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 = "my-project"
  asn        = 65000
  peer_asn   = 65001
  ras = [
    {
      vm = "projects/my-project/zones/europe-west1-b/instances/router-app"
      ip = "10.0.0.3"
    }
  ]
  region     = "europe-west1"
  subnetwork = var.subnet.self_link
  vpc        = "my-vpc"
}
# tftest modules=1 resources=7

Two spokes

module "spoke-ra-a" {
  source     = "./fabric/modules/ncc-spoke-ra"
  hub        = { name = "ncc-hub" }
  name       = "spoke-ra-a"
  project_id = "my-project"
  asn        = 65000
  peer_asn   = 65001
  ras = [
    {
      vm = "projects/my-project/zones/europe-west1-b/instances/router-app-a"
      ip = "10.0.0.3"
    }
  ]
  region     = "europe-west1"
  subnetwork = "projects/my-project/regions/europe-west1/subnetworks/subnet"
  vpc        = "my-vpc1"
}

module "spoke-ra-b" {
  source     = "./fabric/modules/ncc-spoke-ra"
  hub        = { name = "ncc-hub" }
  name       = "spoke-ra-b"
  project_id = "my-project"
  asn        = 65000
  peer_asn   = 65002
  ras = [
    {
      vm = "projects/my-project/zones/europe-west3-b/instances/router-app-b"
      ip = "10.1.0.5"
    }
  ]
  region     = "europe-west3"
  subnetwork = "projects/my-project/regions/europe-west3/subnetworks/subnet"
  vpc        = "my-vpc2"
}
# tftest modules=2 resources=12

Spoke with load-balanced router appliances

module "spoke-ra" {
  source     = "./fabric/modules/ncc-spoke-ra"
  hub        = { name = "ncc-hub" }
  name       = "spoke-ra"
  project_id = "my-project"
  asn        = 65000
  custom_advertise = {
    all_subnets = true
    ip_ranges = {
      "peered-vpc" = "10.10.0.0/24"
    }
  }
  ip_intf1 = "10.0.0.14"
  ip_intf2 = "10.0.0.15"
  peer_asn = 65001
  ras = [
    {
      vm = "projects/my-project/zones/europe-west1-b/instances/router-app-a"
      ip = "10.0.0.3"
    },
    {
      vm = "projects/my-project/zones/europe-west1-c/instances/router-app-b"
      ip = "10.0.0.4"
    }
  ]
  region     = "europe-west1"
  subnetwork = var.subnet.self_link
  vpc        = "my-vpc"
}
