# Direct Interconnect VLAN Attachment and router
This module allows creation of a VLAN attachment for Direct Interconnect and router (router creation is optional).
## Examples
### Direct Interconnect VLAN attachment using default parameters for bgp session and router
```hcl
module "vlan-attachment-1" {
source = "./fabric/modules/net-interconnect-attachment-direct"
project_id = "dedicated-ic-5-8492"
region = "us-west2"
router_network = "myvpc"
name = "vlan-604-x"
interconnect = "https://www.googleapis.com/compute/v1/projects/mylab/global/interconnects/mylab-interconnect-1"
peer = {
ip_address = "169.254.63.2"
asn = 65418
}
}
# tftest modules=1 resources=4
```
#### Direct Interconnect VLAN attachments to achieve 99.9% SLA setup
```hcl

description = ""
asn = 65003
advertise_config = {
groups = ["ALL_SUBNETS"]
ip_ranges = {
"199.36.153.8/30" = "custom"
}
mode = "CUSTOM"
}
}
router_network = "myvpc"
name = "vlan-603-1"
