- Status of this Memo
-
- This document is an Internet Draft. Internet Drafts are working
- documents of the Internet Engineering Task Force (IETF), its Areas,
- and its Working Groups. Note that other groups may also distribute
- working documents as Internet Drafts.
- Internet Drafts are draft documents valid for a maximum of six months.
- Internet Drafts may be updated, replaced, or obsoleted by other
- documents at any time. It is not appropriate to use Internet Drafts
- as reference material or to cite them other than as a ``working
- draft'' or ``work in progress.''
- Please check the I-D abstract listing contained in each Internet Draft
- directory to learn the current status of this or any other Internet
- Draft.
-
- Abstract
- The document ``MHS Use of Directory to support MHS Routing'' describes
- a comprehensive approach to MHS use of directory to support routing
- [1]. This document defines a strict subset of this document, which is
- intended to solve the most pressing problems. It also defines a
- practical first step for implementation, such that this subset can be
- deployed prior to fuller implementation.
- This document does not repeat information in the other document.
- Duplication would only lead to the possibility of inconsistency.
-
-
- WARNING: This document must be read in the contex of the document it
- profiles. It is meaningless as a standalone document.
-
- This draft document will be submitted to the RFC editor as a protocol
- standard. Distribution of this memo is unlimited. Please send
- comments to the author or to the discussion group
- <mhs-ds@mercury.udev.cdc.com>.

-
- 1 Service Goals
-
- The following goals are identified:
-
-
- o No routing table configuration for simple MTAs in a PRMD (WEPs and
- gateways may do manual things).
-
- o Single entry configuration for most sites.
-
- o Do not replace function that is working reasonably well using
- existing approaches.
-
- o Ignore issues which are not yet operational concerns. These can
- be handled by the full specification in due course.
-
-
- 2 Approach
-
- The approach to routing is to use the single routing tree associated
- with the open community. MTAs will reference this tree. Simple MTAs
- need only do this, plus ad hoc configuration to route to a suitable
- MTA with a fuller manual configuration (e.g., a WEP). This document
- goes through section by section, referencing the full document, noting
- what support is needed.

-
- 3 Profile
-
- 3.1 General Table Handling
-
-
- Support for subtrees, but not flat tables is needed.
-
- 3.2 O/R Address Hierarchy
-
-
- Support for all attributes is needed, except:
-
- mHSX121
-
- mHSDomainDefinedAttribute
-

-
-
- 3.3 Local Addresses
-
- This is supported.
-
-
- 3.4 MTA Naming
-
- All MTAs are named within the O/R Address tree. The attributes which
- must be supported are:
-
- responderAuthenticationRequirements
-
- transportCommunity
-
- remotePresentationAddress
-
-
- 3.5 Routing Trees
-
- Only the single open community routing tree must be used. A variant
- on this profile might relax this restriction, perhaps to support a
- small number of routing trees. This relaxation should be noted in any
- statment referencing this specification.
-
-
- 3.6 Routing Information
-
- The following attributes are used:
-
-
- o authoritativeAddress
-
- o mTAInfo
-
- Routing action is always the default.
-
-
- 3.7 Indirect Connectivity
-
- This is not used.

-
-
- 3.8 Protocol Mismatches
-
- The transport community approach is used.
-
-
- 3.9 Supported Protocols
-
- This approach is used, but only P1(88) and P1(84) are considered.
-
- 3.10 Capability Restrictions
-
-
- These are not handled.
-
- 3.11 Pulling Messages
-
-
- This is not done.
-
- 3.12 Authentication
-
-
- For 1988 usage, the distinguished name is used to identify the remote
- MTA. Authentication will be by network address. Password will always
- be a zero length OCTET STRING.
- For 1984 usage, no authentication is done.
- The attribute must be supported, but only the
- responderAuthenticationRequirements attribute is used. For MTAs
- following this specification, the following values must be set if
- bilateral-agreement-needed is false.
-
-
- mta-name-present true
-
- aet-present true
-
- aet-valid true
-
- network-address true
-
- simple-authentication false
-
- strong-authentication false
-

-
-
- If bilateral-agreement-needed is true, there are no restrictions on
- value. Where a WEP uses this scheme, information on the bilateral
- agreement will be determined locally (by private means).
- The remotePresentationAddress attribute will always be present.
-
-
- 3.13 Policy
-
- Policy will not be used.
-
- 3.14 Protocol Extensions
-
-
- These will not be used.
-
- 3.15 Format Conversion
-
-
- All issues relating to format conversion will be ignored.
-
- 3.16 RFC 822 Support
-
-
- There is no support for RFC 822 or RFC 822/X.400 mappings by use of
- directory.
-
- 3.17 Distribution Lists
-
- This will not be supported.
-
-
- 3.18 Redirects
-
- Not supported.
-
-
- 3.19 Bad Addresses
-
- The mechanisms will not be supported.
