Parameters

Name	In	Type	Description
`id` (Optional)	query	string	Filter the list result by the ID of the router.
`tenant_id` (Optional)	query	string	Filter the list result by the ID of the project that owns the resource.
`project_id` (Optional)	query	string	Filter the list result by the ID of the project that owns the resource.
`name` (Optional)	query	string	Filter the list result by the human-readable name of the resource.
`description` (Optional)	query	string	Filter the list result by the human-readable description of the resource.
`admin_state_up` (Optional)	query	boolean	Filter the list result by the administrative state of the resource, which is up (`true`) or down (`false`).
`revision_number` (Optional)	query	integer	Filter the list result by the revision number of the resource.
`sort_dir` (Optional)	query	string	Sort direction. A valid value is `asc` (ascending) or `desc` (descending). You can specify multiple pairs of sort key and sort direction query parameters.
`sort_key` (Optional)	query	string	Sorts by a router attribute. You can specify multiple pairs of sort key and sort direction query parameters. The sort keys are limited to: `admin_state_up` `flavor_id` `id` `name` `status` `tenant_id` `project_id`
`tags` (Optional)	query	string	A list of tags to filter the list result by. Resources that match all tags in this list will be returned. Tags in query must be separated by comma.
`tags-any` (Optional)	query	string	A list of tags to filter the list result by. Resources that match any tag in this list will be returned. Tags in query must be separated by comma.
`not-tags` (Optional)	query	string	A list of tags to filter the list result by. Resources that match all tags in this list will be excluded. Tags in query must be separated by comma.
`not-tags-any` (Optional)	query	string	A list of tags to filter the list result by. Resources that match any tag in this list will be excluded. Tags in query must be separated by comma.
`fields` (Optional)	query	string	The fields that you want the server to return. If no `fields` query parameter is specified, the networking API returns all attributes allowed by the policy settings.

For example, if you specify `fields=id&fields=name` in the request URL, only the `id` and `name` attributes will be returned.

Parameters

Name	In	Type	Description
`routers`	body	array	A list of `router` objects.
`id`	body	string	The ID of the router.
`tenant_id`	body	string	The ID of the project.
`project_id`	body	string	The ID of the project.
`name`	body	string	Human-readable name of the resource.
`description`	body	string	A human-readable description for the resource.
`admin_state_up`	body	boolean	The administrative state of the resource, which is up (`true`) or down (`false`).
`status`	body	string	The router status.
`external_gateway_info`	body	object	The external gateway information of the router. If the router has an external gateway, this would be a dictionary of `network_id`, `enable_snat` and `external_fixed_ips`. Otherwise, this would be `null`.
`network_id`	body	string	Network ID which the router gateway is connected to.
`enable_snat`	body	boolean	Enable Source NAT (SNAT) attribute. `true` means Network Address Translation (NAT) is enabled for traffic generated by subnets attached to the router when the traffic is sent to/received from the external network. `false` means no NAT is applied for traffic from/to the external network. It is available when `ext-gw-mode` extension is enabled.
`external_fixed_ips`	body	array	IP address(es) of the external gateway of the router. It is a list of IP addresses. Each element of the list is a dictionary of `ip_address` and `subnet_id`.
`revision_number`	body	integer	The revision number of the resource.
`routes`	body	array	The extra routes configuration for L3 router. A list of dictionaries with `destination` and `nexthop` parameters. It is available when `extraroute` extension is enabled.
`destination`	body	string	The destination CIDR.
`nexthop`	body	string	The IP address of the next hop for the corresponding destination. The next hop IP address must be a part of one of the subnets to which the router interfaces are connected.
`distributed`	body	boolean	`true` indicates a distributed router. It is available when `dvr` extension is enabled.
`ha`	body	boolean	`true` indicates a highly-available router. It is available when `l3-ha` extension is enabled.
`availability_zone_hints`	body	array	The availability zone candidates for the router. It is available when `router_availability_zone` extension is enabled.
`availability_zones`	body	array	The availability zone(s) for the router. It is available when `router_availability_zone` extension is enabled.
`service_type_id`	body	string	The ID of the service type associated with the router.
`flavor_id`	body	string	The ID of the flavor associated with the router.
`created_at`	body	string	The date and time when the resource was created. The date and time stamp format is ISO 8601: CCYY-MM-DDThh:mm:ss±hh:mm For example, `2015-08-27T09:49:58-05:00`. The `±hh:mm` value, if included, is the time zone as an offset from UTC. In this example, the offset value is `-05:00`.
`updated_at`	body	string	The date and time when the resource was updated. If the resource has not been updated, this field will be `null`. The date and time stamp format is ISO 8601: CCYY-MM-DDThh:mm:ss±hh:mm For example, `2015-08-27T09:49:58-05:00`. The `±hh:mm` value, if included, is the time zone as an offset from UTC. In this example, the offset value is `-05:00`.
`tags`	body	array	The list of tags on the router.
`conntrack_helpers`	body	array	The associated conntrack helper resources for the router. If the router has multiple conntrack helper resources, this field has multiple entries.
