Hi fellow operators, We are slowly and carefully joining the fray of autonomous systems and started announcing our own netblock, a first test that started last week. So far, things are going well, but before going further along this setup, I would be curious to hear experience from other operators about the plan we are thinking of deploying. Our requirements: * free software, as much as possible * inexpensive * using existing operating system expertise (FreeBSD or Debian) So far, we have: * our own ASN * a /21 assigned by ARIN * two uplinks deployed (Netelligent and Cogent) * Netelligent announces 3 /24 netblocks for us * we announce the last /24 through a BGP link with cogent We have some horrible diagrams describing the setup here: https://wiki.koumbit.net/RoutingService/RoadMap As you can see, the uplinks are connected directly into a switch, in two separate VLANs. The reason for this is we want to be able to hotswap the routers in case of a hardware failure, but we have understood from Cogent's documentation that this is not a good practice because the links appears up even if the router goes down. What is your opinion on this? Also, we currently testing OpenBGPd for the announcements, and we are very pleased with it. The syntax is clear and it just works, with minimal memory usage: https://wiki.koumbit.net/OpenBgpdMaintenance#Checking_memory_usage However, this seems to be a fairly exotic platform, most people running BGP with Cisco, Juniper or, in some cases Quagga or Bird for Linux machines. Are there recmomendations on using OpenBGP in production? Good / bad experiences? How many people are running Linux routers vs dedicated Cisco/Juniper/etc routers? Finally, we are likely to complete this setup with a CARP (the free equivalent of VRRP) on the inside of the network. FreeBSD can apparently group interfaces and communicate with OpenBGPd - did anyone deploy such a thing here? What are your experiences or advice? Thanks for any advice, A. -- Sous un gouvernement qui emprisonne injustement, la place de l’homme juste est aussi en prison. - La désobéissance civile, Henry David Thoreau
