Creates a routing entry on a OpenStack V2 router.

# openstack\_networking\_router_route_v2
Creates a routing entry on a OpenStack V2 router.
## Example Usage
```
resource "openstack_networking_router_v2" "router_1" {
name = "router_1"
admin_state_up = "true"
}
resource "openstack_networking_network_v2" "network_1" {
name = "network_1"
admin_state_up = "true"
}
resource "openstack_networking_subnet_v2" "subnet_1" {
network_id = "${openstack_networking_network_v2.network_1.id}"
cidr = "192.168.199.0/24"
ip_version = 4
}
resource "openstack_networking_router_interface_v2" "int_1" {
router_id = "${openstack_networking_router_v2.router_1.id}"
subnet_id = "${openstack_networking_subnet_v2.subnet_1.id}"
}
resource "openstack_networking_router_route_v2" "router_route_1" {
depends_on = ["openstack_networking_router_interface_v2.int_1"]
router_id = "${openstack_networking_router_v2.router_1.id}"
destination_cidr = "10.0.1.0/24"
next_hop = "192.168.199.254"
}
```
## Argument Reference
The following arguments are supported:
* `region` - (Required) The region in which to obtain the V2 networking client.
A networking client is needed to configure a routing entry on a router. If omitted, the
`OS_REGION_NAME` environment variable is used. Changing this creates a new
routing entry.
* `router_id` - (Required) ID of the router this routing entry belongs to. Changing
this creates a new routing entry.
* `destination_cidr` - (Required) CIDR block to match on the packet’s destination IP. Changing
this creates a new routing entry.
* `next_hop` - (Required) IP address of the next hop gateway. Changing
this creates a new routing entry.
## Attributes Reference
The following attributes are exported:
* `region` - See Argument Reference above.
* `router_id` - See Argument Reference above.
* `destination_cidr` - See Argument Reference above.
* `next_hop` - See Argument Reference above.
## Notes
The `next_hop` IP address must be directly reachable from the router at the ``openstack_networking_router_route_v2``
resource creation time. You can ensure that by explicitly specifying a dependency on the ``openstack_networking_router_interface_v2``
resource that connects the next hop to the router, as in the example above.
