Specifying a layer-3 MLPA in the IRR
by Jake Khuon 16 Jan '98

16 Jan '98

Although I've already sent this to the routing WG mailing list, Gerald Winters suggested that the DB WG might be interested in at least the authorisation schema. I have written two draft proposals (one for RIPE-181 and the other for RPSL) on how to specify layer-3 MLPAs in the IRR. I'd like to welcome any comments. I'm including a copy of each draft below and they can also be found at: http://espresso.merit.net/~khuon/khuon-003.txt http://espresso.merit.net/~khuon/khuon-004.txt #include <khuon-003.txt> Specifying and Supporting a Layer-3 MLPA Using as-macros Jake Khuon Merit Network, Inc. Document ID: khuon-003 November, 1997 ABSTRACT This document describes a procedure and mechanism for implementing layer-3 MLPA support in the Internet Routing Registry using RIPE-181 as-macros. khuon-003.txt November, 1997 - 2 - Table of Contents 1 Introduction ................................................ 2 2 Organisation of this Document ............................... 2 3 Proposed Construction of an MLPA as-macro ................... 2 4 Architecture for an Authorisation and Control Mechanism for Maintaining an MLPA as-macro ................................ 3 5 References .................................................. 5 6 Author Address .............................................. 6 1. Introduction Several exchange points are making use of Multi-Lateral Peering Agreements to simplify both layer-2 and layer-3 peering. However, there is currently no mechanism to support those agreements to simplify router configuration. The most logical vehicle for specifying such an arrangement is the as-macro which is defined in [1]. Please refer to that document for more details. In the most general case, an MLPA is an agreement signed by members who wish to participate in a mutual full-mesh peering environment. This full-mesh may inhabit both layer-2 and/or layer-3. The concern with using as-macros for specifying an MLPA is that of scope of control. This macro must be modifiable by all organisations listed in the object, but one organisation should not be able to modify an attribute which references another organisation. I would like to acknowledge the contributions made by several people during the development of this document. Abha Ahuja helped in the initial design of the prescreening authorisation mechanism and Gerald Winters provided valuable input about the security considerations of the RIPE-181 language. 2. Organisation of this Paper This paper acts as both a guideline for registering MLPA-based as-macros and provides a schema for implementing a mechanism by which to handle proper control of those objects. Section 3 provides a suggested method for construction of the as-macro. Section 4 provides an architecture to be used to control maintenance of that object. 3. Proposed Construction of an MLPA as-macro The MLPA as-macro is constructed in much the same way as any other as-macro with the exception that the specified mnt-by references a controlling body which does not belong to any one organisation khuon-003.txt November, 1997 - 3 - listed. To provide for simpler implementation of the control mechanism, it is suggested that only one aut-num be referenced in each as-list attribute. It is also suggested that no as-macros be referenced by an as-list and that naming convention be strictly adhered to which would reference an aut-num to its mntner. Example: as-macro: AS-AADSMLPA descr: MLPA participants at the AADS NAP as-list: AS4550 as-list: AS683 as-list: AS2551 as-list: AS5646 as-list: AS2685 guardian: auto-mlpa(a)ameritech.net admin-c: Andrew Schmidt tech-c: Mark Cnota notify: mlpa-participants(a)ameritech.net mnt-by: MAINT-AADSMLPA mnt-by: MAINT-RSPEER changed: auto-mlpa(a)ameritech.net 971123 source: RADB The mntner MAINT-AADSMLPA referenced above may look something like: Example: mntner: MAINT-AADSMLPA descr: People authorised to make changes for the AADS MLPA as-macro admin-c: Andrew Schmidt upd-to: noc(a)ameritech.net mnt-nfy: noc(a)ameritech.net auth: PGP-FROM noc(a)ameritech.net auth: PGP-FROM auto-mlpa(a)ameritech.net mnt-by: MAINT-AADSMLPA changed: noc(a)ameritech.net 971123 source: RADB In the above examples you will notice a reference to auto-mlpa(a)ameritech.net. Behind this email address will reside the actual gateway by which each of the organisations listed in the as-lists can submit changes. The details of this mechanism will be described below in Section 4. 4. Architecture for an Authorisation and Control Mechanism for Maintaining an MLPA as-macro The difficulty with using as-macros to specify an MLPA is the inability to implement a distributed and scoped authorisation mechanism for a single object. This document proposes a workaround by which an automated mailing list feeds a preprocessor that in turn will pre-authorise any object submissions before it itself submits the object through the traditional auto-dbm processor. Using the example above, auto-mlpa(a)ameritech.net is authorised to submit changes to AS-AADSMLPA. The auto-mlpa(a)ameritech.net mail khuon-003.txt November, 1997 - 4 - alias should point to a process which examines the submitted object and performs the following actions in the following order: 1. Determine the difference between the submitted object and current object. It should categorise these differences as one of the following operations: A. Addition of a new as-list B. Deletion of a current as-list If the submitted object contains an addition, it is advised that an as-macro containing a list of all the organisation's ASes present at that exchange point be further interrogated to determine if the addition may proceed. This is to prevent someone from just simply adding bogus ASes to the as-macro. 2. Interogate the aut-num reference listed in the as-list and determine via that aut-num's mnt-by if the submitter of the object is authorised. 3. Extract the object from the original email submission and resubmit it to the auto-dbm process of the database using the authentication method listed in the mntner of the as-macro (PGP signed in the above example). The following outlines an example of the process architecture: Suppose AS61234 (bogus.com) wishes to add itself to the AS-AADSMLPA macro. The submitter at AS1234 would submit a copy of the changed as-macro to the auto-mlpa preprocessor/gateway... v===============================================v as-macro: AS-AADSMLPA descr: MLPA participants at the AADS NAP as-list: AS4550 as-list: AS683 as-list: AS2551 as-list: AS5646 as-list: AS2685 as-list: AS61234 guardian: auto-mlpa(a)ameritech.net admin-c: Andrew Schmidt tech-c: Mark Cnota notify: mlpa-participants(a)ameritech.net mnt-by: MAINT-AADSMLPA mnt-by: MAINT-RSPEER changed: auto-mlpa(a)ameritech.net 971123 source: RADB ^===============================================^ | | | [pgp -sta -u noc] [(sign via PGP) ] | +------------------- <noc(a)bogus.com> khuon-003.txt November, 1997 - 5 - | | | v [ -- auto-mlpa -- ] [1.

Any Perl5 version before 5.004_04 contains memory leaks of some sort, and even 5.004_04 probably still contains some. Perl 4.036 seemed not too bad, but that's an ancient version now, so I wouldn't bet on it. Hope this helps, Steven

-- >>>> This is to confirm that your message has been received by **** Command 'this' not recognized. >>>> Island Internet's support department. **** Command 'island' not recognized. >>>> >>>> Thank you, **** Command 'thank' not recognized. >>>> Island Internet **** Command 'island' not recognized. >>>> >>>> **** No valid commands found. **** Commands must be in message BODY, not in HEADER. **** Help for Majordomo(a)tradinghouse.com: This help message is being sent to you from the Majordomo mailing list management system at Majordomo(a)tradinghouse.com. This is version 1.94.3 of Majordomo. If you're familiar with mail servers, an advanced user's summary of Majordomo's commands appears at the end of this message. Majordomo is an automated system which allows users to subscribe and unsubscribe to mailing lists, and to retrieve files from list archives. You can interact with the Majordomo software by sending it commands in the body of mail messages addressed to "Majordomo(a)tradinghouse.com". Please do not put your commands on the subject line; Majordomo does not process commands in the subject line. You may put multiple Majordomo commands in the same mail message. Put each command on a line by itself. If you use a "signature block" at the end of your mail, Majordomo may mistakenly believe each line of your message is a command; you will then receive spurious error messages. To keep this from happening, either put a line starting with a hyphen ("-") before your signature, or put a line with just the word end on it in the same place. This will stop the Majordomo software from processing your signature as bad commands. Here are some of the things you can do using Majordomo: I. FINDING OUT WHICH LISTS ARE ON THIS SYSTEM To get a list of publicly-available mailing lists on this system, put the following line in the body of your mail message to Majordomo(a)tradinghouse.com: lists Each line will contain the name of a mailing list and a brief description of the list. To get more information about a particular list, use the "info" command, supplying the name of the list. For example, if the name of the list about which you wish information is "demo-list", you would put the line info demo-list in the body of the mail message. II. SUBSCRIBING TO A LIST Once you've determined that you wish to subscribe to one or more lists on this system, you can send commands to Majordomo to have it add you to the list, so you can begin receiving mailings. To receive list mail at the address from which you're sending your mail, simply say "subscribe" followed by the list's name: subscribe demo-list If for some reason you wish to have the mailings go to a different address (a friend's address, a specific other system on which you have an account, or an address which is more correct than the one that automatically appears in the "From:" header on the mail you send), you would add that address to the command. For instance, if you're sending a request from your work account, but wish to receive "demo-list" mail at your personal account (for which we will use "jqpublic(a)my-isp.com" as an example), you'd put the line subscribe demo-list jqpublic(a)my-isp.com in the mail message body. Based on configuration decisions made by the list owners, you may be added to the mailing list automatically. You may also receive notification that an authorization key is required for subscription. Another message will be sent to the address to be subscribed (which may or may not be the same as yours) containing the key, and directing the user to send a command found in that message back to Majordomo(a)tradinghouse.com. (This can be a bit of extra hassle, but it helps keep you from being swamped in extra email by someone who forged requests from your address.) You may also get a message that your subscription is being forwarded to the list owner for approval; some lists have waiting lists, or policies about who may subscribe. If your request is forwarded for approval, the list owner should contact you soon after your request. Upon subscribing, you should receive an introductory message, containing list policies and features. Save this message for future reference; it will also contain exact directions for unsubscribing. If you lose the intro mail and would like another copy of the policies, send this message to Majordomo(a)tradinghouse.com: intro demo-list (substituting, of course, the real name of your list for "demo-list"). III. UNSUBSCRIBING FROM MAILING LISTS Your original intro message contains the exact command which should be used to remove your address from the list. However, in most cases, you may simply send the command "unsubscribe" followed by the list name: unsubscribe demo-list (This command may fail if your provider has changed the way your address is shown in your mail.) To remove an address other than the one from which you're sending the request, give that address in the command: unsubscribe demo-list jqpublic(a)my-isp.com In either of these cases, you can tell Majordomo(a)tradinghouse.com to remove the address in question from all lists on this server by using "*" in place of the list name: unsubscribe * unsubscribe * jqpublic(a)my-isp.com IV. FINDING THE LISTS TO WHICH AN ADDRESS IS SUBSCRIBED To find the lists to which your address is subscribed, send this command in the body of a mail message to Majordomo(a)tradinghouse.com: which You can look for other addresses, or parts of an address, by specifying the text for which Majordomo should search. For instance, to find which users at my-isp.com are subscribed to which lists, you might send the command which my-isp.com Note that many list owners completely or fully disable the "which" command, considering it a privacy violation. V. FINDING OUT WHO'S SUBSCRIBED TO A LIST To get a list of the addresses on a particular list, you may use the "who" command, followed by the name of the list: who demo-list Note that many list owners allow only a list's subscribers to use the "who" command, or disable it completely, believing it to be a privacy violation. VI. RETRIEVING FILES FROM A LIST'S ARCHIVES Many list owners keep archives of files associated with a list. These may include: - back issues of the list - help files, user profiles, and other documents associated with the list - daily, monthly, or yearly archives for the list To find out if a list has any files associated with it, use the "index" command: index demo-list If you see files in which you're interested, you may retrieve them by using the "get" command and specifying the list name and archive filename. For instance, to retrieve the files called "profile.form" (presumably a form to fill out with your profile) and "demo-list.9611" (presumably the messages posted to the list in November 1996), you would put the lines get demo-list profile.form get demo-list demo-list.9611 in your mail to Majordomo(a)tradinghouse.com. VII. GETTING MORE HELP To contact a human site manager, send mail to Majordomo-Owner(a)tradinghouse.com. To contact the owner of a specific list, send mail to that list's approval address, which is formed by adding "-approval" to the user-name portion of the list's address. For instance, to contact the list owner for demo-list(a)tradinghouse.com, you would send mail to demo-list-approval(a)tradinghouse.com. To get another copy of this help message, send mail to Majordomo(a)tradinghouse.com with a line saying help in the message body. VIII.

This is version 1.94.3 of Majordomo. If you're familiar with mail servers, an advanced user's summary of Majordomo's commands appears at the end of this message. Majordomo is an automated system which allows users to subscribe and unsubscribe to mailing lists, and to retrieve files from list archives. You can interact with the Majordomo software by sending it commands in the body of mail messages addressed to "Majordomo(a)tradinghouse.com". Please do not put your commands on the subject line; Majordomo does not process commands in the subject line. You may put multiple Majordomo commands in the same mail message. Put each command on a line by itself. If you use a "signature block" at the end of your mail, Majordomo may mistakenly believe each line of your message is a command; you will then receive spurious error messages. To keep this from happening, either put a line starting with a hyphen ("-") before your signature, or put a line with just the word end on it in the same place. This will stop the Majordomo software from processing your signature as bad commands. Here are some of the things you can do using Majordomo: I. FINDING OUT WHICH LISTS ARE ON THIS SYSTEM To get a list of publicly-available mailing lists on this system, put the following line in the body of your mail message to Majordomo(a)tradinghouse.com: lists Each line will contain the name of a mailing list and a brief description of the list. To get more information about a particular list, use the "info" command, supplying the name of the list. For example, if the name of the list about which you wish information is "demo-list", you would put the line info demo-list in the body of the mail message. II. SUBSCRIBING TO A LIST Once you've determined that you wish to subscribe to one or more lists on this system, you can send commands to Majordomo to have it add you to the list, so you can begin receiving mailings. To receive list mail at the address from which you're sending your mail, simply say "subscribe" followed by the list's name: subscribe demo-list If for some reason you wish to have the mailings go to a different address (a friend's address, a specific other system on which you have an account, or an address which is more correct than the one that automatically appears in the "From:" header on the mail you send), you would add that address to the command. For instance, if you're sending a request from your work account, but wish to receive "demo-list" mail at your personal account (for which we will use "jqpublic(a)my-isp.com" as an example), you'd put the line subscribe demo-list jqpublic(a)my-isp.com in the mail message body. Based on configuration decisions made by the list owners, you may be added to the mailing list automatically. You may also receive notification that an authorization key is required for subscription. Another message will be sent to the address to be subscribed (which may or may not be the same as yours) containing the key, and directing the user to send a command found in that message back to Majordomo(a)tradinghouse.com. (This can be a bit of extra hassle, but it helps keep you from being swamped in extra email by someone who forged requests from your address.) You may also get a message that your subscription is being forwarded to the list owner for approval; some lists have waiting lists, or policies about who may subscribe. If your request is forwarded for approval, the list owner should contact you soon after your request. Upon subscribing, you should receive an introductory message, containing list policies and features. Save this message for future reference; it will also contain exact directions for unsubscribing. If you lose the intro mail and would like another copy of the policies, send this message to Majordomo(a)tradinghouse.com: intro demo-list (substituting, of course, the real name of your list for "demo-list"). III. UNSUBSCRIBING FROM MAILING LISTS Your original intro message contains the exact command which should be used to remove your address from the list. However, in most cases, you may simply send the command "unsubscribe" followed by the list name: unsubscribe demo-list (This command may fail if your provider has changed the way your address is shown in your mail.) To remove an address other than the one from which you're sending the request, give that address in the command: unsubscribe demo-list jqpublic(a)my-isp.com In either of these cases, you can tell Majordomo(a)tradinghouse.com to remove the address in question from all lists on this server by using "*" in place of the list name: unsubscribe * unsubscribe * jqpublic(a)my-isp.com IV. FINDING THE LISTS TO WHICH AN ADDRESS IS SUBSCRIBED To find the lists to which your address is subscribed, send this command in the body of a mail message to Majordomo(a)tradinghouse.com: which You can look for other addresses, or parts of an address, by specifying the text for which Majordomo should search. For instance, to find which users at my-isp.com are subscribed to which lists, you might send the command which my-isp.com Note that many list owners completely or fully disable the "which" command, considering it a privacy violation. V. FINDING OUT WHO'S SUBSCRIBED TO A LIST To get a list of the addresses on a particular list, you may use the "who" command, followed by the name of the list: who demo-list Note that many list owners allow only a list's subscribers to use the "who" command, or disable it completely, believing it to be a privacy violation. VI. RETRIEVING FILES FROM A LIST'S ARCHIVES Many list owners keep archives of files associated with a list. These may include: - back issues of the list - help files, user profiles, and other documents associated with the list - daily, monthly, or yearly archives for the list To find out if a list has any files associated with it, use the "index" command: index demo-list If you see files in which you're interested, you may retrieve them by using the "get" command and specifying the list name and archive filename. For instance, to retrieve the files called "profile.form" (presumably a form to fill out with your profile) and "demo-list.9611" (presumably the messages posted to the list in November 1996), you would put the lines get demo-list profile.form get demo-list demo-list.9611 in your mail to Majordomo(a)tradinghouse.com. VII. GETTING MORE HELP To contact a human site manager, send mail to Majordomo-Owner(a)tradinghouse.com. To contact the owner of a specific list, send mail to that list's approval address, which is formed by adding "-approval" to the user-name portion of the list's address. For instance, to contact the list owner for demo-list(a)tradinghouse.com, you would send mail to demo-list-approval(a)tradinghouse.com. To get another copy of this help message, send mail to Majordomo(a)tradinghouse.com with a line saying help in the message body. VIII. COMMAND SUMMARY FOR ADVANCED USERS In the description below items contained in []'s are optional. When providing the item, do not include the []'s around it. Items in angle brackets, such as <address>, are meta-symbols that should be replaced by appropriate text without the angle brackets. It understands the following commands: subscribe <list> [<address>] Subscribe yourself (or <address> if specified) to the named <list>. unsubscribe <list> [<address>] Unsubscribe yourself (or <address> if specified) from the named <list>. "unsubscribe *" will remove you (or <address>) from all lists. This _may not_ work if you have subscribed using multiple addresses. get <list> <filename> Get a file related to <list>. index <list> Return an index of files you can "get" for <list>. which [<address>] Find out which lists you (or <address> if specified) are on. who <list> Find out who is on the named <list>. info <list> Retrieve the general introductory information for the named <list>. intro <list> Retrieve the introductory message sent to new users. Non-subscribers may not be able to retrieve this. lists Show the lists served by this Majordomo server. help Retrieve this message. end Stop processing commands (useful if your mailer adds a signature). Commands should be sent in the body of an email message to "Majordomo(a)tradinghouse.com". Multiple commands can be processed provided each occurs on a separate line. Commands in the "Subject:" line are NOT processed. If you have any questions or problems, please contact "Majordomo-Owner(a)tradinghouse.com".
