# 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
```hcl
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
```hcl
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
```hcl
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"
}
# tftest modules=1 resources=8
```
