Dear Colleagues, Because of a very high level of use this afternoon, the response time of <auto-dbm(a)ripe.net> is longer than normal. I have made contact with those who are responsible and I expect the situation to improve as the machine works through the queue. Please be patient. Obviously we at the RIPE NCC Database Group are continuously working to make the performance of the database as good as possible. However, we cannot make improvements in zero time. We thank you for your co-operation up to now and we ask for your continued co-operation so that everyone receives the best possible service. If you have anymore questions, please contact <ripe-dbm(a)ripe.net>. Regards, Ambrose Magee ____________________________ RIPE Database Administration.

Andrei, The existing ripe2rpsl tool will automatically translate "AS-" to "ASN-" for the aut-num object and I think "ASN-" is more meaningful than "AS_". Best Regards.

Another issue related to the migration
by Andrei Robachevsky 29 Mar '01

29 Mar '01

Dear Colleagues, [Apologies for duplicate messages] One issue related to RIPE-181 to RPSL migration escaped our attention and has not been discussed. It is related to reserved prefixes that cannot appear in object names according to RPSL specification (RFC2622) which says: "Names starting with certain prefixes are reserved for certain object types. Names starting with "as-" are reserved for as set names. Names starting with "rs-" are reserved for route set names. Names starting with "rtrs-" are reserved for router set names. Names starting with "fltr-" are reserved for filter set names. Names starting with "prng-" are reserved for peering set names." Unfortunately "as-name:" attribute is an object name in RPSL and we have 133 aut-num objects with as-name starting with reserved 'AS-' prefix. Our suggestion how to deal with these objects is: 1. Send a message to the maintainers of these objects asking them to change the name to avoid conflict with RPSL specification. 2. Give two-week notice period after which ripe-dbm will convert non compliant as-names using the following mapping: AS-ASNAME -> AS_ASNAME. This is more a "cosmetic" change as as-name is not even a lookup key in the RIPE Database. Your comments and suggestions are appreciated. Best regards, Andrei Robachevsky DB Group Manager RIPE NCC

Summary of the Migration issues
by Andrei Robachevsky 20 Mar '01

20 Mar '01

Dear Colleagues, Please let me summarize the migration issues that have been discussed already and highlight some issues that require more attention. Best regards, Andrei Robachevsky DB Group Manager RIPE NCC ---------------------------------------- 1. Route object creation (RFC2725 implications) In order to create route object in the RIPE DB, one needs to have corresponding objects (inetnum or less specific route, and aut-num) and pass proper authorization from these objects. The problem occurs when someone needs to register route object which has either prefix, or origin, or the both from non RIPE IP/ASN space. Proposed solution: 1.1 An as-block object(s) encompassing the non RIPE ASN space will be created with "mnt-lower:" protected by mntner with NONE auth. 1.2 An encompassing inetnum object with "mnt-routes:" protected by mntner with NONE auth will be created. This will eliminate need for corresponding inetnum creation and will reduce amount of redundant information. 1.3 In case origin of a route object being created is from non RIPE space, users will need to create corresponding aut-num object in the RIPE DB. 2. Updates in RIPE-181 format Migration plan allows users to send updates in RIPE-181 format for some time (until May 14th to <auto-dbm(a)ripe.net>, from May 14th till October 15th to <auto-181(a)ripe.net>) after the migration. In such case objects are automatically converted to RPSL. However the switchover to the new version of the RIPE Database occurs on 23 of April, and since then the following constraints will apply: 2.1 PGP authentication PGP authorization scheme will not work with <auto-dbm(a)ripe.net> robot after 23 April. Updates requiring PGP auth should be sent directly to <auto-rpsl(a)ripe.net>. The problem occurs because after ripe181->RPSL transformation it is impossible to verify signature. For this reason, some updates requiring PGP auth may be rejected during migration. It advisable not to send such updates from 22 April, 9a.m. till 23 April 9a.m. 2.2 New syntax rules When processing an object after ripe181->RPSL conversion new v3.0 syntax rules apply. The results of this will be: - empty attributes (i.e. having no value) are not allowed; - some attributes that were optional before are now mandatory; Also some undocumented behaviour of the v2.x Database will not be supported, namely: - attribute aliases (please see list of aliases attached) are not allowed; - inetnum object cannot be specified in prefix notation. 2.3 New authorization rules New authorization rules defined by RFC2725 apply to creation of aut-num and route objects. See 1. 3. Objects with names containing reserved RPSL prefixes They will be renamed on 2 of April. All references will be updated accordingly. Currently there are 6 of them in the RIPE Database. mntner: AS-5532MNTB mntner: AS-NETLINK-MNT mntner: AS-THENET-MNT mntner: AS-NEW1-MNT mntner: RS-MNT mntner: AS-MNT 4. Broken PGP certificates. They will be deleted on 2 of April. ---------------------- v2.x attribute aliases (not supported in v3.0!): Alias Attrbute change -> changed email -> e-mail fax -> fax-no remark -> remarks deleted -> delete asname -> as-name rev-svr -> rev-srv network -> inetnum netnum -> inetnum

RFC2725
by Holger Muenx 15 Mar '01

15 Mar '01

Guten Tag, I hope this is the correct forum - if not please direct me to a more appropriate one. After following the discussion for a while I am still unsure about the exact consequences of the activation of RFC2725 on 23-Apr-2001. I will try to summarize my understanding: Please check this and correct me where necessary. You will find a list of open questions at the bottom of this mail. As Frank Bohnsack wrote in http://www.ripe.net/ripe/mail-archives/db-wg/current/msg00090.html AS numbers are allocated to regional registries as shown in http://www.isi.edu/in-notes/iana/assignments/as-numbers and the IPv4 address space allocated to various registries as shown in http://www.isi.edu/in-notes/iana/assignments/ipv4-address-space RFC2725 states in section 9.9 that during addition of an inetnum the most specific matching inetnum is being searched to find the required authentication. During addition of a route the aut-num of the originating AS and either a most specific matching inetnum or a most specific matching route is being searched to find the required authentication. This leaves UUNET in a curious situation. For example, UUNET uses AS 702 which is in the range 1 - 1876 allocated by the ARIN and the inetnum 193.96.0.0/13 which is in 193.0.0.0/8 allocated by the RIPE. With RFC2725 in place UUNET would have its aut-num record in a different registry than its inetnum, rendering it impossible to add routes for the 193.0.0.0/8. There are probably more complications caused by moving data from one registry to another. For example, some people will continue to expect information at the original registry because they did not prepare for RFC2725, breaking mechanisms such as automatic prefix filter creation. Andrei Robachevsky presented two suggestions in http://www.ripe.net/ripe/mail-archives/db-wg/current/msg00095.html Suggestion 1 means that RIPE will implement changes so that RFC2725 will be in effect for AS numbers and IP address space allocated by RIPE only. No checks according to RFC2725 will be done for all other AS numbers and IP address space. Suggestion 2 means that there will be encompassing inetnum objects which contain the address ranges assigned to other registries than RIPE. These objects will have a maintainer with NONE authentication so that everybody can add routes within these inetnum which refer to their own aut-num records. No decision has been made on whether one of the suggestion and, if so, which of them will be implemented. So far my understanding. Please review - if it is completely wrong I hope that I at least amused you. ;-) Thank you for your help!

That's an option for RIPE-DB v2.x (RIPE-181) but we haven't tried RIPE-DB v3.x yet. Also the workaround raises another question: How do you authorize the route creation from a foreign AS ? That's exactly the issue from Andrei's previous email (subject: Migration issues: route creation). And the solution to this needs to be discussed further.

RE: RIPE DB transition and RFC2725
by Lu, Ping 09 Mar '01

Finally somebody express the same concerns as ours. I have a discussion with the RIPE staff at the RIPE-38 meeting about this. There are two seperate issues here: 1. The RFC doesn't say a implementation (like RIPE-DB v3.0) should allow foreign references ( using objects from other RR database) or not. 2. The assumption of RIPE-DB v3.0 is that all object references have to be resloved locally( ie. with source: RIPE). The 2nd issue means if any ISP with ARIN's AS number want to register a route with RIPE you have to register your PN(person) then your MT(mntner) then your AN(aut-num) with RIPE first. So each ISP has to maintain a different set of objects with each RR. AS123(in RIPE) -> MNT-AS123-RIPE -> NIC456-RIPE AS123(in ARIN) -> MNT-AS123-ARIN -> NIC456-ARIN AS123(in APNIC) -> MNT-AS123-APNIC -> NIC456-APNIC AS123(in JP) -> MNT-AS123-JP -> NIC456-JP AS123(in DE) -> MNT-AS123-DE -> NIC456-DE .... Just to remember to update all these information everytime there is a little tiny change. It is fun, isn't it ? And NO you can't get all route information from just one RR unless we all sit down and seriously talking about the GLOBAL issues.
