# PUT /v20190125/meshes/{meshName}/virtualRouters

`PUT /v20190125/meshes/{meshName}/virtualRouters`

Creates a virtual router within a service mesh.

Specify a `listener` for any inbound traffic that your virtual router receives. Create a virtual router for each protocol and port that you need to route. Virtual routers handle traffic for one or more virtual services within your mesh. After you create your virtual router, create and associate routes for your virtual router that direct incoming requests to different virtual nodes.

For more information about virtual routers, see [Virtual routers](https://docs.aws.amazon.com/app-mesh/latest/userguide/virtual_routers.html).

## Path parameters

- `meshName` string, required

## Query parameters

- `meshOwner` string

## Request body

- object
  - `clientToken` string — Unique, case-sensitive identifier that you provide to ensure the idempotency of the request. Up to 36 letters, numbers, hyphens, and underscores are allowed.
  - `spec` object, required — An object that represents the specification of a virtual router.
    - `listeners` VirtualRouterListener[] — The listeners that the virtual router is expected to receive inbound traffic from. You can specify one listener.
      - `portMapping` PortMapping, required — An object that represents a port mapping.
        - `port` integer, required — The port used for the port mapping.
        - `protocol` 'http' | 'tcp' | 'http2' | 'grpc', required — The protocol used for the port mapping. Specify one protocol.
  - `tags` TagRef[] — Optional metadata that you can apply to the virtual router to assist with categorization and organization. Each tag consists of a key and an optional value, both of which you define. Tag keys can have a maximum character length of 128 characters, and tag values can have a maximum length of 256 characters.
    - `key` string, required — One part of a key-value pair that make up a tag. A <code>key</code> is a general label that acts like a category for more specific tag values.
    - `value` string, required — The optional part of a key-value pair that make up a tag. A <code>value</code> acts as a descriptor within a tag category (key).
  - `virtualRouterName` string, required — The name to use for the virtual router.
