NeoNetwork Recommended Setup:

Part 0: Routing Protocols

  • BGP for EGP, the use of MP-BGP is encouraged
  • OSPF for IGP, there's not much reason to use anything else these days, especially with pure software-based solution

Part 1: Intra-AS (within your own AS) WireGuard configs

  • Use IPv4 Link-Local addresses in point-to-point tunnels (such that all internal routing is determined by your IGP of choice)
  • Only IPv6 loopback address is required to run OSPFv3
  • Actual IPv4/IPv6 address for a node should be on a loopback interface
  • Remember to set src addr to node addresses

Part 2: Inter-AS (tunnels interfacing with other AS) WireGuard configs

  • Use Link-Local or Point-to-Point addresses, depending on your (or your peer's) taste
  • Older versions (before 8.5.1) of FRRouting have problems interfacing with BIRD when using Link-Local addresses, choose Point-to-Point in this case
  • Point-to-Point setup requires less config in FRRouting

Part -1: (Un)Common Pitfalls

  • DO NOT RUN IGP ON AN INTERFACE THAT MIGHT CONTAIN PUBLIC IP (This kickstarts route flapping, use MACVLAN to avoid it)
