Hi all, As mentioned in an e-mail to pretty much everybody last week, I will be changing our advertisements across NZIX to remove all the long-prefix subnets we currently advertise across the NZIX OSPF process and replace them with less-specific supernet routes. Note that the supernet routes I announce will be exactly the same length as those CLEAR advertise via BGP to Netgate, Telstra, MCI and Teleglobe. This may make you prefer an international route to CLEAR rather than using the exchange, since routes learnt by BGP from external neighbours are frequently preferred to OSPF-learnt routes. If this applies to you, then there are two options open that I can see: 1. We are perfectly willing to talk BGP to anybody on NZIX. In fact, any opportunity not to run OSPF across NZIX would be most welcome :) Please mail noc(a)clix.net.nz to set this up. 2. On Ciscos you can lower the administrative distance of the NZIX OSPF process so that it is preferred over EBGP (or raise the corresponding distance metric on the BGP process to make it less preferable). This is what some on the Exchange are doing already, I believe. I will be doing as much testing as I can following the change, and if there are problems I will back the change out. I expect to start (and hopefully finish) changes between 0400 and 0800 tomorrow morning. If you (or your customers) notice any loss in connectivity to CLEAR or to CLEAR-connected networks I would be very grateful for the feedback. Please mail any reports to noc(a)clix.net.nz.
