Thread Index RE: [isp-bgp] IX core - public or private ASN?
It will be a layer-3 IX, each of participant's routers peer with each one of the two IX core routers. The 2 core routers will be running ibpg in a separate ASN, so my question is: It would be better using a private or public ASN? An additional question to do would be, if we decided to use a public ASN, Does the local regional registry (in my case LACNIC) have to assign one for us? I mention this, as i've read LACNIC policies and they not consider the use of a ASN public for IX infraestructure. Is it the same with other registries?

Is this a layer-2 exchange or layer-3? In North America and Europe, most IXes are layer-2 where participants peer with each other and IX has no say in each participant's specific routing policy. However, often in other countries, we see "layer-3 IX", which the IX basically acts like a transit provider in essence. Simplest way to setup a layer-2 IX: 1. Install a switch (preferably a switch that supports 802.1Q and various SP-like features e.g. Cisco, but for low-budget starters, even a decent netgear would do for temporary start). 2. Allocate a peering LAN block (ie. www.ep.net, and request a block + pay bill, or RIPE and ARIN have similar service, see "critical infrastructure assignment") 3. put together a couple PCs running Zebra or recycled cisco boxes for route-servers if you want people to do MLPA. Most exchanges do not prefer MLPA peering (neither do I), and people often just get away with one server for 'route collection' and statistical purposes.
