Hi all,
CLEAR currently advertises connectivity to its internal networks and those
of its customers across NZIX.
The external routes which are currently redistributed into the exchange
OSPF process include a large number of long-prefix routes, such as /30s
and /28s; in the interests of being tidy (and consistent with CLEAR's BGP
advertisements) I would like to summarise most, if not all, of these
advertisements by distributing supernet routes.
For example, instead of >100 individual routes within CLEAR's
203.97.0.0/17 CIDR block, I would like to advertise a single 203.97.0.0/17
supernet route. Total number of supernets to be announced would be around
30.
This approach presupposes that (a) all equipment connected to the exchange
can handle supernetting, and (b) that the loss of specificity in the
domestic routes for CLEAR's networks is not going to cause problems with
conflicting BGP routes picked up from other global transit providers.
There may also be route filters which need to be updated.
In the interests of maintaining connectivity within NZ, I would be
grateful if you could take the time to consider whether the changes
broadly outlined above will affect the way that your network treats routes
to CLEAR across NZIX. If you could give me some feedback (no matter how
general) this week, it would be most appreciated.
I have attempted to distribute this message to as many exchange partners
as I have been able to find e-mail addresses for - please feel free to
forward copies on to other interested parties.
As an aside, the NZNOG list operated (facilitated?) by Donald Neal at
Waikato Univeristy would provide a good forum for these kinds of
announcements in future. If you haven't already, you might consider
subscribing - send mail to majordomo(a)list.waikato.ac.nz with the line
"subscribe nznog" in the message body (Donald please correct me if I've
stuffed that up :)
Regards,
Joe
