NCC Spoke RA Module

This module allows management of NCC Spokes backed by Router Appliances. Network virtual appliances used as router appliances allow to connect an external network to Google Cloud by using a SD-WAN router or another appliance with BGP capabilities (site-to-cloud connectivity). It is also possible to enable site-to-site data transfer, although this feature is not available in all regions, particularly not in EMEA.

The module manages a hub (optionally), a spoke, and the corresponding Cloud Router and BGP sessions to the router appliance(s).

Examples

Simple hub & spoke

module "spoke-ra" {
  source     = "./fabric/modules/ncc-spoke-ra"
  hub        = { create = true, name = "ncc-hub" }
  name       = "spoke-ra"
  project_id = var.project_id
  region     = var.region
  router_appliances = [
    {
      internal_ip  = module.compute-vm-primary-b.internal_ip
      vm_self_link = module.compute-vm-primary-b.self_link
    }
  ]
  router_config = {
    asn           = 65000
    ip_interface0 = "10.0.16.14"
    ip_interface1 = "10.0.16.15"
    peer_asn      = 65001
  }
  vpc_config = {
    network_name     = var.vpc.self_link
    subnet_self_link = var.subnet.self_link
  }
}
