Dear Colleagues,
(Apologies for multiple messages).
This is to announce that we have completed the phase 1 of migration.
Starting from today, Monday, 14th May, 2001, <auto-dbm(a)ripe.net> shall only accept
updates in RPSL format; updates in RIPE-181 format will no longer be accepted.
Updates in RIPE-181 format can be sent to <auto-181(a)ripe.net>, where they
will be automatically converted to RPSL format. <auto-rpsl(a)ripe.net> will
continue to accept updates in RPSL format. The update path for the TEST
database has also been changed.
In summary, from 14th May, 2001:
===============================
RIPE Database:
-------------
<auto-dbm(a)ripe.net> - updates in RPSL format only
<auto-rpsl(a)ripe.net> - updates in RPSL format only
<auto-181(a)ripe.net> - updates in RIPE-181 format, automatically
converted to RPSL format
TEST Database:
-------------
<test-dbm(a)ripe.net> - updates in RPSL format only
<test-rpsl(a)ripe.net> - updates in RPSL format only
<test-181(a)ripe.net> - updates in RIPE-181 format, automatically
converted to RPSL format
Please note that from Monday, 15th October, 2001, updates in RIPE-181 format
will no longer be accepted by the RIPE Database.
Further information is available from http://www.ripe.net/rpsl/.
If you have any questions, please contact <ripe-dbm(a)ripe.net>.

End of report
Dear Colleagues,
(Apologies for multiple messages).
On and from Monday, 14th May, 2001, <auto-dbm(a)ripe.net> shall only accept
updates in RPSL format; updates in RIPE-181 format will no longer be accepted.
Updates in RIPE-181 format can be sent to <auto-181(a)ripe.net>, where they
will be automatically converted to RPSL format. <auto-rpsl(a)ripe.net> will
continue to accept updates in RPSL format. The update path for the TEST
database will also be changed.
In summary, from 14th May, 2001:
===============================
RIPE Database:
- -------------
<auto-dbm(a)ripe.net> - updates in RPSL format only
<auto-rpsl(a)ripe.net> - updates in RPSL format only
<auto-181(a)ripe.net> - updates in RIPE-181 format, automatically converted to RP
S
L format
TEST Database:
- -------------
<test-dbm(a)ripe.net> - updates in RPSL format only
<test-rpsl(a)ripe.net> - updates in RPSL format only
<test-181(a)ripe.net> - updates in RIPE-181 format, automatically converted to RP
S
L format
On Monday, 14th May, 2001, we cannot guarantee that an update message sent to
<auto-dbm(a)ripe.net> will use a specific update path (RPSL or RIPE-181). Thus,
we advise that updates in RIPE-181 format should be sent to <auto-181(a)ripe.net>
and that updates in RPSL format should be sent to <auto-rpsl(a)ripe.net>.
Please note that from Monday, 15th October, 2001, updates in RIPE-181 format
will no longer be accepted by the RIPE Database.
Further information is available from http://www.ripe.net/rpsl/.
If you have any questions, please contact <ripe-dbm(a)ripe.net>.

It is not checked before it leaves my workstation. However, hopefully
you will find this report interesting and will take the time to look
through this to see if you can improve the amount of aggregation you
perform.
The report is split into sections:
0) General Status
List the route table history for the last week, list any possibly
bogus routes seen and give some status on ASes.
1) Gains by aggregating at the origin AS level
This lists the "Top 30" players who if they decided to aggregate
their announced classful prefixes at the origin AS level could
make a significant difference in the reduction of the current
size of the Internet routing table. This calculation does not
take into account the inclusion of holes when forming an aggregate
so it is possible even larger reduction should be possible.
2) Weekly Delta
A summary of the last weeks changes in terms of withdrawn and
added routes. Please note that this is only a snapshot but does
give some indication of ASes participating in CIDR. Clearly,
it is generally a good thing to see a large amont of withdrawls.
3) Interesting aggregates
Interesting here means not an aggregate made as a set of
classful routes.
Thanks to xara.net for giving me access to their routing tables once a
day.
Please send any comments about this report directly to me.
