Redirect to view display after form submission
Routes are not only defined in yaml files, but also dynamically in route subscribers.

Drupal\views\EventSubscriber\RouteSubscriber collects routes from all views displays which implement DisplayRouterInterface::collectRoutes, like the Page display:

PathPluginBase::collectRoutes:

  public function collectRoutes(RouteCollection $collection) {
    $view_id = $this-&gt;view-&gt;storage-&gt;id();
    $display_id = $this-&gt;display['id'];

    $route = $this-&gt;getRoute($view_id, $display_id);

    if (!($route_name = $this-&gt;getOption('route_name'))) {
      $route_name = "view.$view_id.$display_id";
    }
    $collection-&gt;add($route_name, $route);
    return ["$view_id.$display_id" =&gt; $route_name];
  }


This produces route names like view.my_view.page_1 and you can redirect in a form submit:

$form_state-&gt;setRedirect('view.my_view.page_1');
