- -MILNET gateways will obtain a dynamic default for NSFNET
traffic via EGP updates from the Mailbridges. The default IPR will be
advertized as the next hop to both the default NSFNET backbone network,
129.140.0.0 and to network 0.0.0.0 .
Two assignment lists are given in this bulletin to provide MILNET
users with the proper IPRs to use for defaults. One list (section 5)
contains a primary and a secondary IPR for each PSN. This is to be
used by MILNET hosts that need static default information. The other
list (section 6) contains, for each PSN, the primary and secondary
Mailbridges to use as EGP peers. This is for MILNET subscriber
gateways which will obtain the default IPR dynamically from the
Mailbridges via EGP updates.
This routing architecture is planned to take effect on June 22, 1992.
3. In addition to the Ciscos at FIX-West and Ft. Detrick, the Cisco
IPRs on the Pilot Network will be default gateways providing
store-and-forward functionality for MILNET users. MILNET hosts that
configure a static default gateway should follow the assignment list
given in section 6. MILNET gateways will obtain the proper default
IPR via EGP updates with the mailbridges.
The IP address of the Cisco IPRs on the Pilot Network are:
Detrick 26.29.0.54
Reston 26.29.0.104
Belvoir 26.29.0.142
Lewis 26.29.0.159
Huachuca 26.25.0.122
Gunter 26.24.0.13
Randolph 26.17.0.51
Oakland 26.29.0.207
Ames 26.19.0.26
Please note that the Cisco at FIX-West (Ames) is not yet connected
to the Pilot Network via a T1 link.
4. DISA plans to deploy Mailbridge patch 18 on June 22, 1992 to accompany
the deployment of the FIX-East architecture. In this patch, all
Mailbridges will provide routing information about MILNET networks,
one NSFNET backbone network, 129.140.0.0, and network 0.0.0.0 in their
EGP updates.
The Mailbridges will be configured with a list of IPRs to use as
default gateways for traffic destined for NSFNET. The default IPR
will be advertised as the next hop to BOTH network 129.140.0.0, the
NSFNET backbone network, and to network 0.0.0.0. The list
of default IPRs configured for each Mailbridge is as follows:
MB 1 2 3 4 5 6 7 8 9

(26.1.0.148)
BMILRICH BELV GUNT DETR AMES DCEC HUAC RAND LEWI OAK
(26.3.0.246)
The Mailbridges will always advertise the first configured default
gateway if it is reachable. If not, the second configured default
gateway will be choosen, and so on.
In order to provide MILNET subscriber gateways with more reliable
routing information, the status of the Mailbridges as MILNET core
route servers is constantly under review. It is likely that the core
system, currently consisted of Mailbridges only, will be upgraded in
the near future. Status updates and required modifications to
subscriber gateways will be published as the plan matures."
5. Static Default Assignment
This assignment provides MILNET users with a primary and a secondary IPR
to use as static defaults for outbound traffic from MILNET to NSFNET.
All hosts and gateways which cannot take advantages of dynamic routing
should used the appropriate IPRs as their default gateways so that
traffic within MILNET will be minimized.

6. EGP Server Assignment
This assignment provides the MILNET gateways with the Mailbridges to
use as primary and secondary EGP peers. This assignment ensures that
outbound traffic from MILNET to NSFNET will be routed to the IPR
closest to the gateway so that traffic within MILNET will be
minimized. In order for outbound traffic to be routed optimally, it
is ESSENTIAL for MILNET gateways to comply with the assignments in this
list.
As before, the list is based on MILNET PSNs.
