Waikato has no objection to carriers or ISP's running BGP meshes at the NZIX if it provides a more robust service. However from Waikato's perspective (and possibly for other smaller NZIX users) we would prefer that routers connected to the NZIX also ran OSPF as we use this process to collect NZ routes and differentiate between domestic and international traffic for our campus IP traffic metering.It is possible that other NZIX users do the same. OSPF is also less complex to manage for smaller users with fewer highly skilled network staff.

If we can get agreement from the other main providers (by which I mean those who do not transit another NZ provider for global access) to run BGP, then we will be keen to stop running OSPF at NZIX. Other exchange participants who are unwilling or unable to run BGP will still be able to reach our networks via their transit providers' BGP peering with CLEAR. Any routes you receive by BGP from us can be interpreted as "domestic" routes - similarly for Telstra NZ and IBM, I would suppose. For our customers we apply community tags to routes so that customers can differentiate between routes learnt from off-shore BGP peers, and those learnt from within NZ - I would imagine that Telecom can do something similar for you. This being the case, I don't really see how extracting routes from OSPF is any easier than BGP - if anything BGP is easier, since you have a much clearer picture (from the AS-path) of where the routes originated, and hence more automated checks are possible to ensure that the "domestic table" is accurate. Naturally, this is not a change that you will want to make overnight, and your requirements should be included in the timeline for a BGP transition if at all possible.
