// associated HTTP connection manager filters) to use different route
// configurations. Each listener will bind its HTTP connection manager filter to
// a route table via this identifier.

// Virtual Host Discovery Service (VHDS) is used to dynamically update the list of virtual hosts for
// a given RouteConfiguration. If VHDS is configured a virtual host list update will be triggered
// during the processing of an HTTP request if a route for the request cannot be resolved. The
// :ref:`resource_names_subscribe `
// field contains a list of virtual host names or aliases to track. The contents of an alias would
// be the contents of a ``host`` or ``authority`` header used to make an http request. An xDS server
// will match an alias to a virtual host based on the content of :ref:`domains'
// ` field. The ``resource_names_unsubscribe`` field
// contains a list of virtual host names that have been :ref:`unsubscribed
// ` from the routing table associated with the RouteConfiguration.
